How long do I have to wait until I sleep on it? It's been twenty-four hours and the mattress has expanded to the full 10 inches.

You should be all set to sleep on the mattress after 24 hours. My son didn't even wait the full 24 and has not had an issue with it.

Just so you know these mattresses work great however to eliminate the hump issue you are supposed to let it sit and expand 24-72 hours before sleeping on it to allow all material to expand correctly

yes..remember tho.. allow a day or two for the mattress to air out and to "inflate" to it full size.. sleeps very good!

Within the first three hours it looks like a mattress but I waited twenty four hours before sleeping on it and at that time it was fully expanded.I have been quite pleased with the mattress so far.six months of use

I've had mine since 12-27-12.It expanded to 11.5"on the corner I took a quick measurement on(I just measured it now because I never did)The mattress has been so comfortable that I forgot to check,I guess.

Mine took a good six hour to expand to normal size. Memory foam is memory foam. Our memory foam mattress took many hours to become useable. The better the foam the longer it takes.

I really don't understand your question. The box that the mattress top arrives in is quite compact. You need to open it and let the topper air out in a flat space for 2 days...before you put it on your mattress. Once you do this, you will be sleeping on a cloud...getting up in the morning refreshed, no pain, and actually maybe not wanting to leave the comfort of your bed!!! I would never give ours up!!

It's in a small box, when you pull it out it expands. My son sleeps like a rock on it, it's a great mattress. Just make sure you let it air out for a few days after you pull it out of the box.

I Was Amazed How Fast This Mattress Expanded! It Was Not Delivered Until 6:30pm But Was Almost Fully Expanded Within One Hour. Was Able To Sleep On It The Same Night. I've Had It For More Than Four Months And Just Love It!

Memory foam needs to be opened and left to air for some time...I forget if its 12 or 24 hours...before you sleep on it. Really important!

Hi, Doug - I ordered the Full mattress - need to correct my review. I wouldn't recommend since the mattress in and of itself is 5" high. Contact the folks at Tuft and Needle for another option. They are quite helpful. https://www.tuftandneedle.com

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 took few minutes to expand but it took a good 48 hours for it to feel complete and firm. My husband has a bad back so he likes firm mattresses so this has been great for him. Personally for me, I had to put my mattress topper for it to be comfy for my preference.

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 only weigh 170 lbs so I don't know if my comments apply for 200 lbs. The mattress is surprisingly firm; it feels as if it should be adequate for 200 lbs. After I first get into bed it takes a minute or two for the mattress to conform and reach maximum comfort. Unfortunately, if I change position, it also takes a minute or two for the mattress to reform. This is my only complaint. As a result, I don't change position very often and have learned to sleep mostly on my back. Fortunately I now sleep better than I did with my previous mattress. My mattress is now 4 years old and has not developed any lumps or suffered any degradation. The mattress may not be perfect, but it is easy to live with.

At first, I received a mattress with a tag that said it was twin XL aka 39 in × 80 in (99 cm × 203 cm). It started out at 74" and over a week or two expanded to 75" long aka standard twin. I contacted Sleep master and they sent me a brand new mattress. This one started out 78" and expanded to 80" as it should be. It's a very nice mattress and a GREAT mattress at the price point. Buy with confidence you will get great customer service.

We were nervous as well. Make sure you open it where it is supposed to be as it will quickly open. Let sit for a day or two and it will be fully expanded. Very comfortable mattress . We are totally happy with it.
