Top complaints
SoundAsleep Dream Series Air Mattress
- Some owners say it slowly loses air
Good Housekeeping lists 'deflates a bit over time, according to some online reviewers' as its con. Amazon's summary is mixed on air retention, with some saying it keeps losing air, and several mention a slight leak. A Wirecutter staffer's twin sprang a leak on its first use.
- Strong PVC smell
Wirecutter found it had the strongest off-gassing smell of all the mattresses it tested, and the eye-watering odor barely faded over 21 days.
Source: Wirecutter - Slow to pack, fiddly cord storage
It took Wirecutter nearly five minutes to break down versus about three for its picks. CNN notes the cord goes in an open hole rather than a latched compartment and there are no folding instructions.
