I had given up hope on my last chair that I had had for years because the suspension wore out. This chair has already starting breaking down and I have only had it a short time.
This is actually a fine chair all the features you would want comfortable bottom and back support. It is sold at a fair market price compared to other sources I looked into. I use this chair 5 days a week. I purchased nearly one year ago I notice no wear no breakdown of support. I would purchase again if and when the need arrises.
I would give the "Staples Mcallum Bonded Leather Managers Chair Black" a 4-star and a great choice for me. The product was a reasonable price and meets my office needs.
