When we had our TT, I also purchased and installed one of those sleep number Chinese knock off brands and it lasted several years. When we bought the mh, I transferred the bed to the Mh and used it in there for a couple more years. Then one morning I awoke with a huge bulge in the air mattress running length wise between us. Sure enough, the separation chamber had become disconnected inside the mattress.
We have had an Sleep Number mattress at home for about 10 years or more (old remotes with cords) and it has worked flawlessly. So, went to CW and paid an outrageous price for the cheapest queen size sleep number I could get. It only has one cordless remote that we have to share, but we typically stay at one set number (different one for each of us) and very seldom ever change it. So, it works for us and I expect it to last as long as we have the mh.
