Good idea, we HATED our Sleepnumber and had paid a lot for it. Now we have a latex mattress where you can buy layers of varying firmnesses and switch them around to get the best comfort for you. They allow a trial period also and you can switch out layers if need to. Also can buy split mattress which we did if your partner likes different softness. There are a couple companies that do this. Savvy Rest is a good one but expensive. There are less expensive companies that do this also. Also like that it comes with an organic cover and latex is organic if you buy the Dunlop latex but the Talalay is slightly softer but still natural, no odors, actually smells very very faintly of vanilla. Love ours. Just don't get if allergic to latex. We had first purchased a memory foam to replace our uncomfortable Sleepnumber and sent it back bc it smelled so bad and was putting pressure on the back of my legs.
