Can you face a problem with a Memory foam mattress not fully expanded? Temperature plays a major factor as well, if it’s extremely hot out or very cold you can expect your memory foam to take much longer to expand since heat speeds up the process!


Weight is also an important consideration.

If you are purchasing a twin-sized mattress for yourself and have no problem carrying it upstairs this will not be too big of an issue but should someone with frailer bones need assistance moving their new purchase they might find that there is some residual compression which could slow down expansion time.


The larger your memory foam mattress the longer it takes for expansion due to higher amounts of air having been trapped inside when compressed down into a box or bag!


Thickness also plays an important role in how quickly memory foam responds after being opened up from its compressed state! 

The thicker the mattress, generally speaking, means it will take slightly longer to reach full size and thickness so you can expect anywhere around five or six hours of waiting time whereas thinner models may only need two or three depending on their individual characteristics.


Density is another factor, with higher densities taking longer to expand. This is due to the material having less space available for expansion as there are more molecules packed into a smaller area.

How To Expand Gel Memory Foam Mattress?

The best way how to make memory foam expand faster is by leaving it in a room with some heat and humidity.

However, if you’re impatient like us we know that just laying on the bed for an hour or two will help as well! Below Is the Explanation of how to expand memory foam:

Open Your Memory Foam Mattress In A Right Way

When you unpack your memory foam mattress, you will need to cut the plastic packaging and remove the rolled-up foam from the inside of it.

Then you can lay it out on a flat surface away from direct sunlight and heat (heat speeds up expansion time which is why we recommend waiting) and allow it some time to reach its full size before using it.

Don’t worry if you don’t give it enough time while unpacking, unlike traditional innerspring mattresses that cannot be removed from their plastic wrapping without causing damage; open-cell memory foam won’t suffer any such ill effects by trying to hasten this process!

We recommend waiting at least 24 hours before sleeping on your memory foam mattress, though larger models might require upwards of 48 hours.

This allows the air pockets inside of the material time to fully expand which will allow for maximum comfort, support, and durability!  Add A Protective Bed Sheet Over Your New Gel Memory Foam Mattress And Enjoy the Luxurious Feeling Of Latex.
