Frequently asked questions

How easy is it to set up Sleep800?

Sleep800 is simple to set up.

 

Follow our easy to read assembly instructions and your mattress will be set up in minutes.  

What bed foundations do you recommend for Sleep800?

Sleep800 has been designed for use on all foundation types. As a general rule for foam beds, the more supportive the base, the more comfortable you will feel. For the ultimate system and support, we recommend Design.Online's Flex Bed.

Can my Sleep800 Mattress Cover be washed?

Sleep800 Mattress covers are completely removable and the unique shape of the mattress allows for the cover to be easily unzipped. The mattress top cover can be unzipped and removed separately and is machine washable in warm water.

 

Individual covers are available for purchase and are the perfect solution when machine washing is not enough.

How do I adjust the firmness of my Sleep800 Mattress?

Adjust the firmness to suit your sleep style. Just unzip the washable cover and flip the foam layers underneath for your preference of medium firm or firm comfort.

Lay the white side on top for a medium firm comfort level, or the grey side on top for firm comfort.

Does Sleep800 have edge support?

Sleep800 features built-in edge support that, unlike sprung edges, doesn’t affect the edge feel of the sleeping surface. The same system is used in the foot and head of the bed, meaning that if you rotate your Sleep800 you will still have all round edge support.

Can I sleep on my Sleep800 Mattress straight away?

Pre-Delivery, Sleep800 is compressed and packed into a cardboard carton. The compacting of the mattress will not affect the mattresses performance and is done to provide effective shipping and delivery, saving precious carbon miles whilst providing you with the best possible convenience and value for money.

 

You can sleep on Sleep800 straight away, but it will take up to 24hours for air to fully circulate through the mattress, which will reform its shape.

Does Sleep800 have any certifications? 

Designed with sustainability in mind, all foam used in Design.Online furniture is CertiPUR-US® certified, meaning it is made without ozone depleters, mercury, lead and other heavy metals, formaldehyde, PBDEs, TDCPP or TCEP flame retardants and has low Volatile Organic Compound emissions for indoor air quality.

How do I recycle packaging?

Design.Online packaging has been designed with sustainability in mind. Cartons are made from recycled cardboard and use water based inks. Cartons can be disposed of in your kerbside recycling bin.

 

Inner packaging is printed with soy-based ink and our tissue is completely acid free and FSC Certified.
