This FTW. Like I'm really surprised why ppl cheap out on beds when you spend a decent amount of your life on one. I got the P5 King, which hey now being divorced, man I never felt more at peace fitting in a king size bed.

Sleep number. I bought my p5 about a decade ago, and I will never have another mattress. And since these are modular, I could, technically, kind of actually never have another mattress. I have the split king and dual adjustable bases,, and all told it was about 4500. I got the bases at costco for less than half the price, but the mattresses themselves are sleep number. Would I have a split king if I bought another? No, that was bc I was married at the time. I sleep crosswise if I want to. The most annoying part is the sheets for that. But still, I took it with me in the divorce and it's fine. My ex bought another one immediately :D They did not get the split king, although they, ah... could have? I guess :D (Pro tip: be sure to get your OWN sleep number app and profile if you don't want other people knowing how both you and whatever is going on on the other side of the bed sleep :D) Honestly, I have the p5, which is very basic, but I didn't want memory foam, and I don't care if I have the other bells and whistles. (ANd again, it's modular, so you really could hack it and upgrade if you were inclined)

I've had mine and my adjustable (costco) base for a decade, and will never have another type of mattress. I have a p5.

I've had my p5 sleep number for a decade and it is the last mattress I will ever buy. I love it. I also have the adjustable base (but from costco, so about 1/3rd the price). Mine's a split king with a split king base, and if I had been single when I bought it, I'd just do a regular king, but still go with the P5. But the split king is fine, too. Sleep number is also modular, so if parts wear out... you just replace. (Actually, some people gradually "upgrade" into other models, Johnny Cash One-Piece-at-a-Time style, as well...there are whole YouTUbe series devoted to this :D )

We have a Sleep Number p6 and love it. Got the split king base with the light and the foot warmer. Bought it in 2019 to level up from our p5 we bought in 2012.

We're on our second SleepNumber mattress. First one lasted 12+ years until we decided to upgrade. When the time came, there was no question about buying another SleepNumber. We're 100% happy with SleepNumber beds. The newer one cost approx $4k

Same. We purchased one last year and it's been a game changer. People scoff at their price, and yes they are expensive. $6K+ for a bed seems crazy until you experience good rest. We have a split top and it can auto raise if one of us starts to snore or whatever, and it really does work. I sleep better on a firm bed and my wife sleeps better on a soft bed. We each have our side adjusted how we like it. We went through 3 of the other name brand foam beds over the last 5 years trying to find one we liked. We could just never get comfortable.

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.
