When you have 3 or more seats at the same height it's nice to have some flat area (all the same height, contoured) This looks a little restrictive? Have you sat in it and stretched out?
Viking are more value designed, but solid, easy to fix, maybe a bit less efficient. Maybe a bit less longevity. Seems a bit high to me. 6 grand? 6500? But if it's a solid dealer that provides services you can use?
