Quality

 
Form pressed plywood shell chairs are strong and durable .. if manufactured correctly from quality raw materials.

Shells made of short fibred  wood like birch- or rubber wood  are likely to twist.

Shells with exterior plies of melamine (lacquered paper) does not withstand hard use as well as wood plies. Melamine surfaces are practically impossible to repair if damaged.

2 mm gauge steel tube frames are required for long life and hard use.
