Had one about 10 yrs ago - loved it for the first two years then the foam in the middle that separated the two mattresses gave out and it was like sleeping in a big hole. Replaced the foam in the middle and I could never get close to the wife, it made both of us roll away from each other. Tried cutting a little of the foam away to lessen the height and we were back in a hole. Ended up trying to stuff towels down the middle to even things out and they just balled up causing lumps. Gave it to my son in law cuz I was pissed at him, then he got pissed at me for pawning if off on him and he had to take it to the dump. Would I buy another - HELL NO! Biggest waste of $4500 I ever spent.
