  • 6 years going strong
Edition: CHAIR
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. ... show more

  • Better than expected! Definately worth the money!
Edition: CHAIR
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! ... show more

  • Best bang for your buck
Edition: CHAIR
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. ... show more

  • Rear seat??? Or tool box??
Edition: CHAIR
I bought this seat for my lady for when we go on rides because i know i don't riding on a rack and would want some back support. She had mixed reviews but thats expected if you know what i mean. What was unexpected is that i figured i'd have to take it off around deer season but i've found it useful for holding all my stuff when i go to hang stands so everything doesn't go rolling off when hit a bump or rut. I've never rode in the seat but the seat pad isn't a mattress but is pretty mud and dirt resistant once you give it a spray off. Attaching it to the rack was fairly simple but i did add 2 extra sets on u-bolts to the very front to make sure it doesn't recline. Worth the money??? If it last 10 years to me it will be and it seems well built out of good material so barring any accident and being garage kept i think it will. ... show more

  • Great for our youngest
Edition: CHAIR
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. ... show more

  • Stiff seat pads
Edition: CHAIR
One star. Product was not as described regarding specifically the fit and finish was a mixture of shiny and dull, the latches in rear were completely different and unable to secure. What looks like padding on the arm rest is just molded plastic there is no pad there. The pads to the seat look great but we’re silver instead of black as in the description and the comfort level is similar to sitting on cardboard you can feel the sharp stiff edges in your back nothing lounger about this padding. Now is there a positive in all this? Sure tons of storage although it’s just one big unorganized compartment and the door might flip open while riding Everything about this product is a scam and the people who are reviewing it on YouTube must be crazy to ignore all these flaws of which most are not due to quality control but instead just a poor designed deceitful looking product ... show more
