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. Review: So cozy - If a like a soft bed this is for you. It’s very luxurious looking when unpacked and plumps the bed up. Great price. ## Features - DEEPER SLEEP: Sink into deeper sleep with ultimate cushioned comfort.

The product description is incorrect, please scroll further down to the section From the Manufacturer. This section has the correct information and i will have the Amazon team remove the product description section and replace it with the correct information. I hope this helps and answers your question. Kind regards, Customer Service Team **Q: how thick is the topper?** A: It is 5 centimetres and very comfortable Best Buy ever ## Customer Reviews ### ⭐⭐⭐⭐⭐ 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.
