This unique grey-bordered mattress has been designed with a micro-quilted cool touch large onion design top panel. The mattress has been carefully constructed with a Bonnell open coil spring unit to allow the weight of the sleeper to be distributed evenly across a wide surface, providing a much more comfortable and medium-soft feel. Allowing the sleeper to wake up each day feeling relaxed and revitalized. Consisting of 8 layers of comfort, this mattress has two layers of next-generation NASA-inspired high-quality visco-elastic memory foam. The foam will shape the contours of your body and will relieve pressure from the building, great for anatomical support. The fabric of the mattress has been designed to be breathable with hypoallergenic and anti-dust mite fillings for a cleaner healthier sleeping environment. This will keep your mattress odor-free. With our new in-house technology your mattress will come vacuum packed, rolled boxed, and delivered directly to your door, making it much more environmentally friendly. We recommend that you do not leave the mattress rolled and boxed for more than 7 days after receipt. Vacuum-packed mattresses do not have side supports, therefore prolonged sitting on the edge of the mattress is not recommended.
