The mattress will fully expand in up to 72 hours. Please note that this mattress is not recommended for use on a Bifold futon frame due to the absence of foam or any firm core. This leads to undefined edges, since cotton's inherent softness does not allow it to maintain a defined shape. Over time, the mattress is expected to flatten somewhat and increase in surface area, as its thickness expands lengthwise with use.
