This ia a Invacare Solace 1080 twin size mattress.It measures 80"Lx36"Wx6"H. This mattress is the kind used in hospitals for someone who is bed ridden and helps prevent bed sores. I realize some might not want a used mattress but this is very clean. From the time we brought it home it was covered by a plastic cover the a quilted mattress cover, the fitted sheet and a waterproof pad. It is very sanitary. Pick up in Abbotsford B.C. Cash only please
