About this product
Transform your mattress with this generously filled topper that adds a soft, supportive layer of comfort to help you sleep more deeply every night. It's filled with plump hollowfibre and covered in soft microfibre, which creates a cosy surface that feels gentle and inviting when you slip into bed. The elasticated corner straps grip your mattress securely, so it stays perfectly in place without shifting or bunching up. It's hypoallergenic, which means it's kind to sensitive skin and doesn't include any contents likely to cause allergies, making it a reassuring choice for the whole family.
The hollowfibre filling provides gentle support that adds comfort without changing the feel of your mattress too drastically. It's machine washable and tumble dryer safe, so keeping it fresh is simple and practical for everyday life. The straps fit mattresses easily and keep everything secure throughout the night. Whether you're looking to refresh an older mattress or add extra softness to a firmer one, this topper delivers comfort and practicality you can rely on night after night.

This mattress topper is soft, comfortable, and improves mattress comfort significantly. It fits well, is good quality, and offers great value, though some find it thinner than expected and shifting on the mattress.

Perfect for zip and link beds
Bought to cover 2 single beds together (zip and link) to make a more comfortable large double bed guest bed - does exactly that. Would definitely recommend for this purpose.

Breathable and supportive mattress topper.
I recently purchased this single mattress topper to go over another thin mattress. It was perfect and improved sleep quality. It is soft, good quality and just the right thickness.

Great topper
A lovely soft topper. Thicker than I expected which is great. Washes well and keeps shape. Very comfortable and great value for money

Great for last minute guests
Bought for the sofa bed in the spare room! Great price. Small enough to store when not needed. Ideal.

Not very thick
Its soft but not as thick as expected
Bobby
Good value for money
I have found this to be soft and comfortable, a reasonable thickness washes well. The only little bug I have is that the way it fixes over the corners of the mattress does not keep it tightly in place.
Happy shopper

Hi, Dolly.
Silentnight Deep Sleep Mattress Topper - Double 836/1394
A king-size would be too large for a double, and the elastics would not fit as snugly as intended.
Thanks for using Q&A

Hello Tammy,
After checking with our supplier, they have advised for the Silentnight Deep Sleep Mattress Topper - Kingsize: For a King sized topper we recommend using a large capacity washing machine typically around 10kg drum or larger. If your home machine isn’t suitable, many customers find that local laundrettes or professional laundry services are a good option.
Thank you for using Q&A.
