Glide I have heard are good seats, however I think I would choose a Wise Guys Seating instead. The prices are pretty close but the Wise Guy has a bench frame with a swing-down arm rest. They come with:
Center Fold Out Arm rest
2 Recliner Release Points
2-12 Volt Power Receptacles
16 Gauge Steel Frame
Foam Fabricated w/Multi-density Foam Types
No Sag Springs
Split Back
7" Slides
Risers

I saw one in a 50 AD yesterday was very impressed.
