What is QSWO (Quarter Sawn White Oak)?

Most of our furniture is available in QSWO and we receive a lot of requests for information on the difference between quarter sawn white oak and regular red oak.  The most common oak lumber used in furniture building is plain sawn (or flat sawn) oak and all the boards have been cut straight across with the cut being parallel to the tree’s growth rings.  This method highlights the swirls, lines and grain of the wood.

Quarter Sawn & Plain Sawn Wood


Quarter sawn lumber is cut at right angles the growth rings and this results in medullary rays, sometimes called “ribbons” or “tiger stripes”.  Producing QSWO requires more time and skill than plain sawn oak and aside from being visually appealing, quarter sawn wood has some structural advantages.  As quarter sawing produces a straighter grain, it yields wood that is more stable in size & form (less susceptible to cracking, warping, bending) than plain sawn wood.  Quarter sawn wood actually stains more readily and resists liquids better than plain sawn wood.
