Causes strain and pain on the lower back to sit on it.

Looks nice. Seems to be well made and the Sunbrella fabric is nice. Our concern is that it is very firm and the seating is very shallow. Hard to get comfortable on it.
For a 5’4” person, the seating does not support the length of the thigh to the back of the knee. It is short by about 3-4 inches when sitting on it with back against the back cushions. The sitting position is uncomfortable.
We chose this sofa based on the fact that it was “standard” seating depth, but in fact it is quite shallow. Not sure if this has to do with the size of the back cushions (). They are very imposing.
Causing strain on the lower back to sit on it.
Now Wayfair says we have to package it up and pay for shipping to return it in order to purchase an alternate option.
Very dissa
