Question for those who use a puma controls from Pro Flight Trainer

I have a pft puma control setup for when I fly helicopters. My trouble is I’ve not found the ideal chair and setup for it. If you use the puma could you please post a photo of your setup to include how you retain the control to the seat. I’m looking for ideas. I got the puma in January while I was traveling in my Motorhome and bought a folding chair, I’ve tried a hunting blind folding chair it was the best position wise but the frame gave way under my bulk. I’ve bought a speedmaster flight sim pit but not everything has arrived yet. I’m looking for ideals to prevent the movement of the controls base other than bolting to the floor either directly or thru the use of a piece of wood.
