Review: Soft comfortable topper - Fitted my sealy king size bed perfectly. No smell. Turned my hard orthopaedic mattress into a soft, comfortable, warm, luxurious mattress without all the expense or bother of replacing it. Best purchase and first good night's sleep in ages following hip surgery.
Review: Very good topper - Very comfortable topper, proper memory foam, which has enough resistance to provide support but still very cosy. A decent thickness. Very little smell and it filled out quickly. Very pleased. And thank you for the owl key ring!

### ⭐⭐⭐⭐⭐ Soft comfortable topper
*by A***R on 24 December 2025*

Fitted my sealy king size bed perfectly. No smell. Turned my hard orthopaedic mattress into a soft, comfortable, warm, luxurious mattress without all the expense or bother of replacing it. Best purchase and first good night's sleep in ages following hip surgery.

### ⭐⭐⭐⭐⭐ Very good topper
*by M***S on 17 February 2026*

Very comfortable topper, proper memory foam, which has enough resistance to provide support but still very cosy. A decent thickness. Very little smell and it filled out quickly. Very pleased. And thank you for the owl key ring!

### ⭐⭐⭐⭐ Comfy with a minor flaw
*by M***H on 20 December 2025*

Very comfortable and has helped with aches from a firmer mattress. The zip for the removable cover, however, won't budge so it's not going to be easy to clean when the time comes.
