Pros & Cons

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 a decade 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.

Testing Team Takeaways

To test the TheraPur ActiGel® Glacier 3800 Combination Mattress we have people from our testing team take a closer look at the mattress and form their own opinions. Below is their observations.

James Klein

Senior Product Testing Manager

Boasting a unique mix of advanced gel technology and pocket springs, the TheraPur ActiGel® Glacier 3600 Combination Mattress was certainly an intriguing product to trial. As a combination sleeper with a considerable weight, I found the medium firmness of the mattress not only comfortable but also supportive – two features that often seem to be at odds in most mattresses. The ActiGel® foam, paired with the mattress's ActiCool fabric, granted me the blessing of a cool, undisturbed sleep, a welcomed change for someone who struggles with being too warm at night. However, the mattress's pillow-top cover presented a bit of a challenge when applying sheets, though its comfort value made up for the minor inconvenience. All in all, though the Glacier 3600 was a joy to trial, from a weight and sleeping position perspective, I wouldn't say it hit all the right notes - a firmer mattress might be ideal for those with my physical parameters.

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 3800 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.

Our new mattress is incredibly comfortable, not as cool as we expected due to the waterproof mattress protector required to keep the insurance cover valid but after nipping into Dreams and purchasing a Therapur cooling mattress protector we're hoping to change this. After our first week on the mattress it has noticeable indents where we lay in the top gel layer even though the air the bed throughout the day, but have been assured that this is due to settlement but if it continues to let them know, so we're happy customers. Every night now is pure joy as we're both getting a good night's sleep and waking in the morning without the aching joints we suffered previously. So far we are really happy with the purchase.

My self and my husband brought this new mattress along with our new bed it is just what we needed this comfort is beautiful especially with the slip disc surgery my husband has had , the staff were very helpful and helped us to choose the correct bed for ourselves, the lovely man even helped to entertain our little boy I cant quite remember his name but I would 100% recommend shopping from dreams, the 2 lovely men also helped to assemble the bed once it arrived and how lovely they were chatting to my children about how one day they may be a builder , well done dream team.

Having had the chance to try various types of mattress in store on a flat bed, I was relieved to find that this one was just as comfortable and supportive when used on my adjustable bed. Although I have a serious spinal condition, this mattress has already proved itself in the few weeks I have been using it. It has resulted in much longer, more comfortable, periods of sleeps than I experienced with my previous mattress which did not have the ActiGel layer. Certainly a worth-while buy.

Oh my goodness, if i could give this mattress more stars, i would! It is heavenly. It is so comfortable, i was amazed. Its well made and i sleep well every night. This mattress was recommended to me by the sales assistant as I'm an all round sleeper - back, front, sides. She was spot on! I look forward to going to bed every night! I fully recommend this mattress.

This mattress is the best thing we have put in our new home. I am a very bad sleeper, take ages to fall asleep and move a lot. Now I fall asleep within minutes! My constant moving used to wake my partner up all throughout the night but since we bought this mattress, the motion isolation is second to none. Have never slept better in my life

Ive struggled with back pain for a while since having my baby, but since Ive been sleeping on this mattress my pains in the middle of my back have totally gone. I purchased this mattress with the TheraPur pillows and I would totally recommend if you want a better night sleep. So comfortable and well worth the money.

I tried several mattresses before I chose this one, which is the one I decided on as it is perfect for me specifically regarding comfort even during movement. I have spinal issues & this adjusts automatically in the most comfortable way to my posture & needs, making satisfying sleep possible.

Questions and Answers About The TheraPur ActiGel® Glacier 3800 Combination Mattress

Prospective customers had the following questions about the product

Verified Reviewer

Are there any common concerns from customer reviews regarding dips and durability issues over time?

Answer: There have been a few customers mentioning durability issues regarding dips forming in the mattress after continuous use and a high ridge appearing in the middle. However, maintainence, regular rotation and the weight of the user can impact the lifespan and performance of any mattress. The 10-year guarantee offered on this product provides assurance on the product's quality and long term usability.

Verified Buyer

Is the edge support effective in increasing the sleep space?

Answer: From the feedback received, the superior edge support of this mattress is highly appreciated by users. The benefit of having supportive foam around the border is twofold: one, it potentially increases your sleep area as you can utilise the entire surface of the mattress without fear of rolling off and two, it provides a supportive feel when you sit on the edge of the mattress.

Customer

Is the cooling ActiGel foam effective in maintaining an optimal sleep temperature?

Answer: Some customers have noted that the cooling effect of the ActiGel foam is noticeable, making it effective in keeping them comfortable throughout the night. However, there have been instances where the usage of a mattress protector may reduce the cooling effect. It's best to choose a breathable protector to maximise the benefits of the cooling foam. Thanks, Aaqib

Taff1

What are customers saying about the firmness of this mattress?

Answer: The mattress is described as having a medium comfort grade. Based on customer reviews, it has been well-received overall for its optimal balance between comfort and support. However, some customers have described it as slightly firmer than expected, so it may take a bit of adjustment if you're used to a softer mattress.

Mrs HTomkins

Given the hypoallergenic finish, is this mattress ideal for individuals with allergies?

Answer: Yes, due to the hypoallergenic finish, the TheraPur ActiGel Glacier 3800 Combination Mattress is suitable for people with allergies. The finish helps to prevent allergenic reactions caused by dust mites and other allergens that can be found in a mattress over time.

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,

Gotc

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

PipPipsson

Do you have a weight limit for this mattress?

Answer: Recommend max weight 18 stone (114kg) per user. Regular rotation/flipping will help distribute any settlement and aid mattress recovery, extending the life of the mattress. Please follow the mattresses care guide. Many thanks,

Mattress is 4 weeks old and rotated twice weekly. as advised by Home Serve. Body dips persist. Will these go or is it a fault with the mattress? Although comfortable will these dips get worse? We are not overweight.

What Makes The TheraPur ActiGel® Glacier 3800 Combination Mattress Great?

We've expanded on the specifications of the product to better help you understand it's benefits.

Medium comfort grade

Medium tension mattresses are suitable for the vast majority of people as they are not too soft, nor too firm. This firmness can offer a good amount of back and neck support while still being soft enough to prove suitable for side sleepers. The key benefit for this type of layer is that it's sort of a "one size fits all" approach that gives your body the contouring and support necessary while remaining soft and squishy.

Fully hypoallergenic finish

The presence of a fully hypoallergenic finish ensures relief from potential irritations or allergies—a bonus for individuals who might find themselves susceptible to such reactions. Furthermore, this trait bears an implication: by warding off allergens, the mattress effectively encourages a healthier, cleaner sleeping environment, contributing to better overall well-being.

Quilted and layered with cooling ActiGel® foam

The introduction of a quilting technique, incorporating advanced ActiGel® foam, promises improved breathability and temperature regulation during sleep hours. This considered design allows for enhanced comfort, making every sleep experience feel luxuriously refreshing, while also ensuring the longevity of the product due to its robust structure.

Rest easy with a 10-year guarantee

A 10 year guarantee/warranty goes far beyond industry norms and gives additional confidence in the product. Industry standards typically see the mandatory minimum 1 year being the most common with 5 year being rarer and 10 years being particularly uncommon, especially since the average mattress is replaced after 7 years.

Knitted ActiCool® cover is instantly cooling

Being shrouded with an ActiCool® cover, one can anticipate a refreshing sleep experience. Especially in those warmer months, the cooling attribute of this cover plays a pivotal role, making it a practical choice for individuals prone to night-time overheating.

Single-sided

Single sided means only one side is comfy. Positives are you only need to rotate the mattress occassionaly rather than the more cumbersome rotate and flip. Downside is the lifespan of the product may suffer as a result, only marginal, but worth mentioning.

Bouncy PurFibre® adds comfort and support

With a PurFibre® layer, one can enjoy a refreshing sleep owing to the amalgamation of comfort and support. It remarkably enhances the sleep quality by maintaining an optimum balance of firmness and softness.

Comes with our 100-Night Comfort Guarantee

This can provide some peace of mind to the consumer, as it allows them to test the mattress in the comfort of their own home and make sure it's the right fit for their sleeping preferences and needs.

Made in the UK

These are made and manufactured in the UK, meaning that they all meet the same exceptional quality and durability that we expect from genuine UK manufacturing.
