Combining premium materials and an expertise born out of decades of experience in creating top-quality mattresses, Relyon�s Pocket Memory Classic 1500 Mattress blends both performance and good looks to bring you a next-level orthopaedic mattress. It uses 1500 individually pocketed springs in the King-Size model with a layer of space-age Memory Foam to cushion and cradle the body, giving you maximum support with no compromise on comfort.This is a single-sided mattress, which means there�s no need to flip and turn it to prolong its life. However, we do recommend that to maximise the lifespan of your Pocket Memory Classic 1500 Mattress, you should rotate it head-to-toe every few months. To make this easier, the mattress has robust turning handles attached to the sides. This mattress is an NBF-approved product. It�s made in the UK, and comes with a manufacturer�s 8-year warranty for your peace of mind.Whereas most mattresses tend to suffer from �side-sag� because the stitching and reinforcement doesn�t go all the way to the edges, the Pocket Memory Classic 1500 Mattress from Relyon avoids this issue thanks to the strengthened edges. So even if you prefer to sleep on the edge of your mattress, or you like to �starfish� and spread right out, you�ll get the same level of comfort and support right across the entire width of the mattress.The Relyon Pocket Memory Classic 1500 Mattress is rated as firm, so you can be sure you�re getting the maximum amount of support to take the pressure off your spine, shoulders, and hips. But that shouldn�t mean compromising on comfort, so the inclusion of 1500 individually pocketed springs in the King-Size version, along with a dense layer of Memory Foam gives you a softer feel while at the same time cradling and supporting your body, whether you sleep on your back, your sides, or your front.The knitted cover gives this premium quality mattress an elegant and snuggly-soft feel, while the use of hand-tufting ensures that the plush layers of filling stay exactly where they�re supposed to be! That means less chance of lumps and bumps later on in the mattress� life, and a mattress that looks as good as it feels.
