Warm & Toasty 13.5 Tog All Season 3-in-1 Duvet

Product code: T359818D

This 13.5 tog duvet from the Warm & Toasty range adapts to changing seasons year round. It combines a lightweight 4.5 tog layer perfect for summer and warmer weather with a medium-weight 9 tog section for cooler nights. Made from soft, durable materials, the innovative dual layer 3-in-1 design allows you to join both layers together during winter and colder months for maximum warmth.

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 Lightweight and Flexible Duvet Set

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

This is a great lightweight and flexible duvet set. The 7 tog is perfect for Spring and Autumn, with the 4 tog great when the nights are warm. Combine them for the deepest days of winter. The quality of the set is high and it is nice and light on the bed - not pressing down on me

Bought these two singles to give my wife and I the capacity to exactly tailor our covering to suit our different preferences. I heat up quickly, she needs extra warmth

Fantastic cosy duvet

Originally posted on marksandspencer.com (UK)

This duvet is the best duvet I’ve bought in recent years.. it’s great quality and the fact it can be used in summer simply by separating the 4.5 tog from the 9tog is an added bonus.

I have bought 2 of these , they are very warm good quality, my only criticism is that there are only snaps on 4 corners making them harder to put the covers on could do with a couple more on the sides

Lovely quality, nice and soft. They pop together and don’t come apart when they’re in the cover, you can’t tell it’s 2.

New duvet

I purchased this duvet to replace my old very heavy one. This new one still has the warmth without the weight. So cosy and can separate when we get some warmer weather.

Not what I thought!

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Initially I thought this quilt was wonderful warm and weighty it was a little awkward for me to put the cover on but after a short time the top quilt moved around and kept on bunching inside the cover.so not as good as first thought. I purchased two more for my daughters and will see what they think of them.

Lovely and plush. Great value for money. Just wish it was in a zipper bag for easy storage when not using the seasonal duvets.

A lovely Duvet!

Originally posted on marksandspencer.com (UK)

Reported the delivery to M&S as this was thrown over a gate 200 yards from my home. I received what seemed very much like an AI response. But, I got the duvet and it’s lovely. Quite heavy so it cuddles you to sleep! Would recommend.
