Customer Reviews
Overall rating: 4.8 / 5 from 232 reviews.
So far the best shop chair I’ve ever had and would highly recommend this stool It rolls easily and is the right height for what I do p
Well, I can't use this wheel lock because I ordered my chair several weeks ago and I have no idea where it is. Order says it's still processing. Frustrating.
I've had four major back surgeries over the past 12 months, with the last one being a 4 level fusion of my lumbar spine. The Vyper Chair has allowed me to return to my wood shop and work comfortably on projects. Everything about this chair is Top-Tier, right down to the stitching in the leather seat. Adjusting the optional back rest is intuitive and the CNC knurled knob is massive, which allows you to adjust the angle while sitting in the char. Setting the cushy back rest to the right height is super easy to accomplish, thanks to the oversized adjusting knob. The locking rolling casters actually work, are well engineered, although a bit cranky at first. I applied a small amount of silicone lubricant to them, which made them silky smooth to engage and disengage. The wide stance of the chair makes it extremely stable. I purchased the Elevated Steel Max, due to my 32" high shop benches and it has more than enough height adjustment, allowing me to dial the seat height in to my liking. Everything about this chair screams 'Made In America'. It's a chair that will outlive you, the kind that gets passed down to the next generation of makers, mechanics and maintainers. It has given me back the ability to work in my shop, all day long. It's worth every single penny and void of 'buyer's remorse'. You will never regret purchasing one. Ever!
I already sent this via email. The quality of what was shipped did not match the ones that came with the stool. Very disappointing as the lock never engages the caster. You could ship 3 caster locks that match the original ones that came with the stool.
Stool and casters are an outstanding p -design and appearance is amazing, built for a lifetime!! Thanks and didn’t go wrong by purchasing!!!! Ron Gaertner
My floor is very erratic (old house) . I needed more braking to keep the chair stable and in place at my bench. Works a lot better now..
Poor quality. Poor instructions, Nut did not fit supplied bolt. Poorly milled. Had to buy new bolt and nut at Lowes. Instructions do not show that folded steel tab on lock must fit into slot on existing wheel. This kit is VERY DIFFERENT QUALITY than the Vyper chair, which has outstanding quality, fit and instructions.
I wish my chair would of came with this option 6 years ago when I bought my first vyper chair really handy feature.
Great product, and I did order the easy lift chair, and I ordered the kick, the tool tray, and the adjustable back, rest, and Two Wells, and also the arm rest. But when I ordered it, they failed to tell me that the armrests is not compatible to EZ lift chair. So now I have to mail it back and then get reimbursed. I’m gonna say, I do love my EZ lift chair.
I think your chairs are made extremely well and they look amazing. Unfortunately, I returned the chair because they are not comfortable or supportive. You need to make the seat square with more length and width to support your legs. The back rest is tiny and does almost nothing. You should make the back rest noticeably larger in width and especially height so it really supports your back/lumbar etc. If you did that, you would have the best stool ever made. I ended up buying a Uline adjustable stool that has a seat and back support as I mentioned even though it is not made anywhere near as well as Vypers. Thanks
Awesome accessories to add to the hyper chair
My Vyper shop stool wasn't very stable in my garage shop which has a coated floor. Even with two wheel locks, the other three wheels would move slightly which made the stool a bit hard to climb onto. I ordered two additional wheel locks which did the job of making the wheels easy to hold steady in place. It would seem natural that all five wheels would have locks for such a high-quality shop tool like the Vyper.
Tw0 wheels cracked and began falling apart. So I went to Vyper's website and ordered 2 new 4" wheels with locks. In turns out I ordered just the locks. I contacted customer support, explained my problem. Photos where requested and submitted. I received an email not long after, advising me two new wheels would be shipped. I received the wheels about three days later and put them on. I was not surprised because Vyper manufactures great products, built to last. Customer support matches their products, absolutely awesome. So if you are reading this review, attempting to decide whether this chair is worth the money. For sure, without a doubt! One other thing, so is their Customer Support Team. FIVE STAR
It does what it is supposed to do. You can apply it and it stays and unlock it with ease and move accordingly.
My floor is a bit rough.These 4" casters roll much better.
Easy install. Locks wheel securely, easy to operate.
Are you kidding me? This righteous shop chair is adding years onto my life and quality of workspace. The only question I have is why I didn't I purchase Vyper years sooner? Thank the heck out of you!!
Works greak, recommend all future rolling devices come with at least on brake
Good construction. Price is way too high for what this is.

We like the chairs we purchased but wished we knew about the Joker version you were about to make available. Very sweet design.
Absolutely love these wheel locks! Thanks Vyper!!
Very easy to install and works as it should
As you can see, I love my chairs so much that I put them inside as my Island chairs for enjoying television and eating dinner
I was disappointed in the seat because it didn't have the logo on it I order it to replace the original seat that got burn t from rolling in to heater I think u have a quality product but the replacement part should be just like the original. thank u for being concern. Gary Gillespie
Great chair. The model did not give permission to use the photograph with her initials
Great chair, just wish the butt pad was a little farther away from the backrest. Looks killer. Stitching color contrast is awesome.
Luv the brakes but should be included in purchases it rolls away to easy on my driveway almost dangerous…..Highly recommend that you include with low pro…
I'VE USED THE WHEELS TO REPAIR/UPGRADE SEVERAL OF MY CUSTOMER'S TOOLS; A TOPSIDE CREEPER WITH WORN OUT WHEELS AND A MINI MOBILE TOOL BOX/SEAT THAT HAD JUNK WHEELS ON IT. WORKED FANTASTIC ON BOTH. JUST LIKE THE MANY VYPER CHAIRS I'VE SOLD, THE WHEELS ARE TOP SHELF.
Great chair but some rubber wheels options would be nice as well as a thin rubber mat option on the bottom tray (robust steel sport is what I have) so the tools don't make so much noise when your wheeling around.
The lock is either off or all locked. Wish it had a resistance setting so I could move the chair but it wont roll away.
I initially had some concerns because I had some outdated casters that were not compatible with the locking mechanism; however I was able to update my current chair with outstanding and prompt Customer Service (kudos to Bryan). The locking mechanism is simple but effective and it assures my wife that she will not see her disabled vet rolling out the sloped garage. Semper Fi Ben J.
great chair -- very sturdy -- A lot of money for a chair but well worth it --
These are simple to install, and work as they are supposed to. I felt I needed more than the two that were included and sure enough the extra locks gave me the solid feel I was looking for.
I do like the wheel lock. I am disappointed that I had to pay almost $40 to buy 3 more locks so the elevated steel doesn’t move. I think it should come with locks on all wheels. I do love my new chair though and look forward to many years with it!
Great addition because the chair is so smooth.
Excellent quality!!! Very organized packaging and easy to follow instructions for assembling.
Awesome chairs!
This was needed as I have a sloped driveway and have had to chase my chair several times after getting up.
Frequently Asked Questions
Everything you need to know before you upgrade.
What accessories are available for Vyper chairs and stools?
The most-purchased Vyper accessories are the Adjustable Backrest, Adjustable Armrest, Big Boy, Tool Tray, and Sidekick. Each one solves a specific problem:
- Adjustable Backrest: Replaces the stock backrest with a 10° tilt and 4" of height adjustment, for buyers who want to dial in lumbar support exactly.
- Adjustable Armrest: A solid grip for sitting down and standing up, and most importantly, to improve posture / stability.
- Big Boy: Adds 7" of seat width, for larger frame buyers or anyone who wants more room and stability.
- Tool Tray: Bolts to the underside of the chair to hold sockets, loose bolts, and shop rags.
- Sidekick: Side-mounted attachment with cup holders, a tool holder, and storage for spray bottles, polishers, and shop towels.
All accessories are made in Green Bay, Wisconsin and ship with the same warranty and 30-day guarantee as the chairs themselves.
What's the difference between the Sidekick and the Tool Tray, and do I need both?
The Sidekick mounts on the side of the chair for what you're actively using (spray bottles, polishers, microfibers, a cold drink), while the Tool Tray bolts underneath for what you've already used or what might fall (loose bolts, dropped sockets, shop rags, small parts).
They're built to work together, not against each other. Detailers and fabricators who run the Complete Package (Robust Steel Max + Tool Tray + Sidekick) consistently say the two-accessory combo turns the chair into a real mobile workstation. Sidekick at hand for the polisher you're using right now, Tool Tray below for the spent microfibers and parts. If you can only pick one, the Tool Tray is the accessory most buyers later say they wish they'd added from day one.
Can I use the Big Boy and the Sidekick together on the same chair?
No. The Big Boy and the Sidekick cannot be installed on the same chair, they mount in the same location and you have to pick one. Our specialists at (920) 301-3822 can walk you through the right choice if you're not sure.
The decision is usually clean. If you're a larger-frame buyer (or an older buyer wanting more leverage when standing), get the Big Boy. If you're a detailer, fabricator, or anyone who works with supplies at the seat all day, get the Sidekick. The Adjustable Backrest, Adjustable Armrest, and Tool Tray all work with either choice, so you don't lose any other accessories by picking one over the other.
Is the Adjustable Backrest worth the upgrade over the stock backrest?
For most buyers, the stock backrest is built right and works exactly as designed. The Adjustable Backrest is the upgrade for the buyer who lives in the chair, taller height range, up to 10° of recline, and the ability to dial in the support position to your specific body and the way you actually work.
Roughly half of buyers add it during initial chair configuration. The other half buy it months later, after deciding they want to fine-tune the backrest position even further. Reviewers consistently describe it as the upgrade that turns the chair from "comfortable" into "I never want to get up." Compatible with the Robust Steel Max and Elevated Steel Max chairs, and pairs with either the Big Boy or the Sidekick.
Who should buy the Big Boy attachment?
The Big Boy adds 7" of additional seat width, built for two specific buyers: larger-frame customers (280 lbs and up, or anyone who finds the standard seat too narrow) and older buyers who want more leverage when sitting down and standing up.
Reviewers consistently call it a confidence upgrade. The wider seat means you don't have to perfectly center yourself when sitting, and the wider surface gives you something to push off when standing. It's the most-recommended upgrade in the Vyper review base for buyers in their 60s, 70s, and 80s. Available on all Vyper chairs except the Low-Pro and Robust Steel Sport. Cannot be combined with the Sidekick.
Can I add Vyper accessories to a chair I already own?
Yes. Every Vyper accessory is designed to bolt onto chairs already in your shop, you don't have to buy them at the same time as the chair. Roughly half of buyers add accessories during the initial chair configuration. The other half buy them weeks or months later, after deciding what they actually need.
The Tool Tray, Sidekick, Big Boy, Adjustable Backrest, and Adjustable Armrest all install with basic hand tools and ship with instructions and hardware included. If you bought your Vyper chair years ago, the accessories from today's lineup are still compatible with the standard chair models. Call (920) 301-3822 if you're not sure whether an accessory fits an older chair.
Which Vyper accessories work with the Low-Pro and Robust Steel Pro stools?
The Vyper Backrest add-on works on the Robust Steel Pro and the Low-Pro Backrest works on the Low Pro, for buyers who started with a stool form factor and decided they wanted lumbar support after the fact.
The Big Boy is not compatible with the Low-Pro, but is compatible with the Robust Steel Sport. The Tool Tray and Sidekick are designed primarily for the Robust Steel Max and Elevated Steel Max chair frames. For a stool-specific tool-holding solution, the Robust Steel Pro ships with a built-in stationary tool tray as a standard feature, no add-on required.
