Features of This Orthopaedic Mattress If you're looking for a high quality orthopaedic memory foam mattress, you've come to the right place. The Zen Ergopedic Pocket Memory Mattress is the go-to orthopedic mattress for side sleepers, couples with varied sleeping positions & those who prefer the traditional support of pocket springs. Triple-Layer Design So, how does this pocket sprung memory foam mattress work? Soft memory foam forms the top layer of this three-tier mattress design, providing luxurious comfort & pressure relief. The second layer is made from a higher grade & more supportive memory foam to support your joints & lower back. The third layer is made up of individually nestled pocket springs, which provide personalised support. A memory foam spring mattress is a particularly good idea for partners with notable weight or size differences, as the pocket springs provide independent support for each sleeper. Why Choose This Product? This orthopaedic mattress comes with a luxury quilted mattress cover. This mattress cover is removable & washable at 40 degree. Equivalent to 1500 pocket springs in a king size mattress.
