It says it takes 48 hrs to be up to full size but it will be 90% after a few hours. I was hoping you don't have to wait 48 hrs to use it.

Because of the gasy smell you should wait overnight before using it. It comes to its full size a couple of hours after opening the package. Very comfortable. Good sleeping to you!

You don't have to wait that long for the reason of size. The chemical smell kept me from using it for several days.

No you do not have to wait 48 hours to use it. I used it the same night I got it in. I let it expand for a few hours, and it worked great. Hope this solves your problem.----Barbara

I used it withiin aobut 6-8 hours after opening it and it worked just fine. I saw virtually no difference between the first night I used it and the second. I really am glad that I purchased this item!

You don't need to wait 48 hrs to use it. I used it the night I received it.

I thought this was a strange comment also. I started to use mine immediately and I could not tell it expanded at all.

I used mine just a few hours after I received it. It didn't take long for mine to expand at all.

I do not have it at the location I am working from this week but I am pretty sure mine turns to a couple of milimeters no more than 5 milimerters from 60. I've never actually checked to see if the time is 60 minutes or not. We use it to stay on track in 45 minute sessions.

No - you dont have to wait at all, its just a guideline for it to be full size

48 hours is the recommended time. I wouldn't recommend this product, though.

I usually don't wait more than a few seconds. The color doesn't seem to change the longer I wait and the color pad will change colors as the area dries. Hope this helps.

It might take 20 minutes. If you're looking for fast, this is not going to be fast. If you want to use it at home it works great.

It takes a couple of hours, I think, if the battery is empty. I've since bought a second battery for mine so I could do double the work withoutwaiting if I feel like it. Charge them both at night for next time. Still love it!

This was originally offered to me as a trial; when it arrived it was a full size product. At first I didn't think it lived up to its claims, but it just took a little longer than it says to show results, so I decided to continue using it rather than try something else and start over.

No, it does not take a whole day, a pretty short time actually. I have never timed it exactly but what Richard Pham said sounds right.

That is the suggested time to wait. I waited an hour, lol. As soon as you remove it from the packaging it starts to expand. It's actually really fun to watch. There is a smell that it has at first that eventually fades within a few days.

Quite while. I fill it and then walk away, so it takes 2 or 3 hours at least. If I go back to the kitchen I often top it up, it seems to work faster if it is full or near full and using the entire filter.

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.

It depends on how much battery life is left. For me, it usually took about 1 to 2 hours to recharge full. I hope this helps.

I have been setting my timer to 9 hours, and that seems to work well. You can control the timing. If you think 9 hours is too long, set for less.

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

More info: I used it again, but this time I timed it. I guess "time passes quickly when you're having fun," because it actually took a full 10 minutes! Not your 15 but maybe yours is OK. You may have a different make. No idea why I gave the prior answers of 2 -3 minutes and 5. Sorry.

Yes, 3-4 hours is no problem, but all day is probably going to be too long. It seems to be more effective to wear it off and on so to speak rather than full time.
