3. SoundAsleep air mattresses are made to be durable, resistant to holes and maintain the proper firmness over the course of the night. When used for more than 2 nights in a row, it is recommended that the user “top up” the mattress with 10 seconds of air. This is to ensure that any microholes that formed in or around the pump or valve will not impact the firmness of the bed and your night’s sleep.
I got my Soundasleep air mattress last week. Given my living situation in the past year I have been using air beds quite a bit and have had (unfortunately) more than a few models. So far I have been pretty impressed with this one.
