Firmness: People who prefer a firm mattress will like this product as it provides good support for their back and helps alleviate back pain.

Comfort: A lot of customers find this mattress to be comfortable, and many claim it has improved their sleep quality.

Memory foam layer: The memory foam layer provides additional comfort and support, making the mattress feel softer while still being firm.

Good value: Customers appreciate the reasonable price point of this mattress and feel it provides good value for money.

Quality:From a manufacturer as good as Sealy, the quality and durability of the product is very high.

Limited sleep positions: The mattress is reported to be comfortable for back sleepers but not ideal for those who sleep on their side or stomach.

Feeling springs: A few customers report feeling the springs through the mattress, which can be uncomfortable and somewhat surprising given the deep layers of memory foam.

Too warm: The memory foam layer makes the mattress warmer than some would like, which can be uncomfortable for hot sleepers.

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.

Great firm mattress. You can tell the structure is high quality, judging by the material that the mattress is covered in and the useful handles on the sides to ease manouvering the product and turning it.I was a little concerned about the memory foam aspect, as previously a full memory foam mattress didn't suit my partner, it made him sweat quite a lot. However, we have had no problems with this.Overall, we have found this to be very comfortable and great value for money.

Not being able to compare, without trying loads of mattresses, you have to go with 'description and instinct'.It doesn't disappoint: it's firm, but not 'bone hard', very supportive and comfortable. I was a little concerned that the 'memory foam' top might be too warm, but I needn't have worried; it's fine. So, if like me, you prefer a firm mattress at a bargain price, then this is for you.

My former mattress was a cheap one by dreams, it was like sleeping on stones.This one on the other is another story. It's quite firm but very supportive. This is also my first memory foam mattress. I have sciatica flare ups which happen in random places and this mattress really helps me get comfy without feeling any pressure in the bad areas.I got this mattress while on offer so it was super expensive.

Firmer than I expected it to be. It is a very firm mattress. You don't sink into it. I like this and my back has been better. Feels like a quality product that will last. I was worried that I wouldn't like the memory foam but I can't really feel it, it just feels soft. Great mattress if you like a firm one ?

It has a wonderful finish, the handles on the sides make it easy to lift and move it around. The mattress is confortable and quite high, which is great ! No more squatting to seat on the bed!And the best thing is that my hip/lowerback pain are much better since using this mattress.

Firm but the memory foam creates the perfect amount of support. I always have a great nights sleep and the bed is very deep which i like as I have a low bed frame. Would certainly recommend to anyone with mild back problems. Great quality make.

It's firm but to too firm, the memory foam at the top is softer so adds a nice bit comfort. Purchased mainly to help by husbands lower back problems, this has certainly helped, he feels much better and I like it too.
