The try before you buy concept is our idea as well. Unfortunately the showroom is 1200 miles away. We plan to be near that area next winter so may stop by then.
We are also looking for a new one for the house. Unfortunately we have not seen anything that really lights our fire so far. One thing that we do like about the one shown in shop4seats is the console and USB outlets inside, we also really like the swivel tables on the arms. Just have not been able to find anything similar in the local furniture stores or on Amazon or lazy boy sites.
None of the ones we have found so far have the arm trays or a console that folds up out of the way when not needed.
The return policy on the shop4seats one makes it impractical to buy it without trying it in our view.
