Hey! I have those. Originally used for my DXRacer chair. I put them on my Embody after recieving. I don't recommend it. It left deeps indents into the cushion of the chair that took about a week to get out. (I only left them on for 2 minutes too, most likely because it's squishing the cushion inwards because it's too tight)

I think the Embody arm rest is fine too but I needed just a bit more height... since my table was a lot taller than expected to chair.
