What are Just Sleep mattresses?

Silentnight’s Just Sleep mattresses are premium, innovative mattresses that are designed to perfectly roll up into a box, without compromising any of their incredible features. Available in sizes ranging from single to king size, there really is a Just Sleep mattress for everyone. Innovative, practical, and highly supportive, each Silentnight roll up mattress is a credit to this famous manufacturer's sleep expertise.

What Just Sleep mattresses are available?

Within the Just Sleep range, there are plenty of features and designs to choose from based on your needs. All of the hybrid models in this range feature Silentnight’s bespoke Mirapocket® spring system - pressure-relieving, individually pocketed springs that target your body’s pressure points with expert precision. The Just Dream Mattress, for example, utilises these clever springs alongside a generous layer of ReVo™ Foam, which moulds to your body while cooling your temperature.

If you’d prefer a no-springs Just Sleep mattress, take a look at the Just Relax 3 Zone Foam Mattress. This Silentnight memory foam mattress provides three essential areas of maximum support, keeping your spine nicely aligned for a healthier sleeping posture. The thick memory foam layers contour to your unique shape, offering you personalised comfort so you can, well, just relax!

There are plenty of other Just Sleep mattresses available at MattressNextDay, such as the Just Breathe Eco Comfort Mattress, featuring sustainable, highly breathable Eco Comfort Fibres™. Or, consider the Just Bliss Gel Hybrid Mattress, with its layer of Silentnight’s innovative Geltex® cooling gel to cool you down to the perfect sleeping temperature. If you're looking for a mattress in a box that offers incredible support and comfort, you'll find your perfect match in the Just Sleep range.
