I can't find seat cushions for this set. The chair seat is 17" wide and 15" deep with a curved back. See attached photo.

Also, there were a couple of problems with the assembly. One of the bolts on one of the chair backs had to be struck with a hammer to align it with the slots of the chair seat and I had to retap one of the threaded holes in the table. All four of those holes created some difficultly in threading in the bolt into it.

Can you assist me with the cushions. Thank you.
