Review: 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!
Review: 6 years going strong - I have had this box on my 2009 Polaris Trail Boss for over 6 years. Everyone in my family rides, and we have all agreed that this is by far the best box for storage, passenger comfort, and sturdiness. Not once has the box shifted or moved at all, even when the quad gets tipped on it's side. There are barely even any scratches on it. Also, I've never gotten water in the box from rain, so anything inside is always perfectly dry. The fact that the arm rests come so far forward makes it extremely comfortable for passengers, big or small. It feels very secure for kids, acting as a kind of seat belt. The kids will often fall asleep back there, and as long as I slide back a bit, there is little risk of them falling off. I did remove the bottom seat pad because the kids said it wasn't comfortable, so now they just sit directly on the Polaris seat. Of all the machines, my siblings want to ride with me because this is the most comfortable of all the box/seats we have. My one complaint would be that the latches are kinda junky. I wish they were more metal than plastic. One of the latches broke off about 3 years ago, but the one remaining latch is holding tight and I'm not at all worried about it coming loose. If my box ever breaks, I am definitely going to purchase another one of these. It is incredibly reliable, and the amount of storage inside is amazing! Totally worth the money.

### ⭐⭐⭐⭐ Great Storage! Fantastic Storage! Buy it for the Storage! Has a few quirks.
*by D***N on July 3, 2017*

As far as storage goes, this is it! I was able to fit 5 thin jackets, my first aid kit, a small plastic bin with snacks, water bottles and 3 small "lunch sized” coolers in it with a bit more room. The install on our ’04 Honda foreman was 1.5-2 hours. Hubby is handy. He had to take the rack off to install it. I’m giving it high ratings because the storage is unbelievable. But here are some quirks. **The latches don’t stay closed. I was able to find a small carabiner that kept it latched well. **Don’t forget to take the seats off while traveling. We lost them somewhere on the road. We will attach the replacements with small screws. **I would recommend carrying water bottles in a container rather than throwing them in loose. They jostled around and hit the bolts, which put holes in our bottles. **We “break the rules” (gasp) and ride double. My husband and son (who are 5’9”) loved it. My adult daughter and I, who are 5’4” and shorter, didn’t love it. We couldn’t touch our feet and we kept sliding out. The hand grips didn’t help hold us back, since we were already sliding forward. We couldn’t reach over the arm rests to grab the rack (we are short). I ended up coming down a steep hill holding onto the back of the box and trying to balance on my tip toes. Not the most comfortable way to ride when you have a 2nd seat. I finally just sat on the main seat behind my husband, pushing him into the handlebars. In hindsight, some of those issues may have been our fault. Here are our plans to solve the dilemma. 1) We believe the seat is at a 90 angle, but our rack slopes down. We will reinstall with some shims on the front to make it tip back more. 2) We may have installed it too far back. We will move it closer to the driver seat so our feet can touch. 3) We may consider installing passenger foot pegs. 4) We may create some handles to attach to the rack that we can reach over to hold us sideways. So, the quirks may not be with the trunk as much as they are the ATV's sloping rack and the short people. The storage is amazing, and according to the manufacturer, that’s why we buy it-NOT to ride double. Once we take care of the quirks, I think we will love this trunk.
