Six year old bed, 1 joke of a warranty claim...replaced

We were sold a memory foam bed six years ago. The sales man recommended capitol. We trusted this gentleman and have regretted it since. It started out ok....ended up with two valleys and one hill. What I mean by this is where I lay, where my wife lays had a hill in the middle. We had it warrantied, what a joke. They do not replace the bed, they apparently just take it for a week and have it sit there....the bed they provided was a very painful bed to sleep on, which we actually ended up sleeping in guest room. Also the warranty process cost us 100.00 because we had to have the mattress picked up. We just got rid of the bed and replaced it with a Serta....My advice, find the mattress that fits you best, do not get talked into something by a salesman. Capitol may be the best for you, but it definitely was not for my wife and I.
