Grain, color and finishes

Variation of grain and color are natural, inherent characteristics of wood, a living material. This variation is part of the beauty of realwood and anticipated in wood veneer furnishings. Therefore, Proline II furniture is not warranted to match in grain or color or texture. It is a natural phenomenon for wood grain to change in color as it ages, and wood finishes are not warranted for colorfastness.

All warranties are limited to the original purchaser for normal commercial usage defined as a standard forty hour work week bypersons weighing 250 lbs. or less. The 54666 is for persons weighing 300 lbs. or less. The 7103M, 7602R, 7605R, 7600R, 81108, 81308 & 81608 are for persons weighing 400 lbs. or less.
