## Description

Product Description LOOKING FOR A MORE NATURAL AND SUSTAINABLE SLEEP? At Slumberdown, we believe in better sleep for everybody. That's why we've created a range of wonderful duvets made with 100% British wool, which are comfy all year round. Drift off naturally and sleep soundly knowing you've chosen a duvet that's good to you and the planet too. Wool bedding is ideal for keeping you cool when warm or cosy when cold. This Wonderful Wool duvet is made using 100% British Wool from British farmers, encased in a rich cotton cover. Naturally temperature regulating, hypoallergenic and sustainable. Wool is also great for moisture control, keeping you dry during those sticky nights. As a fully renewable material, you can enjoy a perfectly comforting night’s sleep that is kind to you and the planet. WHAT MAKES WOOL SO WONDERFUL? BETTER FOR SLEEP Wool bedding has been proven to improve sleep by up to 25%, so get set for dreamier nights ahead. NATURALLY SUSTAINABLE As long as there’s grass, sheep can keep grazing, and produce a new fleece year after year. Which means wool is a wonderfully renewable material. NATURALLY COSY Wool is made up of both soft and springy fibres, so you’ll always get the support and comfort you need. 100% COTTON COVER To enhance the effects of this impressive filling, the duvet has a 100% naturally breathable cotton cover. WHAT SWEET DREAMS ARE MADE OF? A DREAMY TEMPERATURE Come rain or shine, you’ll see sheep grazing in fields across Britain. That’s because wool naturally regulates temperature and keeps them cool or cosy. Its breathable fibres circulate air when it’s hot, and lock in heat when it’s not. NO MORE SNEEZING Hypoallergenic by nature, wool bedding is ideal for anyone suffering from allergies. Unlike other materials, it won’t let dust or bed mites flourish and is averse to mould. So you can breathe easy night after night. SLEEP THROUGH NIGHT SWEATS The menopause can disrupt sleep, particularly if you’re experiencing hot flushes at night. Wool absorbs moisture when damp and releases it when dry, which means you’ll stay nice and cool. MADE IN THE UK Made from100% British wool, this duvet is handcrafted in the UK. ONE WONDERFUL DUVET. THREE WEIGHTS. LIGHTWEIGHT Choose this lightweight Wonderful Wool duvet if you prefer a duvet with lower weight and warmth – similar to a 4.5 tog. Designed to keep you cool over the summer months, so you can enjoy a blissful night’s sleep, at just the right temperature. MEDIUMWEIGHT Choose this midweight Wonderful Wool duvet if you prefer a duvet with a medium weight and level of warmth – similar to a 10.5 tog. Designed to give you a balanced comforting night's sleep all year round. HEAVYWEIGHT Choose this heavyweight Wonderful Wool duvet if you prefer a duvet with a higher weight and level of warmth – similar to a 13.5 tog. Designed to give you extra warmth in winter months for that added cosy feel so you can sleep soundly.

Review: Once you try wool you won't go back - The things we do for our loved ones, right? Here I am, a happily married man plodding his way through life and kipping each night under a comfortable duvet when my wife says "we should get a wool filled duvet". What? Why on earth would I want a wool filled duvet? I run hot during the winter for goodness sake the last thing I need is to be essentially wearing a woolen jumper to bed everyday! "Oh, but wool keeps you cool and warm" says the wife. Yes, of course it does I think... But guess what... I still buy one! I am glad I did! As I write this we've had some chilly weather in blighty and I have slept like a log, comfortable, warm but not hot and haven't woken up feeling like I've been sweating more than I do when thinking about paying the utility bills! The duvet itself has good a decent weight to it, enough to notice but not enough to feel like it is too much. There is a thickness to it which provides a great look when plumped up in a cover and feels generally well made. Our previous duvet was man-made-fiber and had moved within the cover, this is stitched in such a way that leads me to believe that shouldn't be an issue. Both my wife and I are very pleased to have swapped to a wool duvet, it warms up much quicker and offers a far better sleep then before, the best thing being that my wife, who usually runs cold, no longer feels the need to put cold feet on me to warm up - the duvet is doing it for me! The only downsides would be that, with it being a naturally filling, you will notice the smell of sheep on the duvet for a day or two, this is solved easily by airing it outside of hanging it up in a garage - personally, we weren't bother by it but some might be. The other being the noise the duvet makes, when new it can sound like a crisp packet being ruffled, again we didn't find it an issue and it never disturbed our sleep, we have found that after a week or two it has settled and put this down to the cover becoming softer over time, give it a good shake each day and it'll improve. In summary, I won't go back to another type of duvet, whilst I am yet to try this during summer temperatures, having gone back to a poly-filled duvet for a night when away for work, the different is incredible and one that is difficult to describe unless you try it yourself, you to may be as surprised as I am! I might even get an extra one for the guest bedroom for when the misses is snoring and I need some peace...
Review: Wake up to wool duvets! - A wonderfully warm though lightweight duvet, even for this tog. A lovely, cosy feel, immeasurably better than a synthetic duvet and considerably more economical than a feather/down duvet. Also, some manufacturers of feather/down duvets obtain their filling from sources where the welfare of the birds is at best questionable, but sheep-shearing is, as far as I'm aware, normal practise and healthy for the sheep. Slumberdown wool duvets are also very good value - many others are available at much higher cost but this scored top in a May 2025 Good Housekeeping survey of wool bedding, which is the main reason I chose it. I bought a brushed cotton/flannelette duvet cover for it, which adds to the cosy feel. The duvet needed airing for four or five days after opening, to air out the natural wool smell - not unpleasant, just a bit unusual, but it soon goes. Highly recommended. Thank you, Slumberdown.
