## Description

Is your old mattress keeping you hot and bothered? Extra cosy and naturally temperature regulating, our Wonderful Wool Mattress Toppers are the perfect way to enhance your mattress with an extra layer of hypoallergenic, natural comfort. The 100% British wool in our toppers keeps you comfortable by wicking moisture away from your skin, which is then released into the air, keeping you cool and comfortable when it’s warm. When the nights are cooler, wool fibres trap warmth in ensuring you stay extra cosy, without overheating. Wool is naturally hypoallergenic, making it a great option for anyone who suffers with allergies or sensitive skin. Unlike other materials, wools natural properties prevent common irritants like bed mites and mould from thriving, helping you get a healthier and more restful night’s sleep. Natural sleep system: To maximise the benefits of wool on your sleep, we suggest using a complete wool bedding setup, including duvet, pillow and mattress topper. · Our range of wool mattress toppers are made with 100% British Wool supplied from farmers across Great Britain. The easy fit elasticated straps mean our Wonderful Wool range of toppers will fit almost all bed sizes. Sheep wool is completely biodegradable and releases essential nutrients back into the soil as it breaks down. We recommend you allow your wool duvet to air for 24 hours before use. To allow your wool duvet to breathe and wick away moisture, use a 100% natural duvet cover. Regularly air over a clothes horse or washing line to keep it fresh and clean. The wool in our products is free from harsh chemicals and is washed in a biodegradable, bleach free detergent that’s also non-harmful to marine wildlife.

Review: Good quality natural fibre topper. - Bought to go on top of an Emma mattress, as I found the mattress made me overly warm. I'd read that having a natural fibre topper would help, and this does seem to. It does smell a little woolly, as you'd expect because it is wool! Adds a little comfort, but mostly me requirement was to help reduce overheating at night and I do think it has.
Review: Great product - Exactly as described. A great product, good fit on mattress, comfortable and cooling. I like the fact it’s easy to maintain.

## Features

- BETTER FOR SLEEP: sleeping on a wool topper is scientifically proven to give you 25% better REM sleep. If you need a good nights sleep but struggle with night sweats, hot weather or maybe the menopause then this king size mattress topper is perfect for you.
- HYPOALLERGENIC: with no added chemicals our wool king size mattress topper actively repels dust mites, mould spores and bacteria - the cause of so many allergy symptoms. It is also naturally odour resistant and fire retardant.
- THERMO-REGULATING: sheep wool is 50% better than any other fibre at wicking away moisture caused by overheating. Wool can create a personal ‘microclimate’, circulating air around each sleeper, to keep you warm (or cool) and comfortably dry. The protector is filled with 200 gsm of 100% Natural British Wool and the 'wool effect' is further enhanced with a breathable 100% cotton cover.
- MADE IN THE UK: we pride ourselves on quality that's why our mattress toppers are manufactured in Yorkshire by a family business with over 100 years experience in bedding.
- ECO FRIENDLY: wool is 100% natural, renewable and recyclable. When a sheep is sheared its fleece quickly grows back making wool a sustainable choice and and prefect to keep yourself warm this winter
