## Description

wowttrelax Single Mattress 3ft, 8 Inch Single Memory Foam Mattress, Medium Firm with Soft Fabric Fire Resistant Barrier, Removable cover single bed mattress 90x190x20cm : desertcart.co.uk: Home & Kitchen

Review: Comfortable small double mattress and great value for money - I bought this Wowttrelax small double memory foam mattress (120x190x20) for a 4ft bed and have been very happy with it. It arrived rolled and vacuum packed, was easy to move into the room, and expanded to its full size much quicker than I expected. After airing it out, there was very little smell and it was ready to use. The comfort level is a nice medium – supportive without feeling too hard. The memory foam gently contours to the body, which helps relieve pressure on shoulders and hips, and I’ve been sleeping much more comfortably since switching to this mattress. It feels stable and doesn’t sag at the edges, and you don’t get that “rolling together” feeling when someone else is on the bed. The soft fabric cover is a bonus and the fact that it’s removable makes it easy to keep clean. For the price, the overall quality is excellent and it feels far more expensive than it is. If you’re looking for a comfortable, space-saving small double mattress that’s easy to set up and sleep on, I’d definitely recommend this one.
Review: wowttrelax Double Mattress (Memory form) - ⭐️⭐️⭐️⭐️⭐️ Comfortable and Supportive Mattress I’m really impressed with this mattress! It strikes the perfect balance between comfort and support — soft enough to sink into, but firm enough to keep my back feeling great. I’ve been sleeping much better since getting it, and I wake up feeling refreshed instead of sore. The quality is excellent, and it feels like it’s built to last. Definitely worth the purchase!

### ⭐⭐⭐⭐ A 5ft mattress
*by G***D on 9 April 2025*

This product came last week and was well packed but slightly battered and left in garden not porch provided but it unpacked and inflated very well in less than 48 hrs and fitted bed great and is very firm but extremely comfortable and you don't move about my last mattress was 30cm and this is 20 dept so a bit of height adjustment but I'm very happy with this I've had back problems with last mattress but don't feel it with this one I probably would like my next mattress to be 25cm depth and a little less firm slightly softer but at moment I'm totally enjoying this mattress it's great value for money and great quality so a great buy thanks
