5 of 5 Great cargo box/ Seat February 24, 2020
Reviewer: Steve Reisert from Port Mayaca Florida  
This seat is great for the Polaris Spirtsman.  The lock n ride system was just what I wanted.  You have the ability remove and reinstall with ease.  Instructions for installation were not so great.  I removed the plastic rear rack and used it as a template for my drill holes.  Box does not come with pre-drilled holes for lock n ride system.  Once holes are drilled n rack reinstalled mounting seat to rack is a breeze.  Also be prepared to assemble seat as it does not come preassembled.  Just got back from a muddling event, “Plant Bamboo” and I could not be more pleased.

5 of 5 Love the seat! July 10, 2018
Reviewer: Steve from Southern Maine  
The seat is great, my girlfriend loves and and thinks its great.  Shes always cold so the handwarmers are a big plus.  Plenty of room in the compartments and it has a real high quality appearance.  The gas tank holder is great for peace of mind when we are out in the back country and dont know when there is going to be another gas station.

5 of 5 Love it love it love it! June 26, 2018
Reviewer: Nicole from IL  
We purchased this box for me to sit behind my husband. It is very comfortable on longer rides. I love how there is space on the back for our cooler and plenty of storage on the inside for extra clothes and gear. It's also nice that I do not have to get off to access the storage since it opens on both the left and right side next to me. The cushions are nice and thick. Fits great on our 2018 Sportsman 570. Once installed easy on and off and very solid. Thank you Thor and TheATVSuperstore for all your help. It is nice to still recieve true customer support and knowledge on products you sell.  We will be back soon for a 2nd box for our Sportsman 500! Cheers, Nicole
