How long for a sea 2 summit mattress to inflate?

[Campervanningwithkid]

Just that really! Managed to order one from a German company. It’s been out of the bag about 24 hours now. One side looks fully inflated, the other side, maybe only 50% and less than that in places - it’s really obviously uneven. Just wondering how long it took new ones to fully inflate before? Before I wonder if mine is faulty, I’m very unlikely to find another or get a replacement I feel.

I left mine a couple of days trying to get back into shape but had help it a bit by bloweing some air in it.

In my experience they never fully inflate and I’m not sure they are supposed to. Either blow or use a pump to top it up.

Use an electric pump to blow it up and then leave it for a night or so. The foam will have more room to expand.
