So very disappointed. The mattress cover has detached from the mattress in spots. Mattress is lumpy. I wake up in the night several times hurting in my back and shoulder because the mattress is too hard. It is VERY uncomfortable to sleep on. Even though the manufacturer said they had a 90-day money back guarantee, they can't find my notification about the faulty mattress and the 90 days has passed. Not worth the money spent especially for someone like me, retired with a limited income. DON'T BUY THIS MATTRESS!
