  • Great for short folks
I'm 4'8" so finding a chair that doesn't contort me into a shrimp is tough. This chair was surprisingly well fitted for me. My back lines up perfectly and the mesh is super comfortable to sit on. Which means it's probably a little too small for the average sized person but y'all can't have everything. It rolls around just fine and the pistons work as intended, and the weight is just right. My only complaint is the fixed armrests are a little too low, even for me. ... show more
