Perfectly sized and design for my home office needs - it allows my chair to roll, but not roll away - and easily vacuumed.  
The 1-star deduction is due to the sides of the rug, that are curling up a bit and allows for dirt to roll under the rug.  It's a bit irritating, but I'm hopeful it will lay flat after a bit of time.  Fingers crossed!
Note for anyone sensitive to scents: There was a bit of off-gassing when first unwrapped - not terrible, but noticeable.
