I have 2 pairs(ie 4 seats) of 2011 Toyota Sienna seats in grey cloth. My rear set has only ~2weeks of use on them, front set has a few months of use if that. Both were brand new 0mileage takeouts so they're in superb condition. They recline and the seat bottom folds up to the seat back(this is how I'm able to swivel the RF seat).
If you're looking to install these in a Ford E-Series van, the Sienna seat mount brackets are available from Chris at UJoint Offroad, and fit some of the factory bolt holes(you'll need to drill the other side in the floor); http://www.ujointoffroad.com
If you want to install these in a different vehicle, the UJOR seat mount brackets will still bolt to these seats, and so you'd just need to bolt the seat brackets to the floor--easy.
Seats are like these;
Some pics here in my van here;
They are VERY comfortable. I had been looking for new Sienna leather recliners and finally found some, so will installing them instead.
Seats are $249/pair. Can ship, but prefer local pickup(Portland, OR).
LMK if you have any questions.
