FURNITURE FRAMESTOCK OF PARALLEL-LAMINATED VENEER 



Particleboards and fiberboards have become major competitors of lumber 

 cores and plywood for the flat surfaces of furniture and fixtures. Structural 

 frames for upholstered furniture (fig. 22-16 top), however, require the strength 

 generally found only in lumber. Upholstered-furniture frames are generally 

 produced from No. 2 Common or frame-grade mixed hardwood lumber. Al- 

 though oak is preferred by many manufacturers because of its greater strength, 

 weaker species such as yellow-poplar are also commonly used. Appearance is 

 not a factor since the frame is hidden by upholstery. Defects included, however, 

 must not reduce structural adequacy.
