Does the mattress stay firm day to day,or do you have to keep reinflateing it ?

Stays inflated for the most part. With the built in pump, it only takes a few seconds to bring it back to full pressure. You don't sink to the middle overnight.

The mattress isn't firm. It is on the softer. My mattress filled up pretty quickly, but didn't completely fill out the sheet for a day or so. When it was fully set, it was much thicker than expected.

It stays under the mattress. You can let out the every every time or leave it inflated. One fits perfectly across my full size mattress.

Try this ...are you certain that you filled it up completely. When I was filling the bed it looked like it was at maximum fill so I laid on it to try it out and it was real soft in the middle and it dipped so I inflated it more and it is firm and comfortable with no dip. Hope this helps.

Yes, ours does that too. My boys are pretty rough with it though. It stays deflated while they are playing with it, so for us it's not too big of a deal to have to re-inflate each time we need to use it which is about every other day.

I don't keep it plugged in you lose some air but not a lot, I've used it about a week straight and only plug it in to replenish the air every couple days. I think it also depends on how firm you like it. It get's really firm.

This is pretty firm. If I have to sleep on it more than one night in a row, or for guests, I use a memory foam mattress topper to soften it up a bit.

I have to say I've used my bed several times over tthe past few months and never had an issue with it deflating! Actually had friends over and they used it 3 nites in a row and only repumped it once. And it wasn't completely deflated.

I think it is rather firm. I also noticed that after sitting on it, it would spring back up like a tempurpedic mattress

We just use it for trips and guests. It is firm. I slept on it several times and did not have any problems the next day with my back. I don't use it every night either, though.

Quit the opposite. The mattress is suppose to start off fairly firm and after awhile of expanding it gets softer. Especially with warmer temperatures.

It takes time to expand but it does get firmer after a few hours. I made the mistake of resting while it was expanding and I woke up with some back pain, not sure if it was because it was still expanding but I recommend letting it finish first. I've had it for about 5 months now and its still firm yet comfortable.

It certainly softens a firm mattress. Some comments on here said it's like sleeping on a cloud but I don't really agree with that. It may feel like that initially but it settlers down a bit after awhile. Still feels wonderful & I can't imagine sleeping without it on the bed! I will always have it on the bed.

It is firm but if you apply pressure it mashes down. It does pop right back up once pressure is released. You don't need to push down on it to use it.

The longest I have had it inflated and used it daily was about ten days. I slept on it those ten days and was very comfortable. It was the first time it had been used, and as the instructions state, you need to check it every day or so to see if it needs a little more air. It did on a few of the days, but not a lot of air at all.

I have a twin size and had no problem with it staying inflated with one person sleeping on it. In fact, it stayed inflated for four nights without re-inflating at all.

My wife and I have had our mattresses for over a year and are well satisfied. I have to sleep with my head elevated and the constant up and down action hasn't caused any deformation. I find mine to be very comfortable, but my wife would like to have hers a bit harder.
