There is no single best Sadhu board. There is a best board for your level, your budget and how you plan to use it. Here is an honest overview of the types you will find, including the ones we do not make.
1. The base
| Base | Pros | Cons | Best for |
|---|---|---|---|
| Birch plywood | Light, stable, does not warp easily, affordable | Less "solid wood" feel | Daily practice, travel, first board |
| Solid hardwood (oak, ash, beech) | Heavy, premium look, long-lasting | Heavier, more expensive, can warp if kept damp | Home use, gifts, collectors |
| Soft wood (pine) | Cheap | Nails can loosen and the surface dents | Not recommended |
| Rubber or plastic | Very light, flexible | Different feel, shorter life | Occasional travel only |
TENGRY boards use ECO birch plywood with three layers of varnish: light enough to carry, stable enough to stay flat.
2. The nails
| Nail type | What to know |
|---|---|
| Copper | The traditional choice. Warm golden look, heavier, develops a patina. Usually the most expensive. |
| Aluminum | Light, keeps its silver color, does not rust. Good value. |
| Galvanized or stainless steel | Cheap and strong. Check that the tips are smooth and free of burrs. |
| "Dynamic" or spring nails | Nails that move slightly into the board. Softer, more forgiving feel, more parts that can wear. |
| Copper-plated | Copper look at a lower price; the plating can wear off the tips. |
At the same spacing, the metal changes the look, weight and price far more than the sensation. Copper vs aluminum in detail.
3. The spacing (the decision that matters most)
| Spacing | Level | Feel |
|---|---|---|
| 8 mm | Beginner | Most nails under the foot, gentlest |
| 9 mm | Beginner to intermediate | Offered by some makers |
| 10 mm | Most popular | Clear, strong sensation, reachable in weeks |
| 12 mm | Advanced | Fewest nails, most intense |
| 15 mm and more | Very experienced | Rare, for specialists |
Why spacing matters so much: in a hexagon grid, a 12 mm board has less than half as many nails under your feet as an 8 mm board, so each nail carries more than twice the load. The physics explained.
4. The pattern
A hexagon (Flower of Life) pattern keeps every nail the same distance from all its neighbours, so pressure is even. A square grid is simpler to make, but the diagonal gaps are wider, so pressure is slightly uneven.
5. One board or two?
Most modern boards are two separate boards, one per foot. They let you adjust your stance, and they interlock nail-to-nail for storage. One-piece boards are simpler but larger to carry.
6. Size
Your whole foot should rest on the nails. Check the maximum foot size before buying; TENGRY boards are about 32 cm long and fit feet up to around EU 46–47 / US men's 12–13 depending on the model.

FAQ
What is the best Sadhu board for beginners?
An 8 mm board with smooth, even nails on a stable base. 10 mm also works for confident beginners who start in socks.
Is solid wood better than plywood?
Not for the practice itself. Solid wood looks premium and weighs more; good plywood is lighter and stays flat. Nail quality and spacing matter more.
Are steel nails bad?
No, if they are smooth and level. They are cheaper and look plainer than copper or aluminum.
