how long does it take for the mattress to fully expand?

Maybe two hours at the most. I think the instructions said to give it a day to completely expand, but I did not notice any difference between the two hour mark and the 24 hour mark.

You have to inflate this mattress by blowing air into it. The instructions say it takes about 20 strong breaths to inflate the mattress.

I've not blown up a twin mattress with the pump, but I'd guess it would take 5 min.

The mattress expands to about 5" in thickness. That's still shy of standard mattress (which is usually 6"). If height is an issue (as in it needs to be a bit higher), I recommend purchasing a foam mattress pad to go underneath it to bolster it just a bit.

It takes about 3-5 minutes for each twin mattress if you're putting two together to make a king. I'd imagine it would take somewhere around 5-7 minutes if it's one continuous king size mattress. Really depends on if it's a double stack, if it's one continuous mattress, and how fast you pump!

It is amazing how compact the mattress is when shipped. I am not sure the actual package size will be of the queen size, but the package I got of a twin XL size was about 15"x15"x 18". It took about six hours to fully expand to its full size. There was no odor problem detected, and none since I have had it, going on six months.

After the recommended time for it to get to full thickness, it fits just barely inside of the edge of our mattress on the sides, otherwise plenty long. If you're measuring it in its compressed form, you won't get an accurate measurement.

I put it under the mattress cover AFTER it fully expanded. It took mine a full day to expand.

Ours was fully expanded within 4 hours. Ends never curled up. Totally satisfied with our mattress.

It arrived by truck shipment compressed to about 2" thick and rolled up in a poly wrapped cylinder about 12 inches in diameter x about 7 feet long. We left it unopened for a couple of days until we could move out the old mattress and box springs and install the new plywood support boxes. When we placed the new foam mattress on the support and unrolled it and removed the poly jacket (it is vacuum sealed) it expanded to full thickness in a very short time. Only the manufacturer could tell you with authority how long it can remain unopened after delivery, but keep in mind the mattress is imported, and spent an indeterminate period sealed up and in a warehouse or in shipment. I personally would not hesitate to leave it unopened and still rolled up for a few weeks.

It take 5-10 mins to have everything ready. The base is set in 1 min, u have put the cover of it and thats it. then, the mattress.... you just put it on top of the base, (it comes totally compacted...) so u take the plastic off as per the instructions and u ll see how it gets expanded in minutes. I love this mattress it is really nice

No time at all. I just left it overnight so it could air out. But it took shape shortly after I opened the package. Great mattress

It takes about 1 minute to fully inflate with the pump that comes with the bed. Just used it for the first time two days ago - it is great!

It expands once it is unpacked, within 1-2 days Do not send it back until u have allowed it to expand

Hello! I'd guess it would take six or seven minutes. My wife and I have single-size air mattresses and it usually takes about 100 up/down cycles. That translates to about three or four minutes. I like the pump because I don't have to rely on a battery or an electrical connection, but I'll also probably end up getting a better operated pump at some point just because of the convenience and, in the warm months, the ability to set up with less chance of building up a sweat. Good luck! Tom
