Water-cooled beds
were never really solved.
They leak.
Tubes, joints, connectors — every pressurized water system has failure points. Users report leaks destroying $3,000+ mattresses after 12–24 months.
Not if. When.
They're loud.
Water pumps run at 55–70 dB. That's louder than a normal conversation — at 3AM, while you're trying to sleep.
55–70 dB at 3AM
They charge forever.
$17–33/month subscriptions. Stop paying and features lock. Over 8 years you spend $4,000+ on top of the purchase price.
