Jim, that description of your bed in the first post was turnin' me on

Well, you could have left the "Wife" part out. JK
We have a King size Sealy foam mattress, but not sure if it's the same as Jim's. We've had it for 4 years now and don't like it. We can't flip the mattress over, we can only rotate it. The best bed we have is actually in our first guest room and it's a Queen Sealy with springs, but has a nice foamy top. It gives us the support we need, but it doesn't cause any redness. We're working on cashing in on our Sealy warranty again, which is pretty good if you bought a good mattress to begin with. All our mattresses have a 10 year warranty and if there are any indentations an inch or more that will not pop back up, they'll replace it. We're hoping to get a King size mattress that is the same model as our old Queen. Hubby is 6'2" and when he flips over, he takes up half the bed and then some even with a king.
Not all mattresses work for all people, so it would be great if you could get a store to allow you to use one for about 90 days or at least 30, before you actually accept it as a done deal.
As far as wetness goes, my hubby never cathes, he uses a urinal. But sometimes there is a little spillage and for a while I used the disposable pads you can buy at drug stores or Walmart, Target, etc., but they are thin and the plastic tends to make hubby sweat, even with it under the sheet and mattress pad. I get catalogs from a company called Dr. Leonard's and they sell all types of equipment and such to help people with disabilities and they have these mattress pads that are quilted and the bottom is strong plastic so nothing leaks through and there is more padding in between hubby and the plastic so he doesn't sweat. I bought a couple of them. They are washable and have held up for a couple of years now. This catalog actually has very inexpensive stuff I've bought throughout the years. Much cheaper than going through a Med Supply store. Here's a link to Dr. Leonards catalog online. They sell all kinds of things for the home that's good for AB people as well.
