Rubi SR1 Ergonomic Knee Pad Seat

It's worth every penny! I had to lay over 1000 sq ft of 20" porcelain tile (10 lbs each) for my last project. I used knee pads in the past but I was in pain, I ordered this and what a difference! If you are tiling anything other than a small area, you need this seat. It really makes those jobs that are so hard on the knees and back much more comfortable and much less painful. It's very well built, aluminum chassis, rolls easily, very stable, has plenty of room and support in the knee area and makes things so much easier. It also reduces the time spent moving from site to site on the floor to just a quick ride, so job is done much faster. I highly recommend SR1 of Rubi, it saved my knees, back and shoulders!
