It is bolted to Brey Krause side mounts which are bolted to the floor with the floor mount with integrated sub bar.
I also have an out of date Sparco Circuit pro halo seat that you may be able to use with a back brace. It is good for slender people, my butt can fit in the base but my shoulders are too wide for the wings/halo. The bad thing about seats is they are so big, shipping is $$$, so it is best to sit in one first unless you know someone your same size with the seat.
