In practice, it takes a while until you have first been pale the sofa. Depending on the stamina you need already own about 20 to 30 minutes to both air bags (seat, backrest) aufzublaßen. The seat takes thereby substantially longer than the rest. Who goes briefly to the outdoor pool or generally schedules no long use of the sofa, is probably more blow than to sit on the sofa.
If the sofa then be pale done once, even kanns go directly already. Two normal people find it plenty of space. Since the bed is designed for two people, it is quite stable and is more likely to hardly burst under normal use and amount of air inside.
At a price of about 13 euros you can here really do anything wrong.
The only negative thing about me: The air is pretty fast out of the bed. If you sit An hour later, you realize clearly when standing at the latest that it has declined to air and must first blow again for a few minutes.
Otherwise 4 stars and strong buy recommendation from me ...
