Owners praise the cooling, but leaks are the dominant complaint, often after one to three years, and a few woke up to a soaked mattress.

Fully light-blocking, including for side sleepers and with CPAP; stiff cups need a break-in period.

Cooling and comfort that last for years; some report leaks, early failures and app scheduling woes.
