At first, the mattress is amazing. In less than 18 months it has deteriorated so much, you sink right into the springs and sleep has been horrible. Aches and pains all night. Warranty process tells me this is completely normal and meant to happen for maximum comfort. A stick laid across a mattress with no one in it does not show the issue. Warranty personnel refusing to pass me on to management or respond to emails. This is the second mattress from here that has done this, however, in 2019 they replaced that one-which is the only reason we bought here again
