What independent reviewers found
Tom's Guide Dec 2025
Over a month at home, the writer used the TV preset so her partner could sit up while she slept, found that raising the head even slightly cut his snoring a lot, and used foot lift to ease knee pressure. The foot warming was the feature she valued most.
First-person month of use paired with a Sleep Number i8 smart bed, not a lab test; affiliate links on the page.
