Almost 7 years on our Select Comfort mattress, and I won't buy any other kind of mattress in future. You can make your side any firmness you like, your wife can control her side independently. The air bladder seems very durable, the pump and controls ditto. The bed doesn't sag or leak over time, in my experience.

The new ones have the option of a memory foam layer over the air chamber. I hate memory foam but some like it.

They have a new option now, the dual-temp mattress pad that allows each person to control the temperature, e.g. if you like it cooler and your wife likes it warmer, it circulates cooled or heated air. I haven't tried that.
