The good thing - it was cheap (in price). The bad thing - it was cheap (in usability). The wheels of my chair made indentations in it and it became nearly impossible to roll the chair. What a dumb purchase on my part!!!
I think it will do for now; however I had hoped it would be a bit stronger. The chair wheels make significant dents in it which probably make it less likely to last as long as I would like. The cost was okay but the next one up was too expensive and I took a chance.
The 46 x 60 size is good for my L-shaped desk; I can glide back and forth without the chair wheels going off the edges. Also nice clean edge lines. Hope it lasts for at least 5 years.
