Luxury Down Alternative 4.5 Tog Duvet

Product code: T352120D

Sleep in lightweight luxury with our Luxury Down Alternative 4.5 Tog Duvet, designed for warmer seasons or naturally hot sleepers. Filled with our premium down alternative for a plush, feather-free feel, it’s encased in a smooth 180 thread count pure cotton cover for breathable comfort. The box-stitched design ensures even distribution of fill, preventing clumping and maintaining consistent warmth. Ideal for spring and summer nights, this duvet offers a soft, airy sleep experience with a touch of indulgence.

The tog rating refers to the effectiveness of the duvet to retain heat – the higher the tog, the warmer you will be when you're snuggled beneath it. A 4.5 Tog duvet is perfect for the spring and summer months when the weather is warm.

Where else would you buy your duvets?! My daughter runs hot so I switched out the winter duvet earlier than expected and this is wonderful. Lightweight, good quality and super soft!

We were looking for a good quality summer duvet and unable to have feather or down due to allergies. This one works for us, not too lightweight you loose it but cool enough. Separate pockets so it keeps even

Great quality and value for money

This is a good quality quilt. Lovely cotton cover and soft downy filling. The only criticism is that I bought it for summer use as my M&S 7.5 tog is getting too warm. I honestly don’t feel any cooler with this 4.5tog.

Lovely and soft king size duvet that replaces a similar 4.5 tog down duvet. We sleep under it perfectly.

Lightweight and well made. Bought for warmer summer months but I am using it now in March. It's cosy and warm but does not get too hot. I have not washed it yet.
