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.

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.

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.

Brand Rating

  • Overall Brand Rating
    ★★★★★
    ★★★★★
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

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.

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

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

Prospective customers had the following questions about the product

Image of the post author
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.
Image of the post author
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.

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,

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

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.

Answer: Settlement on a mattress is expected, and as long as care instructions are followed this should be fine. However if you feel this becomes excessive, we can look into this further for you.Many thanks

Weve ordered this mattress but see complaints about dipping and ridges. In reading the additional cover T&Cs they state that dipping is not covered if within limits accepted with the bed manufacturing industry. What are these? Are ridges covered?

Answer: An acceptable amount of dipping for a Pillowtop mattress is 3cm in the first 6 months, up to 5cm in 5 years. Many thanks,
