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
- TEMPERATURE CONTROL: The additional layer of REVO cooling foam makes this mattress the perfect choice for those who tend to have a higher body temperature when sleeping. Providing up to 30 times more airflow than conventional memory foam, this specialist open-cell foam prevents overheating and helps you to regulate an ambient sleeping temperature.
- HYGIENIC SLEEP: A breathable mesh border surrounds the topmost layer of this mattress, increasing ventilation for greater free airflow. This helps to regulate temperature and prevent moisture build-up, maintaining the quality of your mattress and improving your quality of sleep.
- 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.

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.
Returns
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.
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.

We are really pleased with this mattress as it gives just the right amount of support. On the downside, it is very heavy and tried to knock me over when I undid the plastic wrapping ..
Mary Daggitt –
Good value and very comfortable!!
David –
Was really cautious about buying a mattress online but needn’t have been. After some negotiation with 3 flights of stairs a cardboard box and the world’s largest vacuum sealed bag (all by myself) and after a couple of day’s, I can honestly say. WOW. Best night’s sleep I’ve had in ages. Although for me it could be just a little bit firmer and there is a smell when you first open the mattress that is pretty unpleasant but after a couple of day’s in a well ventilated room it disappeared. It’s a great mattress at a great price. Highly recommended.
Ciara –
Once unrolled it took several days to really feel like it had bounced back properly. Lovely firm mattress, perhaps a bit firmer and deeper than I expected so very luxurious feel. The other half likes it and when he gets up during the night I no longer feel him getting out of bed, that’s how supportive this mattress is. Very happy with this for the price. Much better than my previous, more expensive, mattress.
Maggie Linton –
Got this mattress for my daughter as a present and she loves it. It’s very comfortable and time will tell on how long it lasts, but so far it’s great and I would definitely recommend this mattress.
Mick –
I’m quite heavy guy and laid on it and felt myself relaxed and comfortable. Would recommend it .
Lizzie Wood –
I suffer with back pain and joint pain so haven’t been able to stay in bed for more than 3/4 hours at a time as too painful. Since having this mattress I sleep so much better in fact I never want to get up now. So pleased with it and great value. Thank you.
Issy –
Bought this for my son. He loves it and I love it as well. I wish I could buy it for myself but unfortunately I bought another mattress for me at the beginning of the year so I can’t. Best mattress ever!
Theo Rounding –
This really is worth every penny! Comes rolled up which makes it easy to get up the stairs, easy to unpackage (just be careful not to cut the mattress itself when removing the packaging), nice medium feel, supportive and super speedy delivery. Everything you want from a new mattress. Happy customer!
Phil –
Can’t fault it…exceeded my expectations from a rolled mattress.
Lisa –
The foam top of this mattress is just lovely to sleep on, it’s supportive but also helps keep my body temperature down which I do struggle with due to a health condition.
As a wheelchair user I suffer from back pain from sitting all day and whilst I enjoyed a previous full memory foam mattress in the past, my back didn’t! It was too soft, this is a happy middle ground for me personally. It’s a medium firmness imo so not too hard but the springs help give it support whilst the foam is super soft for a good nights sleep
Jane Lloyd –
Bought for my new lodger who says it is very comfortable. Placed on a divan base with drawers & as it is quite deep if you are short you may need a step lol.
geoffrey dickinson –
Great mattress not to firm or soft
Rodjer Rabit –
As described and super comfortable. Could be firmer for some, but it’s just right for me.
I was suffering from neck ache each morning till I slept on this baby!
Liv Houseman –
I’m honestly blown away by the quality of my new mattress for the price I paid. I’ve been sleeping on it for 2 weeks now and have never slept better!!
Robert Grange –
Couldn’t be more happy with this mattress, great feel to it at a great price and value for money
Mark Shaw –
Decent quality mattress, reasonably firm, not so stiff around the edges so don’t get to close or you will fall out, doesn’t cover this in the star rating descriptions, ok item
Mr G J Little –
Really comfortable mattress and definitely value for money – it’s not too firm, I would say about a medium, and the memory foam layer does seem to keep me cool at night.
John Why –
Can feel the springs around the sides a little. The sides are not reinforced so it dips a bit when you sit on it. Laying on it is perfect, I’ve only had good sleep since it arrived.
Removal of old mattress was no problem and the guys were very polite
Jane. R –
I took a bit of a risk as I had never heard of this company, the mattress is pretty decent to lie on and from the first night it seemed okay, I don’t sleep well anyway so my lack of sleep is probably nothing to do with the mattress. My only one concern is that the springs are very obvious on the sides, you can feel them quite clearly, there is no padding around them. The mattress edges are very soft, I can’t detect any support on the edges. Overall I think it’s okay as I got it on offer, I don’t know how well it will last though.
Nolan Collins –
For context I’m 6’5″ and 275lbs. I love this mattress. Soft but supportive and I sleep better than I have the past 2 years. A new mattress was overdue and this was money well spent. I even got one for my daughter!
adding to original comment. after about 5 weeks I noticed a section of the bed had sunk. Tried contacting the company with no reply so far.
David J. Mccarlie –
I have to say it is very comfortable. You don’t seem to realise how uncomfortable your old mattress was. It’s a hybrid mattress with springs and memory foam so you would expect a very comfortable mattess – and it’s made in Britain.
The mattress only has one way up but you are advised to swap top and bottom regularly. I was very surprised that there were no handles on the side of the mattress, which would have made things easier when you change the mattess round.
Deb Cornford –
I have waited two weeks after receiving my Summerby mattress before writing this review!
I was sleeping badly, had neck and back pain with my Silentnight miracoil mattress!
Read the positive reviews about the Summerby mattress and decided to order one!
It arrived within 3 days and it was MUCH heavier than I thought and required two people to get it up the stairs!
I waited 24 hours before sleeping on it as suggested in the leaflet delivered with the mattress!
I slept right through the night on my first night and woke up with no aches and pains! I can’t explain how delighted I am! I’ve continued to sleep soundly since!
It’s true that the edges of the mattress are very soft but I bought this to sleep on not to sit on!!!
I can’t recommend it enough!
Yours very happily! Deb

Summreby sleep no5 mattress – Great product, waking up fresh.
wullie –
No longer getting early morning aches. Very supportive in the right places.
N MacLennan –
Have had for about 1.5 years now, is very comfortable and we get a very good night’s sleep so fine in that regard. As others have said not much support on the edges but we only really notice this if actually sitting on the edge.
Raymond Pierce –
This mattress relieved the back pain that I was suffering from it is semi firm as I asked for. The customer service at Summerby is excellent and very quick. The delivery and haul away service was on time and only took minutes. 👍
Fiona Allan –
Comfy, Best sleep I’ve had in almost 2years!
ANDREW AXFORD –
