What the Sleep Expert thinks...
"PostureTech CoreSupport springs adapt in real time, lifting hips and shoulders while a zoned foam layer cushions pressure points. The result is a balanced medium feel that hugs, supports, and isolates movement so you and your partner wake recharged, not disturbed. This technology makes the Advantage Classic perfect for couples, but also for anyone looking to improve their posture as they sleep."

Perfect for my arthritis . No sore shoulders etc in the morning just so comfy .. Only downside is its not to heavy to turn but could do with handles on the sides to help to lift it if you have arthritic fingers but its a comfy mattress
