This is a comfortable ergonomic mesh chair which has the ability to recline and adjusts to any height and position you desire. The only con I found was it does not have lumbar support. If it had that I would give it 5 stars.
It's a firm chair because it doesn't have padding but still very comfortable because it gives. Plus it won't absorb bodily odors like those cushion ones. Yup great for farts! :-)
My old office chair was a wreck. I wanted a new one with ergonomic features especially lumbar support. I shopped around on-line but went to brick and mortar stores to try the chairs out. This chair was the least expensive of the ones I'd noted to try but it turned out to be the most comfortable and most adjustable of all of them. This is the most comfortable office chair I've ever used including some pretty expensive ones where I used to work. I highly recommend this chair. Check out the online price versus the store price. The store price was $199.99 but the online price was only $159.99.
This chair is very comfortable and breathable while withstanding being an unwilling cat scratching post. I will say the positioning that the chair allows you to lock it in at is very inconsistent. There's a weird middle ground that would be perfect to have a slight recline in but the chair refuses to lock in at that specific spot whereas it has no trouble locking in any other position. Other than that this chair is a worthwhile purchase when it is on sale.
