Our Mattresses


Q: Which mattress is best for me?
Our research shows some people like their mattress to be made of memory foam, and others like the feel of pocket springs, so we made the perfect version to suit everyone. Our Pocket Spring mattresses are a touch firmer than our Memory Foam mattress which is made purely from high tech memory foam and moulds to the contours of your body while you sleep.
Q: What are the mattresses made out of?
Our award winning raspberry trimmed Pocket Spring Hybrid Plus mattress is a unique combination of both memory and 2000 pocket springs for the sleeper who prefers a firmer surface with a slight spring. Our orange trimmed Pocket Spring Hybrid mattress is loaded with 1200 micro pocket springs, which individually adjust to the contours of your body while you sleep. This helps to distribute body weight and reduce the build up of pressure points.

Our mint-trimmed Next-Gen Memory Foam mattress is made purely from high tech memory foams and our Next-Gen Memory Foam Plus is a whopping 25cm of pure comfort. If you're really into the detail, explore the 'Technical Information' sections on our product pages.

Q: Will the mattresses work with all bed types?

Q: Where do you manufacture, and what safety tests are taken for the Hyde & Sleep mattress?
Our mattresses and springs are all British made, and skilfully constructed in the UK by our team of expert mattress makers.

Our manufacturer is a National Bed Federation Approved Member (2016) – having been successfully audited by EXOVA BM TRADA against the NBF’s strict code of practice which sets out criteria for ensuring processes and procedures are in place for supply chain scrutiny and compliance with regulatory requirements, including flammability, cleanliness of fillings and trade descriptions.

They were also recognised by the NBF with a highly commended award for the 2015/16 Bed Manufacturer of the Year and they have received the SEDEX/SMETA Best Practice Guidance accreditation.

All foam in the manufacture of our mattresses are CFC free and all components comply with UK fire regulations BS7177 Low hazard for domestic use - the most stringent in the industry.

Q: Why does my mattress’s zip appear to be broken?
The mattress cover does not feature a full zip as it should not be removed and is very difficult to put back on. We recommend that you do not remove the cover to wash it, but take the best possible care of your mattress by following our solutions in our Aftercare questions.

Q: Do you offer a trial period on all products? How does it work?
Oh yes, we offer a trial period of 100 nights on all mattresses. We advise that you wait at least 30 nights before initiating a return on your mattress to allow you enough time to get used to it. If before 100 nights you are still unsatisfied with the mattress for whatever reason – Hyde & Sleep will collect the mattress free of charge from your home providing that a mattress protector was used and that the mattress is not marked or soiled, You will then be issued a full refund with no hidden costs. For more information, visit our Returns & Refunds page.
Q: Do you offer any finance options?
Yes! We wanted to team up with a name you know and trust, so we're proud to work with Barclays Partner Finance. They can offer interest free credit on all purchases above £250.00. Read our Finance page thoroughly to understand how this option works.
Q: Do you have a showroom?
We sell online only, which of course, guarantees that you pay the lowest prices. Don’t forget about our 100 night rest test where you can really get to try out our mattresses and get a full refund if it is not for you.

We have three delivery options. Free Next Day Delivery is available any day between Monday - Friday, Next Day Morning Delivery guarantees it'll get to you before 10:30am for an extra charge of £25.00 and our Saturday Morning Delivery option will arrive any Saturday before noon also for an extra charge of £25.00.

If you need your order to arrive before 10:30am, try our Next Day Morning Delivery service.
Q: Can my order be left somewhere else if I am out?

Once you have placed your order, if you need to change your delivery address, you will have to supply us with the following information for security reasons:

When it arrives


Q: How do I set up my mattress? Why does it arrive in a box?
Your mattress will arrive inside a portable and compact box. We have invested in distinctive technology that vacuum seals, rolls and packs our mattresses, ensuring they are compressed into the smallest of spaces. This makes them easier to deliver, and speedy, simple and stress free to install. Refer to our introductory pack for more information, or why not watch our unboxing video? You can find it on our product pages.
Q: What size is the box?
The box is 50cm x 50cm x 105cm.
Q: Do you dispose of my old mattress?
Not yet, however we have had a lot of demand for this and we are listening to your suggestions. Watch this space!



Q: Can I use an electric blanket on my mattress?
As memory foam is heat sensitive, softening and conforming to the body shape, the use of an electric blanket will give the mattress a softer feel. When the blanket is not in use the mattress will return to its original form.
Q: Do the mattresses come with a guarantee?
Our research shows that a mattress should be changed every 10 years, so that's how long our guarantee is. That’s almost 3000 nights of peaceful sleep! We do not offer a warranty (our lawyers tell us there is a difference), but not to worry! The guarantee gives you all the protection you need.
Q: How do I clean and protect the mattresses/pillows?
Our mattress covers should not be removed for washing, as they are not designed for this. Instead use a soft, damp and clean cloth using small circular motions to clean your mattress. You may also use light fabric cleaning products. Our pillow cases are not washable and should be cleaned as above, we recommend using a pillow case for all pillows.
Q: How do I clean and protect the sheets/duvet/mattress protector?
All our accessories are machine washable, at a recommended 40 degrees. They can be tumble dried and ironed.
Q: My new mattress smells a little - is that normal?
Just like a new car, sometimes your mattress will arrive with something of the factory about it. This is totally normal and after a day or two it'll clear.
Q: Do you offer a guarantee?
Yes we do. Our 10 year mattress guarantee covers normal domestic home use. You can find out more in our Terms & Conditions page.
Q: Do I need to turn my mattress?
Please rotate your mattress monthly, there is no need to flip it.
Q: Do I need a mattress protector?
Yes you do need to use one to be eligible for the 100 Night Rest Test.
Q: How do I initiate a return?
If for whatever reason you would like to enquire about returning one of our products during our 100 Night Rest Test, please email us at: sales@hydeandsleep.com.

Once we've confirmed your request, we'll arrange for a free mattress collection between Monday - Friday within a 3-hour time slot.
