Surprisingly good! I rode 250 miles, about 4 hours, in the rear seat, and got out feeling fine. I wanted to see what I might be offering to family members if we need to put adults back there. It's been strictly 11 years old and under back there until now. Leg room was the tightest fit, but doable. I'm 6', with a 33 inch in seam. I was worried about the lower cushion not extending out under my leg toward my knee very far, but it didn't bother me. Of course, your mileage may vary!
