How would I make the back of this chair? I'm having a difficult time trying to figure out how to create the back and bottom part of this chair (not the legs, just the outline of the chair). I thought about doing some extruding from creating the bottom but then I got very confused on how to create the circular backing and its seams. I'm still learning each day and this chair might be too advanced for where I am I guess but any pointers would be appreciated!
You can begin with a 60 vertex cylinder, make an inset:

Extrude a quarter of the border faces:

Move up some vertices to make the bumps:

Push a bit back the whole top:

Create some edge loops to round the shape and to prepare the seams:

Select all and make a Mesh &gt; Symmetrize:

Some additional edge loops:
