Looking for a foam mattress that supports, comforts and cushions you after a long day? With specialist three zone support technology, the Just Relax mattress from one of the most popular mattress creators, Silentnight, is designed to offer you the most relaxing sleep surface possible.
A 3-zone miratex® support system is engineered to cushion specific areas of your body. Your shoulders, hips and back are targetted with intense support, keeping your spine nicely aligned for proper sleeping posture, encouraging the best sleeping position for a truly relaxing night's rest.
With a medium feel, the Just Relax mattress is the perfect surface for any type of sleeper, being soft enough to let side sleepers' hips 'dip', and for back sleeper's hips and shoulders to stay at the correct level for healthy sleep.
A layer of memory comfort foam provides impressive pressure relief, gifting you with a weightless feel as you snuggle up and let your worries drift away while your joints and pressure points are contoured. This foam is able to mould to your unique shape, offering personalised support every time you climb into bed.
A soft knit fabric cover provides the final touch to this innovative mattress, with hypoallergenic properties that keep the Just Relax fresh, preventing the buildup of allergens for the healthiest sleeping environment.
