It sounds like because you have had the mattress on it’s side, some of the foam layers inside have moved around. These layers are independent because of our modular design.
If you zip open the bamboo cover, you will be able to re-align the layers of foam inside to make sure that they are sitting nice and straight again.
Should be an easy fix, but if you run into any problems please feel free to give us a call.
