## Description

Here at Slumberdown we know that there is no such thing as perfect when it comes to sleep, but we do believe that with the right bedding, it can be made better! Snoring, dribbling, sneezing- whatever it is keeping you awake at night we have bedding tailored to your needs and it is no different when it comes to our mattress toppers. Slumberdown mattress toppers are a cost effective way to help to enhance your bed and revive your mattress for a luxurious layer of comfort and support as you sleep. Our Extra Deep 10cm mattress topper is beautifully designed with a soft touch fabric and extra deep hollowfibre filling that bounces back, and thanks to the box quilt design it keeps a consistent depth throughout.

Whichever size you need it will be a perfect fit right to the end of your mattress and is secured in place by strong, durable elasticated straps so you don't need to worry about it moving around in the night. Your mattress topper is easy to keep clean too and can be washed and dried in one day as it is washing machine and tumble dryer friendly.
