Better than expected! Definately worth the money!
I am not one to follow all instructions so I bought this seat so that I could ride with my husband and 18 month old daughter when my family goes on trail rides. It is too difficult to drive and hold her and not secure enough to just hold on to my husband. This seat was a perfect solution. Didn't see the U-bolts in the box at first but after purchasing more we did find them. Installation was pretty straightforward on my Grizzly 600 and we were up and riding in no time. The seat was quite comfortable on straight roads and uphill however on the downhills I found myself sliding off as the pad is a good 1-1 1/2 inches thick. My 7 year old son and 9 year old daughter had no problem staying in the seat (must be their smaller size). The back is quite roomy. Stores 2 chest protectors, 2 helmets, kidney belts, gloves, and still room to spare. Held a nice size cooler along with a days supplies including sweatshirts while we were riding. The arm rests do not open as some and might have been a nice improvement however it is extremely weather proof. After our weekend camping I did learn that if I fold up the bottom of the seat or remove it I was sitting on the actual 4 wheeler seat and had no problems not sliding around. Wouldn't really recommend it for "lounging" however due to the angle of the seat. Extremely comfy for riding however not a recliner. You won't be sorry you invested in this!

Great box at a great price
After searching for a couple months for a rear box for my ATV, I came across this one on amazon. The price seemed too good to be true since most boxes start around $300. I took a chance and ordered it and honestly couldn't be happier with the purchase. This box is very well built, fairly easy to install and has tons of storage space. I installed it on a 2009 Honda Rubicon and it's a perfect fit. The wife says it's comfortable, and friends commented that it looks like it came stock on my ATV since it fits so well. If you're looking for a well made rear lounger with plenty of storage space, this is it.

Big plastic box
Is what it is. A big plastic box. It’s a little on the bulky side but it easily fits two adult helmets and then some. Some edges were pretty rough and needed to be cleaned up with knife and files. Install is tricky unless you have girl sized hands. Once it’s on it is very secure.latches don’t feel all that secure. Without something clipped in to secure them the latches will open on there own with vibration Seat pads are only Velcro. You need to strap or bungee them down when trailering or you will be without a cushion. 5 miles at no more than 45 and it was barely there. Otherwise good quality. Will probably buy another.

Best bang for your buck
This a absolute great buy for anyone that owns a quad and needs extra cargo. Definitely not the biggest or the widest so it won’t make the quad look odd lol. Just the right amount of space for a good day trip. Perfect size to kick back on when parked to enjoy a view. Install is simple and universal with all except maybe Polaris quads. The girlfriend loves it but doesn’t care too much for the seat while she’s riding with me so that’s easily detectable. When riding alone I don’t even use the seat just the back rest. The back resting pad is firm but not uncomfortable. The two latches do not work the best so I put two carabiners in the eyelets to prevent the case from possibly opening. Their isn’t necessarily a great seal but just enough of one to stop 95% of dust and water. That’s what I’m fixing this week the second I get some free time. For just Esthetic purposes this is great and for utility you can’t beat it for the price. Way more room then it looks.

Great for our youngest
Our neighbor has a seat like this for the back of their four-wheeler and works great for their kids so we decide to get one for my youngest you can ride behind now. If you're smaller it also works for an adult because I tried it behind my boyfriend. Was nice and sturdy for him to sit and not wiggle around too much. The only downside was ours came damaged one of the clasps for the hatch was broke but we didn't want to have to go through sending it back so we just have one that locks it. At first we were like there is no way it's going to fit two helmets but it fit two helmets really nicely. This is really nice to have and this one wasn't very expensive but still sturdy.

Broken on arrival
Product arrives with the left strap to the trunk broken off. It looks like a pin that uses a rivet has broken off. Of course we cannot find the pin in the box to reattach. I don’t believe that this will be waterproof or fully secured without both straps to hold it down

Flimsy latches broken upon arrival
Both latches were broken upon arrival there was no way for me to contact anyone to get replacements I didn’t have time to ship it back as I needed it the following day for a ride I would like to get both latches replaced. The box itself is very spacious and my wife likes the padded seat UPDATE!!!!! After reaching out to Kolpin I found their phone number on google they promptly sent me 2 new latches I would highly recommended Kolpin very good customer service.

great quality but uncomfortable
The quality is great, the rear lid is great. The storage is great. It is sturdy, not flimsy or flexy. The rear latches are great. Very good molded plastic parts. The bad is- when they molded the back rest it is at 90 degrees to the seat, so it is very uncomfortable to sit in. The back rest should have been molded at 60 to 75 degrees so you can lean back a little. I had to make a shim from a 2X4 to raise the front so the back rest would lean back. I raised the front 2". This really helped. The cushion are good, but the seat could be thicker. The arm rests are molded plastic, thus hard. Cup holders would be cool. However, I would buy another. Price was good.

Really happy with Price and quality of the box. Ony complaint is no gasket on the rear door. It WILL fill up with dust after a day of trail riding. Two motor cross style helmets do fit but tight! I was looking at used loungers, but this price was excellent for a new one!

Little hard getting the bolt to line up when you have a little bit bigger hands but once all bolted down it works great. Lots of room for helmets or gear in the back.
