Key Advantages
Why Choose Sleep Number ComfortNext
- Advanced relief for hips, shoulders, and knees
- 50% more cooling than ComfortMode series
- Active temperature control included
Why Choose Loom & Leaf Memory Foam
- Best-in-class motion isolation — a partner getting up is essentially undetectable
- 5-lb density memory foam is Tempur-Pedic-grade, well above the 3-lb foam typical of boxed beds
- Ships flat by white-glove delivery instead of compressed, which protects foam cell structure
