Dormeo Octaspring 6500 foam mattress! Used for 2 years, has been in storage, hoped I would be able to cut down from king size. The memory foam springs are a special design that I found out cannot be cut down to resize. This is a medium firm foam mattress rated A for motion isolation, pressure relief, has better breathability than traditional memory foam, ideal ventilation keeps you cool and provides support for your entire body: it helped my hip & neck pain when sleeping. I purchased a Sleep Country mattress protector that was on the mattress from our first sleep. It has a waterproof membrane & dust mite barrier. We are now living on a boat, I need to replace this wonderful king size mattress with a queen size. I want this great bed not to go to waste sitting storage. This bed new from Sleep Country (new model number)is $3900.
