Sleep Number ComfortMode review

Sleep Number ComfortMode ranks ninth, a specialist pick rather than a default. Its point is adjustable firmness on each side of the bed, so two people with different preferences can share a queen without compromise, and either can change the setting later. The 10-inch ComfortMode adds joint and pressure point relief and built-in cooling materials; the 11-inch ComfortMode Lux targets hip relief and costs more. The queen started at $1,799.10 on Sleep Number's US store when we checked, against a $1,999 regular price, and direct orders include a 100-night trial and a 10-year limited warranty, with full coverage for the first 2 years. Costco lists Sleep Number among its mattress brands. It scores lowest on ease of use because an adjustable air bed has more parts to set up and look after than a standard mattress, and its value score reflects a high price for a 10-inch bed.

Who it is for

Couples who disagree on firmness and will pay a premium to set each side separately.
