Sleep number king size with adjustable base. About $7,500. Absolutely best frivolous purchase we've made. Love it.

I’m not a Sleep Number shill, I promise. I bought one eighteen months ago with an adjustable frame and I’ve never slept better. I wake in the same position that I fell asleep in with no pressure point aches or pain and head up so no more GERD wake ups. They are not cheap, but I got what I paid for.

Using a firmness adjustable cooling mattress from Sleep Number. Keep it dialed up pretty dang firm because if I sink down there’s gonna be serious back pain waiting to greet me in the morning. Wife says it’s like a board, lol.

I had a king size sleep number for about two days. No one tells you the king size has a huge, uncomfortable bar down the middle and no matter what you do, the air mattress pushes you towards that bar. You can’t fix air mattress physics. Also, it’s not everything but sex on two twin air mattresses glued together sucks.

I am a side sleeper as well and I sleep with a CPAP mask on. The most comfortable mattress I’ve used is a Stearns & Foster pillow top. Very comfortable and support. Also consider an adjustable base. The sleep number mattresses and base are amazing also because you can adjust the settings. My life goal is to get one.

I like my Nectar mattress that I got on Amazon for less than $700. I prefer it x100 to the SleepNumber that I spent thousands on.
