++1 this ^^^^ you can score some great chairs for cheap.
If you want new, I have had great luck with "church chairs." They seem to be a bit more expensive then I remember, but worth looking in to. Two recommendations:
1. Go with the wider 21" wide seat option.
2. If available, go with thicker foam. 2" and 3" foam flattened after a couple of years for me, but the 4" thick ones I have held up great.
Good luck!!
