Sleep Number ComfortNext Review: Quality Sleep Tracking?

Sleep Number’s new ComfortNext Lux is the brand’s most advanced smart mattress yet, and a notable evolution from earlier models that focused primarily on adjustable firmness. Starting at $3,999 for a Queen, the 13-inch mattress uses a new Tri-Brid construction that layers micro coils, responsive foam, and Sleep Number’s signature adjustable air chambers to deliver more targeted pressure relief, motion isolation, and personalized support.
