We bought these rockers for an older couple who are larger people in general.  It fit them just great!
My father-in-law loves my spring chairs but I couldn't find a set within our budget.  These chairs are a great compromise!  Smooth rocking and sturdy to set in.  Also they didn't have any trouble getting up out of them!  They need a cushion and I had a hard time finding one to go with them.  The dimensions of the seat aren't well published.  All in all, we loved these and were proud to give to my in-laws for their 50th wedding anniversary!

Pros: Great value, easy assembly, sturdy and easy to get out of for larger people
Cons: Need to give link to cushions available that go with the rocker
