How we scored them
The Office Score weighs performance (stated pile rating, weight limit, thickness), build (size, material, edges), value for the stated specs, safety and warranty. For high pile carpet, safety means a stated certification; one of the five states one. One states a warranty term: the ES Robbins with a limited lifetime warranty. How we pick explains the weights.
| Product | Office Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best chair mat for high pile carpet
Match the mat to the pile
Not every mat here is rated for high pile. The ES Robbins states it is essential for extra-high pile carpets more than 1 inch thick including padding, with an Anchor Bar cleat system and a 0.2 inch thickness. The Koonmi tempered glass mat states a 1000 pound limit on a 0.19 inch glass surface. The KAISLE, at 0.14 inch thick in PET, states carpet use but no pile rating. The GORILLA GRIP and Yoshiko both state low pile carpets, so they are the wrong pick for deep carpet despite being in this lineup. For thick pile options, see our chair mats for thick pile carpet.
Material, size and weight limit
| Mat | Size | Material | Stated weight limit |
|---|---|---|---|
| ES Robbins High Pile Chair Mat | 46 x 60 in | Vinyl | 200 lb |
| Koonmi Glass Chair Mat | 46 x 55 in | Tempered glass | 1000 lb |
| KAISLE Chair Mat 48×36 | 48 x 36 in | PET | Not stated |
| GORILLA GRIP Chair Mat | 29 x 47 in | PET | 400 lb |
| Yoshiko Chair Mat 36×48 | 36 x 48 in | PVC | Not stated |
The ES Robbins at 46 by 60 inches is the largest here, with a beveled edge and a stated 200 pound limit for intensive use over 8 hours. The Koonmi glass mat at 46 by 55 inches states rounded corners, polished edges and a detachable anti-slip pad. The GORILLA GRIP at 29 by 47 inches includes a lip and states spikes on the underside for low pile rugs. The KAISLE ships flat, which avoids the curl of rolled mats. For medium pile, see our chair mats for medium pile carpet.
Warranty and certification
The ES Robbins states a limited lifetime No Crack Mat warranty and GREENGUARD certification for low chemical emissions to UL 2826, plus made in the USA. The other four state no warranty term and no certification. A stated lifetime warranty on a vinyl mat is the strongest promise in this lineup, since plastic mats are the ones that crack. For quality options, see our quality chair mats for carpet.
Setup Notes
- Measure the pile with padding: the ES Robbins states it suits extra-high pile over 1 inch thick.
- Glass mats need the anti-slip pad in place before the chair goes on.
- Flat-shipped mats like the KAISLE lie flat immediately; rolled mats can take days.
- Low-pile mats on high pile carpet will rock and crack, per the listings.
