Customers Say
Lightweight duvet with a soft cotton cover, ideal for summer and warmer months. Comfortable, breathable, and washable, but some find it too thin or have issues with filling shifting. Good quality for the price.

Seems to be a good duvet
It's becoming a rare beast to find a polyester duvet with a cotton cover and at a reasonable price. Plus a 5 year guarantee so you expect it to be long lasting. It's quite squished in it's packaging so gave it a good shake and left it overnight. It's a little flatter than the one it's replacing and wonder if this is because it's recycled polyester. This wasn't very clear in the description and I am not a fan of recycled polyester so time will tell if this stands up to quality. So far it is fine.

Rubbish
Opened the wrapping on it to find the duvet filling falling out. One side of the duvet hasn’t been stitched at all.

Excellent for the task
I bought this as I felt it would be suitable. A 10.5 tog is too heavy for the summer. I’ve got this on my bed and I’m pleased with it.

Summer duvet with cotton cover
I bought this duvet for summer so haven’t used it yet. However what attracted me to this duvet is its cover which is made of pure cotton. I wanted to buy a king size duvet but it’s sold out so I bought the double size instead. I hope it’ll be good.
