Key Advantages
Why Choose Sleep Number i8 Smart Bed
- Adjustable firmness 0-100
- Dual-zone for couples
- Advanced sleep tracking
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
