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.
