This full-foam 13-cm-deep mattress has been designed with an open-cell next-generation Reflex Foam, which does not contain any springs, providing medium-firm comfort. The reflex foam is made up of thousands of air bubbles that expand and contract when the sleeper lays on the mattress for firm support. The low-density reflex foam provides both body molding and bounce-back properties, which offer the sleeper a firm yet hugely comfortable sleeping experience while always returning to its natural shape when it is not in use. With a cool, soft, stress-free breathable fabric for both the top panel and the border, this maintains any excess heat, keeping the sleeper at room temperature for a cool, fresh, relaxing night’s sleep. The mattress will be delivered, compressed, vacuum packed, rolled, and boxed for comfortable and easy delivery, making the unpacking of the mattress simple for the customer. Once the mattress has been taken out of its packaging, please allow 24 to 48 hours to allow it to expand to its original size.

Firm, Kingsize (5'), Cream

An all-foam mattress designed using high-quality materials for an uninterrupted night's sleep. The mattress features high-density reflex foam as its core material. Reflex foam is a no-sink material as a very supportive and durable foam. Unlike memory foam, reflex foam is fairly firm, is not temperature sensitive, and does not mold to your body, it provides a relatively quick bounce back. Due to these special properties, the foam provides great support, it will distribute your weight evenly to relieve pressure from key areas such as your neck, shoulders, hips, and back. Due to the springless design, the mattress allows for a silent, undisturbed night's sleep. 'No roll together is a great advantage to an all-foam reflex mattress. This means both users will not find themselves rolling towards the middle of the mattress, you will also not disturb a sleeping partner when moving around at night. The mattress comes complete with a quilted cover for extra comfort. The cover is also removable to allow for easy cleaning and maintenance. Sanitized materials are used to provide hypoallergenic and anti-dust mite properties. A great mattress for allergy and asthma sufferers. This mattress is vacuum-packed and rolled for easy delivery. Please allow up to 72 hours once opened for the mattress to expand and reform to its original shape. Please Note: The additives used in the manufacturing of foam may give rise to a slight odor. If this should occur, please remove all packaging and store it in a well-ventilated room for 48 hours. The odor is safe and will dissipate over time.
