Gibraltar GUBR universal Back Rest

This is a decent back rest, sturdy, good quality, and looks nice as well. Very easy to install. The only problem I have with it is that I can't install it to the sliding stem of my drum throne as I use it at the minimum height settings - so I had to attach the back rest to the stem just below the legs - and the attachment this way is too far down for the back rest to reach up to the optimal height, so it's sitting quite low now at waist level. If you have about 5cm clearance just below the seat cushion that's a continuous cylindrical spot, this should work fine.

Comme à son habitude. Du Gibraltar tout simplement.
