Review: So comfortable. - This is a first class purchase, soft, comfortable , you sink into it at night and unlike some others it stays in place, the padding is soft but offers support, flat and comfort to the back, it makes a bad bed good. Review: Very comfortable, a good buy - I bought this after spending a night in a hotel on an unbelievably confortable bed. This mattress topper was advertised as being used by hotels, so I thought it might help with my bed. It was cheaper than memory foam, which also has a reputation for being uncomfortably hot. At first I was disappointed by how small the double bed size topper was. But actually, it fits well - just not quite to the edges - which means that I can still use my existing fitted sheets. It comes vacuum packed and very shrunk down. I followed all the instructions on fluffing it up and leaving it before use and it expanded to a decent thickness of softness. It seems to be fairly well made, with no obviously loose threads. There is elastic in the corners which holds it in place on the mattress. This has proved to be a game changer for my ageing body on my uncomfortably hard mattress. Not only that, but it's warm. Not sweaty warm, but cosy, comfortable, don't want to get out of bed, warm and comfortable. I've had the best several nights sleep for ages and feel much better as a result. I think it will fit in the washing machine as it is lightweight, compressible and should spin fairly dry, similarly to my quilt. I get the impression that my quilt is made of similar material, just less densely packed. It will probably need fluffing up again afterwards, but the stitched pockets should avoid too much clumping. I have recommended this to several of my friends because it is just so comfortable. I will probably get one for the caravan as well. Very pleased so far. ## Features - DEEPER SLEEP: Sink into deeper sleep with ultimate cushioned comfort.

I have a memory mattress but it’s harder then I thought it would be will this make it softer ?m** A: I use this on a sofa bed. There’s very little movement and has made it more comfortable at the same time. **Q: Would this be good for joining two single beds together** A: Not totally sure. Has straps on each corner to loop over a double mattress, but will possibly join two single beds together. Nice quality topper. **Q: Does this flatten and lose its depth and comfort ?** A: No, it remains very comfortable. **Q: Is this mattress topper fully washable?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ So comfortable. *by A***R on 15 May 2026* This is a first class purchase, soft, comfortable , you sink into it at night and unlike some others it stays in place, the padding is soft but offers support, flat and comfort to the back, it makes a bad bed good. ### ⭐⭐⭐⭐⭐ Very comfortable, a good buy *by G***W on 5 February 2026* I bought this after spending a night in a hotel on an unbelievably confortable bed.
