Toyota Sienna, fits 8th seat in 2nd row

Toyota Sienna, fits 8th seat in 2nd row
Previous reviews were unclear if this was going to work but the profile of the seat looked promising, so I gave it a shot. I can fit 3 backless booster seats across the 2nd row of my 2014 Toyota Sienna LE 8 seater (i.e., 2 captains chairs and one removable 8th seat). My kids prefer sitting together and I prefer to have them in this arrangement as well. The buckle to the middle seat is difficult to reach for my 4 year old but they make devices to stand the buckle up (and I've read you can use a cut off pool noodle as well). My 9 year old helps the young one buckle up and so it ends up working out. The handle on the right of the Cosco seat also obstructs the ability of the right captains chair from buckling easily but they manage. My other two kids have Graco backless boosters with cupholders. If they had Cosco seats it's possible that it would crowd less ... Regardless, I want to inform the Sienna driving world that it works!!! My 4 year old totally digs it.
