Smart Wash & Dry Anti Allergy 4.5 Tog Duvet

Product code: T354640D

A 4.5-tog rating makes this duvet ideal for warmer nights. Part of the Smart Wash & Dry collection (formerly Supremely Washable), it's ideal for busy households, with quick-dry technology for fast and easy laundry turnarounds. It also features an anti-allergy innovation, scientifically proven to reduce dust mite allergies, making it a great choice for a fresher sleep environment.

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.

Good quality

Yes, I recommend this

During the recent heatwave the 13.5 tog duvet proved to be much too much so I bought this one. It's light and comfortable.

Fine but!

Yes, I recommend this

So far very good. But why on a really soft piece of bedding is there a very sharp stiff label at one side?

Summer Duvet

No, I don't recommend this

This is my first ever review. I bought this duvet for summer to replace my old one which was 4.5 tog. I can’t use it as it is so warm, it’s such a waste of money as you can’t return duvets. I will continue with my old one this summer. I won’t buy another duvet from Marks.
