Key Advantages
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
Why Choose Black Diamond
- Ice Flex Cooling Technology provides outstanding temperature regulation
- Premium hybrid construction with individually wrapped coils for targeted support
- Multiple comfort options (Plush, Medium, Firm) to match your preference
