The item was too thin. Mat does not work well for short shag carpet. The wheels of chair still sank into the mat causing it hard to move the chair around. The mat needs to be thicker or not so soft that wheels of chair sink into it causing Indentations in mat.
This was a great solution for a double door leading in and out to the back yard. It serves as a landing on new carpet when coming from gardening outside.
It’s functional but I’m not sure how long it will last as it is very thin plastic. I had a card table leg on one corner for about a week and it left a big deep dent in the plastic mat.
