This Labor Day, we’re celebrating the people behind the work with something built for them. Grind is a limited edition release created to celebrate the people who keep America moving. Inspired by the builders, tradesmen, and hardworking Americans, Grind combines premium craftsmanship with rugged design.
Available in two colorways, the satin clear powder coat keeps the steel and welds visible, putting the fabrication and craftsmanship on display, while the orange finish offers a hardworking aesthetic. Both feature a distressed brown seat and custom limited edition Grind badge. Built to work as hard as you do.
Satin Clear Finish Disclaimer: The satin clear powdercoat finish intentionally leaves the steels, welds, and manufacturing marks visible. Variations in color, texture, and surface character are inherent to the fabrication process and make each Grind chair unique. These are not defects, but a reflection of the craftsmanship behind every chair.

------------------------------------
The seat upgrade for the rest of us. You're either configuring your first Vyper chair right now and wondering if your frame's going to fit comfortably on a 14-inch round seat, or you've owned the chair for a while and your hips are hanging off the edges by hour two. Either way, the answer is the same. The Big Boy attachment adds 7 inches of seat width and a thick steel base plate that turns the standard chair into the seat that actually fits.
It's not just for big guys, either. Plenty of average-frame buyers add the Big Boy because the wider seat means you don't have to center yourself perfectly when you sit down, you've got more leverage to push off when standing, and the chair feels even more rock-solid underneath you.
Fits: All Robust Steel Max and Elevated Steel Max models, and Robust Steel Pro
Pairs Well With: Adjustable Armrest for the most comfortable Vyper build possible.
Not compatible with the Sidekick
This is only the attachment, not the entire chair

A 14” diameter seat is to small you might want to try a 16” diameter seat on your standard stools, the big boy seat made it really comfortable to be able to sit on it for hours at a time. I am retired and needed the extra leg support I spend most of my time in the garage watching NASCAR and other sports, I saved the box just in case I wanted to return it but that’s not going to happen. Thank you for a great product.
I love the big boy attachment I am a big guy and needed the extra cushion on both side it really made a big difference when I am using it in the garage. Another quality product from Vyper.
Purchased the Big Boy attachment for the taller seat also along with the adjustable backrest. Perfect king’s throne for the shop, just got to keep others out of it now. Planning to purchase the Big Boy attachment for the shorter seat will be a nice add on. Very happy with my choices.
Great customer service! I originally had called with a warranty issue, (the locking mechanism to position the the seat height had worn out), but the customer service person was so nice I ordered an upgrade for my chair!
When I described my chair problem the technician quickly understood and offered sending the replacement parts needed. Then when I considered buying the upgrade parts, he offered to send everything without charging for shipping.
You guys make great products and take good care of your customers after the sale.
It's a real plus that, when calling customer service, I spoke to an agent in the United States. Also a big plus, I'm proud to say your products are made in America! By the way, my co-workers at Honeywell Aerospace are very envious of my chair. In fact, my shop purchased several Viper chairs since I purchased mine.
I already mentioned this in my initial post, but the additional comfort provided by "The Big Boy" seat cushion extension is phenomenal if you spend considerable time seated while working on lengthy projects.
Great chair rolls around perfect in my shop. Glad I ordered the big boy attachment. That makes a huge difference now you got comfort for all day sitting.
Fits like a glove and I love the extra room. Had a friend that was doing some work here and he weighs a little over 300 lbs and he was in love with it and he loves the way it moves around.
Great products,the big boy seat ( I'm not a Big Boy 6' 185) is a must no matter what size you are. If you don't get the tool tray you'll regret it later. I regret not ordering mine with the higher back rest. Overall this chair will last a lifetime and be handed down for generations .
Thank you Vyper for building a quality product made in the USA.
Wheels squeal a little, back hurts after sitting on and working on vehicles almost all day. Back rest could be alot bigger for the price. Otherwise ok.
I added the Big Boy attachment to my Vyper chair, and I honestly wish I had ordered it from the start. The extra width makes a huge difference in comfort, especially during long hours in the garage. I no longer feel like I’m balancing on the edge of the seat, and getting up is much easier thanks to the added stability.
The build quality is exactly what I’ve come to expect from Vyper heavy duty, solid, and clearly made to last. Installation was straightforward, and it fit my chair perfectly. The wider steel base gives the chair an even more stable feel when I’m leaning or reaching for tools.
If you’re a larger person, or even if you just want a more comfortable and confidence-inspiring seat, this upgrade is worth every penny. It transformed an already great chair into the most comfortable shop seat I’ve ever owned. Highly recommended!
I know people that buy these chairs are mechanically inclined but I thought the instruction could have been better illustrated. I bought the chair and arm rests, then added the adjustable back rest and later bought the big boy seat. Just review the instruction with someone on staff that is not handy and see what they see as a challenge?
My husband has been wanting the Vyper chair for his knife shop but would not get it for himself. I went and brought it for him to surprise him. He loves it and can’t wait to start using it! The chair was easy to assemble and the adjustable height will make it easy for him to transition to his different work areas.
I really didn't need the big boy attachment, but the extra room to move and not be on the edge is excellent. I would recommend anyone buying a Viper shop chair to get the extra. It is well worth it.
PUT IT ALL TOGETHER YESTERDAY...BEST GARAGE/ SHOP CHAIR EVER...SMOOTHLY ROLLS OVER THE FLOOR AND EASILY ADJUSTS FOR THE PERFECT HEIGHT FOR MY PROJECTS...
This is a very nice addition to my original stool, both for comfort and safety when you go to sit down. I had a couple of close calls and at 79 your recovery muscles are not as strong and fast as 25.
This is a big purchase. What if I'm not satisfied?

I already have a shop stool, why should I upgrade?
If you're like us, you've more than likely either tipped over from hitting a crack or experience annoying back / knee pain from an uncomfortable stool.
Vyper Chairs (and our entire product line) were strategically designed to help reduce fatigue while working, help prevent from tipping over while rolling, and provide comfort for long working durations.

What is a Vyper limited edition?
A Vyper limited edition is a one-time small-batch run of an existing product (chair, stool, creeper, or cart) in a named colorway, finish, or collaboration design, for example: Ghoul (glow-in-the-dark), Phantom (color-shift chameleon), Sublime (green), Voodoo, Scorch, Joker, Vein, Tribute (military canvas), and Warrior 2.0 (hot pink).
We also have an existing line of collaborations with Vyper x Realtree® and Vyper x Hendrick Motorsports that are always available.
Each limited edition features unique embroidery, custom badges, exclusive stickers and a specific colorway you won't find in the standard lineup. The underlying build (steel frame, casters, foam, mechanisms, capacity, warranty) is identical to the standard product.
Will sold-out Vyper limited editions ever come back?
Once a Vyper limited edition sells out, it does not restock. That's the point, small batch, no second runs. Buyers who miss a drop have to wait for the next release, which will be a different colorway or collaboration entirely.
There are two different styles of limited editions: time based and quantity based.
Some editions we will run where it’s first come first serve (quantity based). Other times we will run a limited colorway for a certain amount of time (time based). If you miss the cutoff, there’s no going back.
Occasionally we will re-release a previously sold-out edition as a special return (for example, "Scorch, Joker, Volt, Shocker and Viola are back" was a one-time encore drop, called out as a last-chance opportunity). But the default policy is one-and-done. If you see a limited edition in stock and you want it, lock it in.
Are limited edition Vyper chairs different from regular chairs in build quality?
No. The build is identical to the standard product. A limited edition Robust Steel Max is the same Robust Steel Max underneath: same powder-coated steel frame, same 3.5" industrial foam, same lumbar-support backrest, same 400 lb capacity, same 5-caster anti-tip base, same lifetime warranty on the frame.
What changes is the finish: custom powdercoat color, custom embroidery, custom badges, and specific accent colors on hardware and stitching. You're getting the same chair Chip Foose, Jay Leno and Gas Monkey Garage use, just in a finish that won't be made again.
Are limited edition Vyper chairs different from regular chairs in build quality?
The fastest way is signing up for the Vyper email list and following @vyperchair on Instagram and YouTube, limited editions are announced usually 1 to 2 weeks before the drop with the exact date and time. Most drops go live at 9 AM CST on the announced date.
High-demand drops frequently sell out within hours. Customers on the email list get the announcement first, which is the difference between getting the chair and not.
Can I add custom accessories to a limited edition chair and do they ship with the same accessories as the standard model?
Yes. Limited edition chairs are compatible with the full Vyper accessory lineup (armrests, backrests, EZ-Lift, Big Boy attachment, tool trays, footrails, Sidekick). Many limited editions offer matching-color accessories during the drop window; once the drop closes, accessories may only be available in standard colors.
