- Reviewed in the United Kingdom on 10 May 2024Arrived promptly and well packaged. Came with great info on how to care for the mattress. I searched for a while before finally decided on this mattress and I’m so glad i did. It’s so so comfortable! It’s not too soft and not too hard - firm but very comfortable with good support. Added bonus is the affordable price, and when I bought it was a further 20 percent off. Don’t delay-buy it!
- Reviewed in the United Kingdom on 30 April 2024At the price paid, it wasn't expected to be that highest quality mattress, more just a backup mattress for the guest room which would only be used a couple of times a year. The mattress was very simple and easy to setup, coming very neatly packaged in a small box. Once opened the removal of the vacuum packaging allowed the mattress to take its full form and we were pretty impressed with the quality of materials.
We left it a couple of hours and took a lay down and it was already very comfortable and soft. The combination of memory foam and gel memory foam give a very comfortable nights sleep and the price and value for money is really hard to beat. It was way better than our expectations and definitely a bargain at the price we paid.

- Reviewed in the United Kingdom on 30 June 2024Very impressed with this mattress, so comfortable, looks great, excellent price. Will never go back to springs again
- Reviewed in the United Kingdom on 1 August 2024The product came well packaged. When opening the box I wondered how the got it in such a small box. When unravelled the mattress expanded in a few hours and I was able to sleep on it the same night. It was slightly thinner than my previous mattress but still a good thickness. As I have problems with my back the mattress is perfect it is firm and the materials was soft to the touch. It fit perfectly on my previous base and smelled new and fresh. It is very versatile as it is soft to sit on but firm to sleep on. Is a very good buy and definitely worth the money.

- Reviewed in the United Kingdom on 21 August 2024the mattress arrived quickly and as described. It is very firm, which I prefer. Comfort is a very personal thing, so you may read reviews saying that it's hard. It may be hard for them, whereas I would describe this as firm. I would say that this is excellent value for the price I paid.
- Reviewed in the United Kingdom on 9 April 2025Would not inflate I ended up having to get my money back, really really disappointed in this product 😕
On a positive note the customer service I received after the fact was brilliant
- Reviewed in the United Kingdom on 27 July 2023When i opened the box i had the same issues as other buyers; the mattress was complete flat with no shape and unable for someone to sleep on it. I read articles online about compressed mattresses and i thought to give it a chance before returning it. It took 4 days to get its full shape. Overall i m really pleased with its firmness and the quality. I wish they had it in double size as well to get another one for my other bed. Very happy with it!
- Reviewed in the United Kingdom on 26 February 2025It's comfortable
