Product description
The Boss Diamond Task Chair (B9091-CS) is a mid-back ergonomic task chair built for productivity and all-day comfort. Its contoured back promotes proper posture that helps prevent back strain, while extra large seat and back cushions deliver comfort across a full workday. The chair is upholstered in black antimicrobial vinyl, a surface that resists microbial growth and wipes clean — making it a practical choice for healthcare environments and other settings where hygiene matters.
Functional adjustments include adjustable arms, pneumatic gas lift seat-height adjustment, and adjustable back height and depth, so the chair can be dialed in to the individual user. The chair rides on a 25-inch nylon base with dual-wheel 2-inch nylon casters and supports a weight capacity of 275 lb.
The B9091-CS carries MAS Green certification and meets CA TB117-2013, and it is available in four colors to match an existing color scheme.

When it comes to delivering a satisfactory customer experience, the staff and owner at Miramar Office Furniture OVER-delivers.
Even with a last-minute request that was far from simple, they created the possibility to complete our order in excellence and made the entire process enjoyable.
With their support, my team has been able to help restore and renovate a project for very close to our hearts with the San Diego Center for Children.
If you are looking for a reliable business, you're in the right place. Thank you, Miramar Office Furniture!

We recently got some furniture delivered and put together at our office in Miramar and the guys were so nice and polite. They were fairly quick, but I was most impressed by how helpful they were and made sure that my director of operations loved where they placed the furniture and how it looked before they left. They even offered to move it if he changed his mind. I feel like that hard to come by nowadays so thought I'd leave a comment.

The store specializes in office furniture, so if you're looking for office items this place is worth the time, more than the average furniture store. We found exactly what we wanted at this store for a good price. Very friendly staff overall, and Bodhi's mom was so helpful and accommodating.
