It's 8" tall and made with cooling gel foams and adjustable air chambers. This means you can customize the precise firmness level of your side of the bed to suit your sleep position and body type. Plus there's integrated sleep tracking sensors. There's usually $200 off when mattress sales hit at Sleep Number. So, the current deal knocks an extra $100 off a queen, and including a free Essential Sheet Set worth $159.99, is worth taking advantage of.

The c4 smart bed is a step up from the c2 smart bed. It's slightly thicker at 9", offering a more cushioning feel and better pressure relief for side sleepers. The current deal isn't quite as good as last week's 20% off the c4, but $1,519 for a queen-size smart mattress with this build, in-bed sleep tracking, and customizable comfort is pretty hard to beat. For reference, you can expect to pay $4,199 for a queen Saatva Solaire, a more luxurious take on an adjustable firmness bed.

At the other end of the Sleep Number spectrum is the Climate360 smart bed, ana active heating and warming, sleep tracking, customizable mattress. Honestly, it's the complete smart bed package. Of course, this means it comes with a high price. MSRP starts at $9,999 for a queen-size size but it's down to $7,999.20 after 20% off now. That's equivalent to the lowest price we've seen it sell for, and it includes premium delivery worth $250.
