Keep Your Belongings Safe
It’s time to trade in that milk crate for a storage solution that’s as serious about off-roading as you are. SuperATV’s Rear Cargo Box for the Polaris RZR PRO XP is the perfect add-on to protect your belongings on outings of all kinds. This hard-sided container can easily be installed on the back of your machine and will keep your gear safe, cool, and dry. With its carbon steel exterior, quick-sealing lid, and heavy-duty latches, our Rear Cargo Box offers reliable security and convenient features, all rolled into one sturdy product.
For All Outdoor Pastimes
Most outdoor adventures don’t lend themselves to traveling lightly. Whether you’re packing extra ammo for hunting, a tackle box for fishing, or camping gear for a weekend away, the Rear Cargo Box’s 30-liter capacity gives you all the storage you need. It’s also perfect for carrying an extra change of clothes or spare tools for whatever job needs done.
Don’t need to tote around all that extra gear? Even if you’re just out for a casual joy ride, chances are you’re going to get hungry or thirsty. For times like this, you can fill the box with ice and let it double as a cooler. The lid and sides are packed with insulation (almost four inches of it in some parts!) so your cold-cut sandwiches and brews will stay chilled all day long.
Rugged Steel Construction
Every inch of this cargo box is designed with durability in mind. We know that when you’re in the midst of off-road exploring, the last thing you want to worry about is whether or not your stuff is going to get ruined (or worse, end up flying behind you onto the trail). The lid is engineered to keep out dust and debris, and the rugged steel construction makes the box totally weather-proof. This means you can safely store everything from snacks to clothes, even in miserable weather conditions, and trust that they won’t come out dirty or soggy.
Convenient Features
The lid of this box has two built-in cup holders, giving you a nice place to set your cans when you stop for lunch or a late-night snack. There’s also a plug on the back to make cleanup a breeze, especially if you’ve packed this thing with ice for the day. Just unplug, drain, rinse, and voila—it’s ready to be packed up for next time.

Comfortable chair that works great for long hours
Color: Black
I’ve been using this office chair for a few days and it’s been very comfortable for working and longer desk sessions. The high back design and ergonomic support help maintain good posture, while the cushioning stays comfortable throughout the day. The chair feels sturdy and stable, and the 330 lb capacity gives it a solid, durable feel. It also rolls smoothly and quietly, which is nice when moving around the workspace without creating a lot of noise. Overall, it was easy to assemble, looks professional, and offers great value for the money.

Very Comfortable Ergonomic Chair - Great for Long Work Days!
Color: Black, Color: Black
I’ve been using this ergonomic office chair for a couple of weeks now and I’m genuinely impressed. For the price, it offers excellent comfort and support.
What I like:
• Very comfortable padded seat and backrest — I can sit for 8+ hours without back pain.
• Good lumbar support and adjustable height/armrests.
• Holds up to 330 lbs easily (I’m 240 lbs and it feels very stable).
• Smooth rolling wheels and sturdy base.
• Easy to assemble (took about 20 minutes).
The mesh back breathes well and doesn’t get hot. It looks professional in my home office too.
Overall, this is a solid ergonomic chair. If you spend a lot of time at a desk, I highly recommend it.
Would I buy it again? Yes, definitely.

Great if you're average height.
Color: Black
Comfortable for the price. The seat could be a bit better, but for a budget friendly ergonomic chair, it's well made and has helped a lot with my back pain caused by my previous desk chair.
Assembly wasn't terribly difficult, though I did have one screw with damaged threads. Luckily they ship spare screws in the kit, so that was a non-issue.
Rollers work great on my small rug and hard flooring and don't tend to tangle cords or cables too much.
Size wise, works great for my frame (5 ft 6 in) but for someone more than a few inches taller than myself, you should probably look at another chair.

Great chair
Color: Black
I am very happy with my purchase. Easy to assemble but be aware your drill bits included with your set won't fit their screws. However, you can get a fair bit done with the drill and then use tool included to adjust. Super comfortable and exactly the right height for my desk. Highly recommend for quality exceeding price point.

Review from an "actual" tall person who doesn't weigh 400 pounds.
Color: Black
I recommend this chair.
Firstly, I looked at least dozens of chairs and nearly every review in trying to select a chair. I didn't want to spend $200.
It's confusing because everyone's idea of perfect is of course subjective. One thing, What is tall? I'm 6'6" I think that's pretty tall. Others feel that 6'0" is tall. LOL In the listing, it shows this chair is good for a 6'5" person which I think is pretty accurate. I weigh about 210 pounds and the padding is just fine. One thing I would push manufacturers to do would be to give accurate measurements. Seat height low and high. Back support height. Head rest added to back height etc.! Maybe actual human measurements that the chair is geared toward. Nice to know that 400 lbs is cool but that doesn't tell me much.
My primary goal was to find a chair I could sleep in because I recently had a
back injury and sleeping on my bed, while fine, resulted in intense pain trying
to get up in the morning. We'll see what happens but the headrest reaches my head
which was goal one.
The lumbar fits so I don't need to use cushions and pads etc. I found the upper
position of the support to be right for me and it's super comfortable. Plus number
two.
The raised height of the chair fits my long legs (inseam 36") Plus three.
I wanted adjustable arm rests but this one doesn't have that. No biggie, for me the height of the arm rests is pretty much just right. It might be a little high for some.
The back leaning adjustment doesn't lock except for upright. Locking upright is good, and leaning back - for me - doesn't really need to lock.
Being an actual tall person made me really skeptical. I'm relieved that I won't have to take it apart to return it. The assembly was straight forward and pretty easy though I'd suggest not really tightening the arms snugly before getting the back squared away - the alignment is easier if you do that.
I got the chair for $109 with 21% off. It's slightly wobbly yet feels pretty well made. It rolls well enough.
I'm quite satisfied with the purchase and I'll come back if there are updates.
Edit one. I've had it a week now and found I couldn't sleep in it. I think it would be better if the back could recline separately from the seat. There might also be figuring out a way to support my legs due to the back and seat reclining together rather than separately. Two. I kind of wish more now that the arms were adjustable for height and tilt if that makes sense. I have a bar stool next to me on the right in front of my desk that is the right height to relax my right arm while reaching my mouse on the desk so that's my work around there. Three. The casters are kind of basic and don't roll as easily on the floor matt as my former second hand chair - they would probably be fine on a hard surface. I'll probably switch them out. Four: The lumbar support, while mostly in the right place is unpadded and creates kind of a hard spot there. I've re-introduced my lumbar support pillows for comfort there.
All in all, I'm still happy with the $100 purchase. In my experience, being pretty tall always comes with compromise and these notes are not deal breakers for me.
Yea, It can always be more perfect but unless you're in a showroom test driving and willing to spend $300? Right.
UPDATE: I'm really not satisfied with this chair and in fact, I wish I hadn't bought it. Firstly, the pneumatic post that the chair part connects with is wobbly depending on which way it is facing according to which way the legs are aligned. It's like a poor fit and I'm pretty mechanically inclined.
Second and also important. The lock to keep it upright and inclined only worked for a few weeks. For a while, you had to mess with it to engage the upright position. It no longer works.
Worse than that, the lumbar support pad disconnected with the chair and is now floating and after only a month or so, the remaining supports for the Lumbar rest have dug into the fabric on the back of the chair creating holes in the back's fabric. I've tried but there is no way to reconnect that bit without removing the back's fabric as far as I can see.
I'm taking this down to one star for sure. Poor design? Poor manufacturing? Yea. I wouldn't suggest this chair to anyone. If the company comes up with a solution, I'll continue my review.
As for now. Not a recommendation.
Update: Not impressed and kind of crappy. Mentioned is that the so called lumbar thingy disconnected and is unusable. I've got my own pad which seems to help. Also, it's wiggly where the chair connects to the base. Months later, I might toss it and go back to the chair I bought locally and second hand.
Don't buy this chair!
