High-quality wood dining tables are often solid wood rather than composite or veneer, which makes them more durable and less prone to warping. Check for even, well-joined seams without visible gaps, as well as sturdy, solid legs or pedestal support. The finish should be smooth and consistent, with no rough spots. Lift the table slightly if possible; quality wood tables feel substantial. Avoid tables that feel hollow or have rough, unfinished edges. Reliable manufacturers often provide a warranty, which can indicate confidence in their product’s quality and longevity.
