Features
- STURDY BASE: A luxurious improvement on the traditional spring system, each tempered steel coil is individually encased for a nested and breathable effect. The elevated comfort provides postural and orthopaedic support to reduce your bodily aches and pains, as well as reducing motion transfer.: A supportive memory foam layer helps align the spine to reduce pressure points for increased comfort.
- RESPONSIVE TOP: A generous layer of memory foam cleverly adjusts to the body by responding to its temperature, moulding itself to your shape for comfort that’s tailored to the individual, regardless of sleeping position. Once “remembered”, your body is lovingly cradled in place, helping to reduce tossing and turning.
- SOFT-KNIT COVER: This quilted cover is breathable and hypoallergenic, giving you improved moisture control and reducing allergy triggers. Kind to your skin, the soft fabric blends comfort and hygiene to complete your mattress perfectly.
- MADE IN THE UK: All our mattresses and toppers in the Summerby range are made on site at our home in the heart of West Yorkshire. We are a family-run business with over 30 years of experience in mattress manufacturing, promising attention and care taken in every step of the process, from design and production to packaging.

Care
Cleaning:
To preserve the good condition of your mattress, we advise using a mattress protector underneath a fitted sheet to protect from any spills and stains.
To spot-clean the mattress directly, simply wipe down the affected area with a clean, damp cloth and allow time to thoroughly dry afterwards.
Avoid using any harsh detergents or chemical cleaning products on your mattress.
Turning:
As we design our mattresses with multiple layers to maximise their support and comfort, they do not need to be turned.
However, to maintain an equal distribution of wear and tear on the top-most layer, we do recommend occasionally rotating your mattress. This should ideally be done once a week for the first month of use, and then once a month thereafter.
Shipping
Free & Easy Shipping: This mattress is compressed and shipped in a box for quick, convenient delivery and easy set-up.

What comfort-grade is this mattress?
This mattress has a medium comfort level.
How long do I have to wait to sleep on it once unrolled?
It can take up to 24 hours for the mattress to reach its full depth when first unpacked. We recommend that you do not sleep or sit on the mattress during this time to allow it to fully expand to its correct shape and size.
How deep is this mattress?
23cm
Do I need to flip my mattress?
As our mattresses are designed with multiple layers to maximise support and comfort, they do not need to be flipped.
Do I need to rotate my mattress?
People tend to sleep in the same position every night, which leaves an impression on the mattress surface. You should rotate your mattress from foot end to head end to maintain equal wear and tear. We recommend rotating your mattress once a week for the first month of use and then once a month thereafter. Rotating your mattress gives the foam layer time to recover before its next rotation.
Can I return the item?
Products can be returned to us within 14 days of delivery provided they are unused and in the original packaging. Return shipping costs must be paid for by the buyer. Summerby will not accept returns or exchanges on items that have been damaged by the buyer. For further returns information please view our Returns Policy.
Who is this mattress ideal for?
This mattress is a great option for master bedrooms and spare rooms.
Can I use any bed base or frame with my mattress?
Yes, you can use your mattress with any divan base or frame. For slatted bed frames, we recommend a gap of no more than 7cm between the slats to give your mattress the correct support it needs.

Supportive pocket springs
Pocket springs support every inch of the body and alleviate stress from high-pressure areas of the body like shoulders and hips. Because they're individually encased, the springs reduce partner disturbance - perfect for couples!



Pressure relieving memory foam
Pressure relieving memory foam compresses evenly under body weight and conforms to the body’s curves to alleviate common pressure points. Perfect for helping with aches and pains.
