I have an inflatable mattress (basically like sleep number, but some other brand whose name I can't recall right now) and it's been fantastic for the last 4 years without any noticable wear and tear or degradation. We also have a 3 inch foam topper on top that has held up well, though that Will probably need replacement at some point. That said, one of the biggest gamechangers I've noticed for sleep regardless of mattress type is actually the box spring. Box springs suck, the bed frames that use arched wooden slats for support instead of a box spring feel way more comfortable and supportive, even with the same mattress.
