Anti Allergy Plus 13.5 All Seasons Tog 3-in-1 Duvet

Product code: T355706D

This anti-allergy duvet offers comfort with a clever 3-in-1 design. It's made with BI-OME® NTL Margosa treated polyester which deters dust mites and controls odours for freshness, keeping you free from allergens. The innovative system separates into a medium warmth layer and lighter weight layer for warmer weather, or combines to create extra cosy warmth for winter, giving you year-round comfort with different tog ratings from the anti allergy collection for every season.

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. Our All Season duvets can be used all year round, with a lighter tog for the summer, a heavier tog for the inbetween months, or join them together to be warm all winter.

A warm cosy duvet, Im now having a better nights sleep with the weighted feeling. So glad I replaced from a lighter one and blanket. Looking forward to using it through the year.

Good quality, good price.

Yes, I recommend this

This was to replace a feather 13.5 tog duvet. I thought I wouldn't like it as much as the feather one but I'm pleasantly surprised. It is fairly heavy as a 13.5 tog when the 2 duvets are pressed together but I quite like that when it's cold. It will be easier to put in the washing machine now I can separate the 2, I always had to take my feather one to the laundrette. The bed looks properly "made" now because the feather one always looked uneven and bumpy whereas this one is nice and flat.

Wanted a bigger duvet for our king size bed so we get no cold spots. We only have the 9.5 tog on the bed but it's super cosy.

Our favourite cloud duvet!

Yes, I recommend this

This duvet is absolute perfection for A/W it’s like sleeping in a cloud, such a warm dreamy hug sleep experience. It keeps us so warm & toasty that we don’t want to move from being wrapped up in the duvet. The quality is brilliant, and love that you have the option to use just the 4 tog during summer but can easily attach both together to make a dreamy 13 tog option for winter. The filling is so lovely and light, it’s easy to wash & dries like magic. Absolutely top quality in my opinion thank you m&s
