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

£49.50 - £79

Colour

Size

Free standard delivery over £60

Product code: T355706D

Snuggle down for a peaceful night’s sleep with this anti-allergy duvet. It's made with BI-OME® NTL Margosa treated fabric which deters the growth of dust mites and controls odours and bacteria for freshness. This duvet separates into a 9 tog and much lighter 4.5 tog for the warmer seasons, or you can put them together for a 13.5 tog duvet to help keep you cosy on those cold winter nights. It's like having three duvets in one.

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.

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

I’ve only had to use the 9Tog part of the duvet set and it’s fabulous. Soft and warm - ideal for cold autumn nights.

As soft as down and curls around me as I sleep

Yes, I recommend this

I bought this specifically as I realised that I had developed allergies, especially to dust mites, and this seemed to fit the bill. BUT not only is it anti-allergy, it's also SO soft and it curls around me just like a down quilt does (not stiff like so many quilts with artificial fillings are). Have had a couple of wonderful sleeps since getting it and only wish it had been available years ago. Worth the money and more.

Always good quality!

No, I don't recommend this

Nothing but quality from M&S as always; the nice thing about this duvet insert is that the ‘tog’ can be changed, as it is a 2-in-1

Good value for money

Yes, I recommend this

Our new Anti-allergy Plus All-seasons duvet has proved very comfortable and warm. We bought it to replace a very old one and its noticeable how much lighter and comfortable it is. By way of comparison, when staying with relatives with down duvets, I can honestly say its just as light and effective. Its price is also considerably more affordable then many direct competitors.

Great Duvet and Excellent Value

Yes, I recommend this

Bought it for my aunt as a long overdue replacement. She loved it and it made a huge difference keeping her warmer at night on top of being lighter than her old feather duvet as well.

Very happy with it

Yes, I recommend this

Really pleased with the product. The material is lovely and soft and doesn’t rustle like some duvets I’ve found. Really pleased with the quality. The last M&S duvet we had was missing stitching that kept the filling in place so it ended up bunch up in a corner but both layers of this have the stitching.

Surprisingly warm and light

Yes, I recommend this

Initially I thought this may not be very warm as it is so much lighter than my own duvet, also feels 'empty' compared to my dense duvet. However, as someone who is always cold and goes to bed with several hot water bottles I was very surprised to find this duvet so much warmer than my old one. In fact I was too warm at times. It is January so I am using the duvets together but considering both my old duvet and this one is 13.5 tog im very surprised how much warmer this one is. I had considered looking for 15 tog as I was starting to feel the cold in my old same tog duvet.....so glad I didn't now. It is very snuggly too. My only gripe in that it makes it hard to get out of in the morning 😔
