About the Manufacturer

Started in 1995, OFM is a family-owned furniture distributor with an eye on consumer satisfaction.

After working for years as a furniture manufacturing sales representative, Abel Zalcberg saw a market opportunity for a furniture company that could have faster delivery times by keeping inventory in stock. Using personal savings, he and his wife Barbara set up an office in their home, printed up a catalog and sold chairs from vendors Abel had worked with in the past. They believed that quick delivery—take an order in the morning, ship it the same afternoon—would set their young company apart. The plan worked and the company is still known for its fast shipping.

Today, OFM is a thriving operation that specializes in providing affordable furniture to general businesses and government offices, as well as schools and hospitals.

The chair quality is great. 

from Cleveland, OH – Verified Buyer

The chair quality is great.    The service is great.   The pricing changing regularly and not staying consistant is my issue mostly because an employee goes on your site gets a price - has to get it signed off and days later I get it to buy and the price went up a lot.    Or someone ordered a chair and paid 250 for it - a second employee sees it and gets it approved for himself assuming that the price within a week/months time would be the same instead it was over $300.   I know that is the "deal" you offer but it can be frustrating because of the price increase I have to go thru the approval process again hoping my cart remains.    Thanks.

The Ultimate Chair

from New York, NY – Verified Buyer

I have to say, this is my 3rd purchase from Wayfair. I am pleased with all orders. Regarding this OFM 24HR. Chair, it is amazing! It is everything described. All my parts were present in shipping, the box was undamaged (this was not the case with some other customers here. The lack of better instructions left me 4 Stars. I had to read some instructions twice for accurate assembly. However, with that said the chair was a breeze to assemble and the many custom adjustment are a dream. I sit at my home office at least 4--5-6 hours working on various projects and this seat give me long comfort throughout my work load. My legs no longer tingle, or my rear no longer falls asleep. The well padded seat is "hard/very firm" at first but you get used to it over time. If in doubt-try it. I don't think you'd be sorry.

Finally What I Wanted

from DeLand, FL – Verified Buyer

This purchase was for my office chair in which I sit in front of a computer 9-10 hours per day. I wanted multi-adjustments and this OMF brand chair has all of them! I had bought two other brand chairs +$300 and returned both. They were either defective or not as advertised. I am 6' and this chair has such a big range of adjustments in all areas it should fit anyone. Specifically I wanted seat forward & backward tilt, seat depth adjustment, and good height range as I like to sit high. It is near perfect. Heavy duty & attractive, too. I HIGHLY recommend it!

Great Chair for Extra Strength

from Windsor, ON – Verified Buyer

Some people need a larger and stronger chair. The normal chairs bought for offices are not meant to support larger people. So this is a great alternative to the office challenge, and it ties in nicely without looking like a huge chair. Most people won't even notice it is a larger chair. Needs assembly when it arrives, so be sure to check all your parts and follow the instructions.

I am happy with it

from Brookhaven, PA – Verified Buyer

Honestly it took to shipments for me to get pieces that we not damaged and I didn't feel like going for a third one when both had scuffed seat and back cushion. (this was a shipping problem) I was home and didn't know they delivered or I would have refused shipment both times. Wayfair has done EVERYTHING POSSIBLE to it right with me and I appreciate that. The chair went together fairly easily (the casters were a little hard but not to big a problem) The directions we standard and easy to follow. The chair is comfortable I would have preferred it to have a slightly larger cushion but it is nice. My kids like to sit on my lap when I am at the computer and with the weight this char is meant to handle it is no problem to have them sit with me and as the arms go out some there is to accommodate the slightly more space needed as well. I think the gray fabric is nice too.

Great chair!

from North Berwick, ME – Verified Buyer

I purchased two of these chairs for staff use at the circulation desk in our public library. The staff users couldn't be happier. The chairs are sturdy(!), comfortable and easily adjustable for individual comfort.

Resident meteorologist

from Fulton, NY – Verified Buyer

Just got it, and it is wonderful. Easy adjustments, and very flexible. Quite comfortable, and the only thing I can't comment on is durability because I just got it. So far, I would highly recommend this.
