We have 3 Lazy-Boy recliners - the oldest has 'real' wood in the framework. The middle one and with the most troublesome reclining mechanism is a mixture of real wood and OSB. The newest - sighhhhh - all OSB that I can see when turned over. The price of each was at least incrementally more expensive for less quality. We have a Lane recliner in the RV - it was the least expensive but is by far the most robust vs the last two Lazy-Boys. Any top line furniture store will have good furniture still made with real wood, the rest of it is what I call ground cardboard (low end MDF) held together with nails and staples.
Good luck on the next five. Their repairs should all go faster then the first with the vertical learning curve
