I bought an Ashley Sleep mattress 1 month ago. It was defective. It never got the lumps out after being delivered rolled up. They took it back. They replaced it. This one sinks, cuts off my circulation, and causes my nerves to shoot off in my back and hips. I don't know what model it is. It was 600 dollars. If they don't take it back I will raise hell. It is a piece of crap and I paid cash. I didn't save up 3 years for a mattress and bedroom furniture to be stuck with crap. I do NOT recommend this product at all. Unlike a true Tempurpedic mattress, it only has a couple inches of memory foam on the top.. not all the way through. If you want a terrible night's sleep and want to feel like your body is broken the next day.. then by all means.. take your chances.
