How long before you can sleep on a memory foam mattress?

I would expect the mattress came with instructions for this and I am sure you can contact the manufacturer or point of purchase to ask this question.

You should do as the instructions say. I am guessing 48 hours will be enough.
Even though it seems settled, it is probably still working it out.

So, honest question, what would be the worst case scenario of sleeping on your stable foam mattress? It came in a tube. They weren’t worried about that permanently deforming it, and I would imagine it took more force to keep it that way then you would exert in any one area.

Wouldn’t your worst case be not getting the “full experience” that first night? You’re not going to damage foam by doing exactly what it was designed for.

Sleep on that bad boy as soon as you can stand the smell.

@Cruiser Good point. The mattress didn’t come with instructions. However, I just emailed the manufacturer and he answered immediately by saying that it’s ready to sleep on! Now, too bad I’m already settled in my guest room for the night. :-p

@funkdaddy Another valid point. Didn’t even think of that. And thankfully, it doesn’t smell at all!

@LeavesNoTrace I myself heard it is good to give it time to “air out” to allow any gasses from the manufacturing process out-gas new foam odors

@Cruiser Your link was interesting. I once bought a foam mattress and I returned it because it smelled so bad I thought it was poison. I’m not sure I am convinced it wasn’t even after reading your article, but it was still interesting.

We slept on ours the first night.

If we had waited for the smell to improve, we probably would have waited a year. We ended up putting a down-filled pillow-top on it (kind of like a thick comforter under our mattress pad) for many months, which both helped us adjust to sleeping on just foam and helped with the smell.

I have never heard of this, and slept on my memory foam the same night it was delivered, but it was not rolled up, the mattress was deliverd from the store I bought it from. I did, however, order a huge memory foam bean bag love seat and it took about 2 days to fully expand.

@JLeslie I work with these types of polymers and IMO these mattresses should come with a full disclosure MSDS sheet as the link I gave pointed out there are many different types of polyurethane foams and some I would not be around without a NIOSH approved respirator. Knowing how foreign manufacturers like to make things on the I would have to have full disclosure of the isoscyantes and flame retardansts used in production of the mattress.

@Cruiser It was made in China and it made me nervous. I returned it. I truly feel it was poison, I don’t know what the chemicals were.

When I worked in retail once in a while a group of clothing would come in that also smelled like poison. We figured it was for shipping purposes, maybe to prevent pests? Although, it didn’t smell like bug spray as much as it smelled chemically, to use a scientific term. It usually was from an Asian country, as in the continent of, but sometimes we received clothes from Asia that did not have that smell. I guess it was certain manufacturers or transporters.

Well I don’t blame you @JLeslie and part of the reason I avoided buying one is there are little to no testing done on these foam composites long term health effects. The sites I visited to find info were chock full of people with adverse health symptoms when they slept on these.

They are amazing to lay on and the same research I read says there are greener alternatives on the market now with less odor complaints.

@JLeslie Oh gosh, now your scaring me! When I took mine out of the package it didn’t smell like anything at all. I’m hoping that’s a good sign…

@LeavesNoTrace From what @Cruiser wrote it sounds like yours is ok. Maybe it is one of the greener ones.
