I bought this for my mother who is not comfortable using the rise function in her Recliner chair; the arm supports are a little low when she was trying to stand. Firstly, it is so simple to put together, actually very sturdy and the thing I was most concerned with, was how it will fit into the chair - well, it fits snugly into the seat and it is not noticeable when seated. The support posts have really done the trick. This an excellent product, which I researched across the internet. Huge thanks to your company!
