I use this as a mat for under our highchair on wheels. It allows the highchair to roll smoothly where it was otherwise difficult to move on bumpy textured carpet. It makes clean up of fallen food much easier. I don't have to worry about carrots staining the carpet! The one thing I would change is the size. I would have liked it to be a little bit bigger. Other than the size I'm very happy with this product.
I'm thinking that Staples may have shipped the wrong thickness mat to me. I'll have to get my digital calipers out to check but it seems a lot thinner than .130 ...... More like .85 by the looks of it unless they count the small pegs as part of the thickness. If this is the case I'll be getting in touch with them really soon!
I purchased this more expensive chair mat ~18mos ago hoping it would last longer than the cheap one but it started getting grooves & cracks fairly soon. My carpeting is not that thick but I still have to replace the mat much sooner than expected so I'll go back to the cheaper one. It's not worth the extra $$$ (+I cut my foot on one of the cracks!)
