Review: Great choice! - So good! I’m so impressed by this duvet. The fact it’s three in one makes it worth it but the quality is great. It’s a lighter duvet than others but still keeps you warm when you need it and cooler in the summer.
Review: Moving with the times - Moved away from sheets and blankets and this was recommended by a friend. Very comfortable. Good thickness for both summer or winter. Stitching is fine and neutral odour. Great value for money.

### ⭐⭐⭐⭐ Good quilt but stitching could be better
*by A***R on 19 April 2026*

Perfect multi season quilt but at the moment we have only used the thin one- it’s warm enough in winter. Very light and soft but the stitching that runs the length have come unpicked at the top- probably where we pull the quilt up.
