Comfortable seat/storage box

I have a lady friend that has been riding with me. I tried letting her ride my spare quad but she just isn’t into it.:icon_ cry:I currently have a Plano 1510 and love it but it’s a little cramped. But she loves riding on back with me so I’m looking at a more comfortable storage box with a seat. The 2 I like the looks of are the following:

1) Anybody have any experience with the Kolpin lounger (link below)?

2) The other would be the Quadboss Weekender. This one is about $370 vs $195 for the Kolpin.

Any input for these or other seats is appreciated!

Thanks guys!
