I used to use a couple pieces of wood to hold my pedals and chair in place when sim racing. It wasn't a perfect set-up, as the wood ended up splintering into the carpet and it just looked awful. It wasn't even that stable, if I'm honest, but that's what was required to prevent my load-cell pedals slipping under heavy braking. This sim racing mount should help alleviate that issue.
It's called the SR Pedal Stand Pro from SR Rigs. It lifts up your pedals to a more suitable position for racing and extends underneath a user's feet to hold a gaming chair in place. The casters of the chair slot into a locking system and there's a strap to prevent a chair from tilting under heavy braking.
