Depends on the quality of the veneer and substrate. Many high end antique furniture is veneered but solid cheaper wood underneath.

My bedframe is almost 800 lbs, just the 16 inch wide oak rails take 2 people to move, and I was quite surprised to find out it has thick veneers with laminated MDF underneath on the corner posts. When I chipped it I was disappointed to find the MDF, I had always assumed it was solid wood and it was sold as such pretty expensively too. I had no problem fixing it and it's still beyond sturdy built like a tank and survived multiple moves including hired movers knocking a hole in a wall getting it down some stairs once.

Our previous bedframe was a solid wood hand me down with metal rails and it was thin and broke beyond repair, hence the super beefy replacement.

Dont assume its BIFL just because its solid wood, and not because it may have some veneers.
