Too thin for use on the thinnest commercial glue down carpet. Save yourself the trouble a spring for the better (thicker) one. My husband bought it because it was 50% off. Now we know why.
We may have to return this because it affects my allergy-based asthma. The off-gassing has lasted a week and is diminished but not gone. Otherwise an adequate product.
I bought this to use under a desk. The chair that sits on top of it is very light and has hard plastic casters. It is being used by my child that weighs under 100lbs.The product has dents in the material from the chair. It is very hard to roll on top of it! I am not real pleased with this product.
