I like the chair position, yet the lounge position is not as comfortable as I thought. One the thickness and described in the Q&A and the image, is deceiving. The lounge thickness is only about 3 to 4 inches with little to no cushion. I just got the opportunity to open the chair into the lounge function. There is a loose object inside of the bottom fold/unfold part of the chair.  It feels like a large piece of wood. It moves around when I unfold the chair into a lounge. The only way to get to the object is to cut through the fabric. When facing the chair the object is on the left, somewhere in the unfold. When folding the bottom part to seat position, the object falls toward the fold with a thump.  What could this object be? Is it something to be concerned about?
