My experience carries the weight of the over hundreds of pieces I've built and restored over the years. Some of them were from the 20s. Some of them were over 200 years old. That's all.

I'm telling you that a high quality particle/veneer/wood combo piece has a better chance of holding up changes in temperature, pressure, etc, than a hardwood piece. I'm not talking about 200 year old furniture. I'm talking about now. With the practices we use now. You want to mortise and tenon a table for "stability"...go nuts man. But when it comes to large panels, I'll say it over and over and over again, you have less of a chance of that panel shitting over the years if it's a giant piece of good quality particle and high end veneer.

Also no one veneers hardwood anymore because it's stupid and wasteful. You need to put the same type of veneer on the seen and unseen sides, and finish them the same way because I guarantee you (because I've seen it happen), if you don't it'll warp the piece. With particle board this is much much much less likely to happen.

I never talked about making chairs. Because I don't make chairs. That's a profession all its own. And I doubt any chair-maker would use particle or MDF to make their chairs, unless they're trying to make something particular. In which case it might be used for a back rest or a piece that'll be upholstered.

I said pressed wood and particle or MDF because they're the industry standard. You want to use a good quality plywood...like baltic birch, fine. But it's not a lie and not untrue when I say that composite materials are more stable than hardwood. This is a fact.

Also a piece made of particle, when done right, veneered, won't get mushy over time. And no one will even be able to tell (unless they're trained to look for it) that it's made from particle board or MDF or pressed wood, or plywood. I get that you want to argue with me about this but the fact is that composite materials are more stable, and when used with proper techniques generally last longer and warp less than wood pieces.
