Tests & Verdict

Here we collect tests, guides and product reviews so that you can create a picture of what others think about the product. This analysis and review is based on my experience and 12+ years of industry insight.

We really like the gel comfort layer, it is both breathable and soft with many of the bounce back and luxurious properties of an equivalent memory foam model.

Price point reasonable given the high quality materials utilised.

Pillow tops are a bit marmite in the industry, some love them, some do not. Think of it as a permanent mattress topper that cannot be removed, ideal for those who need a bit of extra comfort, but not suitable for all.

Why our sleep experts loved it

The TheraPur ActiGel® Glacier 3600 Mattress is one of the newer mattresses offered from Dreams and has some high-end properties that make it a great choice for your next mattress. Made in the UK by expert craftsmen, this mattress comes in medium tension, the middle-of-the-road, ideal choice, for the vast majority of the population. You may find this mattress slightly too firm if you have a very low BMI, while you may find the mattress too soft if you have a high BMI or suffer from back pain. Typically though, this is more likely to be a suitable choice.

The TheraPur ActiGel® Glacier 3600 Mattress mattress comes with a pillow top cover, this is like having a permanent mattress topper included with your mattress, this makes for effectively double the comfort. In practise, it can make putting on sheets a bit of a pain, but the minor inconvenience is generally offset by the additional comfort layer and quality.

To help prevent overheating while you sleep, the mattress comes with trademarked ActiCool fabrics that have cooling properties to ensure you are never too hot, nor cold while enjoying REM sleep.

Reviews for this mattress are strong with an impressive 600+ reviews and growing steadily. Satisfaction remains strong also, with 88% of people recommending the product after prolonged use. Positive feedback mainly comes from a subset of people who were suffering from back and neck pain who are now pain free for the first time in years. That alone should go a significant way in showing the pro points of such a mattress specification. It's not all good news however, a few of the one stars do mention some quality control issues on a small number of products through the covid era when manufacturing was gridlocked. The good news is that as normalcy resumes we are beginning to see these filter through and more positives stack up.

What's more, the TheraPur ActiGel® Glacier 3600 Mattress has a new brand ambassador in the form of Jade Jones, British Double Olympic Champion in Taekwondo. The athlete is keen to bring to light all the benefits of the mattress, stating "The TheraPur ActiGel® Glacier 3600 Mattress has been a real game changer for me in ensuring I’m well rested ahead of big training days and, most importantly, big competitions." Strong praise from someone who needs a deep sleep.

*some elements of this review and the reviews supported by customers were offered against the previous model known as the Therapur ActiGel Response 3200 Mattress. The Glacier 3600 Mattress is an upgraded model that takes everything that was great about the response and added more springs for enhanced support and better body contouring.

Suitability

*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • Back Sleepers
    ★★★★★
    ★★★★★
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers
    ★★★★★
    ★★★★★
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers
    ★★★★★
    ★★★★★
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.

Performance

  • Breathability
    ★★★★★
    ★★★★★
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress
    ★★★★★
    ★★★★★
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • Stability
    ★★★★★
    ★★★★★
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.

Odour

  • Initial Odour
    ★★★★★
    ★★★★★
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour
    ★★★★★
    ★★★★★
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

I am a full 3 weeks in and until the past week, was on the fence about this mattress. It was incredibly hard when it came and I wasn't sleeping very well or very long. The first night I recognized the signs that the mattress was too hard for me with my upper back incredibly sore and did not want to go to bed. The second night was slightly better but still not great. I decided to spend 10 mins daily "crawling" all over the mattress to try to work it in. By the second week I was sleeping better and it had softened a bit but not too much - my eyes felt SO tired. The third week in and it has softened considerably and now look forward to sleeping. I am asleep in about 10 mins max whenever I crawl into bed. I am a hot sleeper and so far haven't had any issues or at least am waking up to readjust before I am drenched in sweat (my previous mattress which I ADORE is latex and while I love it, do have issues with heat. Memory foam is completely out of the question). I can say that my mattress now feels like it did in store. The only thing is it does look like it has an indent that never fully went back where I typically sleep. It appeared after the first night and even though I have rotated it weekly, hasn't gone back. The strange thing is if I strip the bed, it doesn't look as obvious as it does with sheets on.

After trying a number of different mattresses over the last ten years including most recently an Emma Hybrid and still suffering with a stiff and aching back we tried our luck at a newly opened Dreams store. We were welcomed in, asked about our requirements and budget then popped onto the sleep system to determine what kind of mattresses were best suited. Once off the bed with a fresh coffee in one hand and a pillow in the other we were taken round to try out all the mattresses on the list. The TheraPur was I believe the second tried and I kept going back to it. I would have loved the first mattress we tried but that was way above our budget as it turned out the TheraPur was twice our budget but having tried all the mattresses on the list plus some more besides it was the TheraPur that I really felt the most comfortable on. So far, about three weeks in and no regrets! It is so comfortable, supportive and firm with the sprung mattress and soft (not too much) enough to feel cushioned with the memory foam topper. Its certainly not cheap but Im hopeful it will be an investment that pays dividends!!

Hope I have enough characters to express my feelings. Bought this mattress to replace my 12+ year old memory foam mattress. Had started with back pain long before lockdown, thought it was due to old mattress. We went to dreams as soon as we could once lockdown was lifted. We had a very helpful sales chap, went on the diagnostic bed that they have, tried the selection of mattresses that it recommended, eventually chose this mattress worried as it really is difficult to know how it is actually going to be once home and slept on. Reassured that as long as we kept the protector on, we could exchange it if not happy for uptown 30 days. I can honestly say that we really couldn't be happier. It may sound corny and forced, but I really am sleeping better, not waking at night and best of all - absolutely no back-pain. I rarely bother to write reviews, but I seriously and strongly recommend this mattress to anyone and everyone. We have the super-king zipped together model. A little more expensive, but really well worth the little extra. I really couldn't be happier.

The mattress is excellent as good as the previous acti gel mattress we purchased 5 years ago: which we only changed as there was a lump in the middle of the mattress making it difficult to get close. However we are dissapointed with your price match promise and try before you buy . On line this mattress was 100 cheaper: we requested the difference in price and was advised that as we did not request on purchase it was not available to us. This is not what was expected from Dreams surely it is a standard policy? If not is should be explained to the customer on purchase. Also the 40 day try before you can return is not explained fully Apparently you need to keep the matress for 30 days we are a little concerned that the dividing lump is already beginning to develop On a positve note Mark and his colleague delivering the matress was brilliant : unable to provide a review due to the term and conditions of your request This is very unfair to two excellent delivery people.

We purchased the mattress after trying it in store. It was incredibly comfortable and soft store so had no hesitation purchasing it. On arrival the first weeks sleep was fabulous however we started to notice the dips where our body weights are were not springing back. We are both quite light so wasnt due to this. There was a ridge in between the middle of the mattress starting to appear and after only a few weeks sleeping in it didnt feel confident it would be a mattress to last in comfort levels. It started to feel less supportive and more like a firm mattress. Dreams were absolutely amazing with the comfort guarantee and even though it ended during lockdown they honoured the replacement and we have now replaced with a Tempur Cloud. Thank you to Dreams customer service for your quick response and no quibble replacement . A great experience and would have no hesitation to purchase from Dreams again.

Excellent experience A few weeks ago I bought a Therapur Actigel Glacier 3600 mattress and was really impressed with Dreams Blackburn branch. Sadly I have really struggled with this mattress due to long standing back problem however have to note hence reason for 5 stars the overall quality of this mattress is excellent. So we popped in and had a chat with the manager Inny who offered superb advice and I arranged to go in and spend time trying different mattresses. We went back to the Blackburn branch and Sully helped us throughout the morning giving advice on a variety of mattresses that finally enabled us to choose a new mattress that met my needs. A comfort exchange was arranged and agreed the next day along with a delivery and collection date. Massive big thank you to Inny, Sully and all the staff at the Blackburn branch for going above and beyond. Would certainly recommend

Was hesitant to purchase such a pricey mattress as i tend to settle for the cheaper option of things to save money. But due to me ticking all of the boxes of the types of physical pains a quality mattress can help alleviate, I managed to convince myself that this was one area where i should go cheap. And i dont regret that decision whatsoever. I tend to wake up in the middle of the night to go to the toilet, but there have even been times where im so comfortable or there is so little pressure or strain on my bladder, that i can go straight back to sleep and get a full nights rest. I wake up well rested despite my physically demanding routine and spring up from the bed as soon as my alarm goes off. Although, admittedly, that was a bit difficult to do the first few nights due to how comfortable it is. Overall, I will no doubt be back to purchase one of these in 8-10 years time.

At our appointed time went to DREAMS IN Derby and met a very pleasant and knowledgeable staff member, Joanne who after taking our sleeping profile showed us a number of beds for us to look at. Should just say, before were came we felt a little uneasy about our security re Covid. We needn't have been, everything was so clean and wherever we went someone was spraying behind us. We decided on the Therapur 3200 Mattress, Just firm enough but with the topping "pillow" of 4cm Gell foam, my wife and I agreed it was the most comfortable we had tried, so we ordered it. It came a week later on time, but in the middle of a cloudburst. The 2 delivery guys, without being asked to, did very well by putting shoe protectors on once inside our front door, and no problem. We have had the mattress now for 2 weeks and it's fabulous, just firm enough and the top is cool.

Must admit im slightly disappointed with the mattress. Theres been a dip it in since the first night! I assumed the gel would reshape once I got up on the first morning, but nope still there. Theres also a slight bulge on the side where i sit to take my slippers off, get in etc. Thats what I'd expect after 2 years, not 2 weeks! It also smells. Not an offensive smell, just new plastic smell, but it gets a bit much after a while and woke up with a headache the first few days. Still got a slight whiff now after 2 weeks, but not as bad. Also, surprisingly heavy - need a second person to help turn it. There feels like theres metal rods around the bottom edges, so trying to pull the corner back to get the sheet on isnt wasy! Overall it is comfy and im sleeping better. Just disappointed with the "wear & tear" showing straight away considering how much it costs!!

Our new mattress arrived a week ago I spent the day going up laying on it & it felt cold & not as soft as the one in store, certainly not a cloud feeling. When my hub got back, I said I don't like it & not paying all that money for that ! Anyway after the 1st morn we both said I don't feel so stiff & I had to change my thermal pj's as I got too hot. Roll on 1 wk OMG we never realised a mattress would make such a difference to your life, our knees, back stiff joints have all disappeared. After sitting on sofa it was slow getting up thanks to stiff joints now no problem straight up ! I think it prob takes a wk to break it in as last night I got in & it felt more soft & cosy, gotta turn it today to break the other end in now ha ha. I never do reviews but I can honestly say this is worth every penny for our bodies to feel our age again !

My partner and I had been suffering with poor sleep for years on our old mattress, but thanks to our new one the only issue is not wanting to get out of bed! This mattress is actually unbelievable, I have never slept so deeply and comfortably every single night. The mattress has a cool gel layer on top so you still get the comfort of memory foam but without feeling like youre sinking or overheating. It gives fantastic full body support, but particularly for my back which Ive always suffered with on our old mattress. Finally, the staff in Dreams were really friendly, helpful and knowledgeable. We had no idea what we actually needed in a mattress so used the sleepmatch machine to pick the best for our individual needs - to say Im pleasantly surprised with how well it worked is an understatement.

We brought this mattress back in March but due to the issue's with Covid-19 we waited until June for its delivery. All I can say is that it was well worth the wait!! This is without doubt one of, if not the most comfortable mattresses I have ever slept on. It is total luxury! I used to spend a lot of time in hotels in the US and always marvelled at the beds in most of the places I stayed. This mattress is even more comfortable than the ones I used to look forward to sleeping on when I was away. It gives fantastic support, whilst feeling soft and luxurious. From the moment you lay down on it you are in a special place and just know you are in for a goods night sleep. I wake feeling refreshed, relaxed and ready for the day. A fantastic investment.

Questions and Answers About The TheraPur ActiGel® Glacier 3600 Mattress

Prospective customers had the following questions about the product

Ricky 79
How long after delivery and unpacking can I sleep on my new mattress

Answer: When your mattress is delivered, make sure the room is well ventilated for a few hours before you dress your mattress and sleep on it. Mattresses with natural or foam fillings may have a slight odour, which is totally normal and completely harmless. If you regularly loosen your bedding to help air circulate, this odour should disappear after 14 days.If youve purchased a rolled mattress, please allow up to 48 hours for the mattress to fully unroll and expand to its specified size.Thanks,

Can you use a mattress protector with this bed? If so which is best so you still get the benefits of the cooling gel.

Answer: We would recommend using a mattress protector as this will help to keep your new mattress clean and hygienic, helping to prolong its life. In the range of mattress protectors we offer a TheraPur Cool mattress protector, this is faced with 100% cotton for natural breathability and is filled with unique Quadfill fibres which are both breathable and encourage temperature regulation. As a result, this will help keep the cooling benefits of the gel.

CAN YOU USE AN UNDER ELECTRIC BLANKET WITH THIS MATTRESS

Answer: Electric blankets can be used with all the mattresses however we do not recommend that they are placed directly on the mattress surface. In addition, using an electric blanket may alter the comfort grade of the mattress depending on the mattress type.We also recommend following all guidelines and instructions specified by the manufacturer of your electric blanket.

What is difference and benefits between zipped and not zipped mattresses?

Answer: The difference between a zipped and non zipped mattress is that one mattress is a whole complete mattress and the other can be joined/separated by a zip.The main purpose for the zip it to allow the mattress to be separated for either allowing ease of maneuvering the mattress into a property or to have the option to split the mattress into separate. beds.

Does this mattress bend at all worried about getting it up my windy stairs

Answer: All mattresses can bend slightly but we would not bending enough to get up windy stairs. We would recommend buying a Zip & Link mattress instead which can be a King or Super King and splits in half so that the delivery service crews can take the mattress up tight stairwells.

What are the zipped and unzipped options please..I dont understand what is zipped/unzipped. Thank you

Answer: The Zipped option is available on the king and super king sizes to assist when manoeuvring the mattress into your property as they cannot be bent.The mattress would be in two sections and would be able to be zipped together to make one full size mattress.Many thanks

I know Sleepeezee and therapur are the same company. Can you tell me if the sleepeezee Poise 3200 the same as this type please?

Answer: Yes, Sleepeezee do manufacture the TheraPur range.The Response 3200 has very different fillings including the exclusive ActiGel foam and a different ActiCool cover compared to the Poise 3200 so they are not the same product.

Which mattress protector for this bed as the one provided doesn't fit the bed properly and makes the bed uncomfortable (bed feels more comfortable without the protector) but is required for the bedplan insurance

Answer: Apologies for the issues you are having. Any mattress protector should fit so it's purely based off personal preference. Please do get in touch with the customer service team also, as they will be well-placed to advise further. Thanks, Dreams.

An interested buyer
Hi. Your FAQ says your guarantees are from 1 to 10 years.. Why does this mattress being such an expensive item only have a 1 year guarantee.. And going by some of the bad reviews on this mattress such a small guarantee is very off putting

Answer: Our mattress guarantees vary depending on the mattress brand.This mattress has a standard one year guarantee, however you can purchase an additional 8 year guarantee on the mattress for peace of mind.
