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 your mattresses? How does it work?
Oh yes, we offer a trial period of 40 nights on all mattresses. We advise that you wait at least 30 nights before initiating an exchange on your mattress to allow you enough time to get used to it. If before 40 nights and after 30 nights you are still unsatisfied with the mattress for whatever reason – Hyde & Sleep will exchange a like for like mattress free of charge providing that a mattress protector was used and that the mattress is not marked or soiled. Choose from a choice of mattresses, if you do prefer a higher priced mattress, then the difference must be paid at reselection. We are unable to refund any difference in price if a lower price mattress is selected. 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.

When it arrives


Q: Do you dispose of my old mattress?
Yes. Please see details below.



Q: How do I prepare my Mattress / Bed Frame for recycling?
We will send you a bag for you to place your mattress in. On the day of collection, and after your call from our team, please make sure that your old mattress is securely wrapped in its bag and sealed with tape.

If your mattress is super king size, it will not be covered entirely by the bag. Please slit one side of the bag and seal the protruding edge securely with tape.

We will collect your old mattress while delivering your new one.

Bed Frame:
You will need to make sure that your Bed Frame is fully dismantled. All drawers will need to be emptied and unbolted. Our delivery team will tape the pieces of your frame together and take it away.
Q: What happens to my old bed or mattress?
Firstly, we disassemble your mattress. All the different materials are separated and compacted into large bales to help save space when we transport to recycling destinations.

Metal Springs:
We send metal springs to a metal plant to be melted down into light iron products.

The foam in your mattress will be used as energy from waste generation or, once cleaned; it is used as underlay for carpets.
Polyester padding: The padding is used by the fibre blending industry as fillings in cushions for pets.

Mattress covers:
For hygiene reasons, mattress covers are difficult to recycle. Therefore, they are turned into fuels as an alternative source to fossil fuels, creating green energy and heat.
Q: Will any of my mattress/bedframe become Landfill?
We're committed to the environment and make sure that no part of your old bed or mattress reaches a landfill. All recyclable materials are reused, and all other waste is turned into green-energy.



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: Why do you recommend I try the mattress for at least 30 nights before exchanging?
Every new mattress requires a ‘break in’ period. If you have been sleeping on your old mattress for a long time, the change to a new mattress (particularly memory foam) can feel quite different and may take some time to get used to.

If your old mattress had begun to break down, your body may have overcompensated to ensure you were supported when you slept. Therefore, it's incredibly important to give your body and the new mattress time to adjust to each other. The memory foam in your mattress will soften and stretch from your body weight and body heat over the first few weeks, softening the 'breaking in' period, just like a new pair of shoes.

You do have the whole of the 40 Comfort Exchange, and we will be here every step of the way to ensure you get the best nights' sleeps you'll ever have!
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: My mattress has a slight dip, is this normal?
Over time your mattress will respond to your body’s weight and your memory foam layer will settle. FIRA (The Furniture Industry Research Association) suggests that your mattress might settle to a 3.5cm in your first year. If you feel that the settlement is excessive then please visit our support centre @ www.dreams.co.uk/help
Q: Do I need a mattress protector?
Yes you do need to use one to be eligible for the 40 Comfort Exchange.
Q: How do I initiate an exchange?
If for whatever reason you would like to enquire about exchanging one of our products mattresses during our 40 Comfort Exchange, please visit our support centre @ www.dreams.co.uk/help
