Wood, plywood and composite board bases
В мені · VMENI · Updated · 2 min read
A sadhu board base may be solid wood, plywood or another structural material. Solid wood offers a natural grain and species-specific properties; plywood consists of bonded layers. Assess either by flatness, integrity, nail fastening, weight and the manufacturer’s care instructions rather than by the material label alone.
Solid ash, oak and walnut
Wood species affect texture, colour, mass and price, but the name does not verify the finished board. Look for cracks, distortion and unfinished edges. Engraving or decorative inserts should not interfere with the product’s purpose.
What to check in plywood
Plywood is layered wood. Bonding quality, edge condition, separation and compatibility with the fastening matter. It is inaccurate to call all plywood short-lived or all solid wood reliable purely by category.
Thermally modified wood
The term describes wood that has undergone thermal modification, not simply a dark stain. Colour alone cannot verify the treatment. Check the actual material and product specification; do not assume every treated species has identical properties.
Finish, moisture and cleaning
Oil, wax and varnish have different care needs. Find out which products are permitted and whether renewal is needed. Do not soak a base by assumption. “Moisture-resistant” is not permission to immerse a complete board.
Choose without paying only for a name
For home storage, consider size and upkeep; for carrying, compare the full set’s weight. If appearance is important, look at the actual piece of wood. On a limited budget, fit and workmanship matter more than a prestigious species. Claims about a wood’s energy are not a verifiable specification.
