Types of Wood for Furniture: Suar, Acacia, Driftwood and Tembusu Compared
The best types of wood for furniture range from affordable tropical hardwoods to rare heritage species, and the right choice depends on your budget, the room's conditions, and how much daily wear the piece will handle. Hardwoods like walnut, oak, maple, and cherry remain the top tier for durability and classic appeal. But several lesser-known species deserve attention, especially for buyers looking beyond the standard North American and European options.
Suar, Acacia, driftwood, and Tembusu each bring distinct advantages in grain character, hardness, and price point. CITA Interior, a solid wood furniture maker specializing in Suar hardwood at citainterior.com, works with three of these four materials regularly. This guide compares their properties so you can match the right wood to your next furniture project.
What Makes a Good Furniture Wood?
A good furniture wood balances hardness, grain stability, moisture resistance, and workability. These four properties determine how long a piece lasts, how it ages, and how well it accepts a finish. No single species excels in every category, which is why different types of wood for furniture suit different rooms and purposes.
Hardness is measured on the Janka scale, which records the pounds of force needed to embed a steel ball halfway into the wood's surface. The USDA Forest Products Laboratory publishes standardized hardness data for commercial wood species. Higher numbers mean greater scratch and dent resistance. Teak, one of the hardest commercial furniture woods, scores 1,000 to 1,155 lbf.
Grain stability determines how well a board resists warping. Woods with interlocking grain patterns hold their shape better across humidity swings. Straight, tight grain also sands and finishes more evenly.
Moisture resistance varies widely between species. Some woods, like teak and acacia, contain natural oils that repel water. Others need a protective coating to survive kitchens and bathrooms. For a detailed comparison of sealing options, see wood finish types.
Workability matters for complex joinery. Softer woods carve easily but dent faster. Harder species hold fine detail but require sharper tools and slower cuts.
What Is Suar Wood?
Suar wood comes from the rain tree (Samanea saman), a tropical hardwood native to Central and South America and now cultivated extensively across Southeast Asia, particularly in Thailand and Indonesia. With a Janka hardness of 900 lbf (comparable to African mahogany), Suar delivers moderate durability at a fraction of the cost of teak or walnut. It is CITA Interior's primary furniture material.
Color and Grain
The heartwood ranges from golden brown to dark chocolate, often with darker streaks that create strong contrast across wide slabs. Sapwood is thin and yellowish-white. Grain is typically straight but can interlock and wave. These variations produce the distinctive organic patterns prized in live edge wood furniture. Rain trees grow up to 30 meters in urban settings and 60 meters in natural habitats, so their trunks yield large-diameter slabs ideal for single-piece dining tables and wide shelves.
Strengths
Suar's interlocking grain resists warping under normal indoor conditions. High resin content provides natural termite resistance and eliminates the need for chemical treatment. The species grows readily and matures quickly, which makes it more sustainable and affordable than slow-growth hardwoods. Planks typically range from $7.90 to $60 depending on thickness. Maintenance requires only soap, water, and a soft cloth.
Limitations
Improper kiln-drying leads to splitting, warping, and mold. Spills and stains show easily on lighter-toned slabs, so coasters and prompt cleanup are essential. Suar also lacks the water and rot resistance of teak or walnut, which rules it out for outdoor use without extensive sealing.
When shopping for suar wood furniture, verify the wood's origin. Thailand and Indonesia produce the highest-quality lumber. Test the slab's stability on a flat surface and examine the finish closely. Excessive lacquer sometimes masks wood that was not dried thoroughly.
Best Uses
Dining tables, coffee tables, solid wood table tops, floating shelves, live edge console tables, and statement headboards. Suar is the best type of wood for furniture where you want a large, visually dramatic slab at a mid-range price.
Is Acacia Good for Furniture?
Acacia is a strong choice for both indoor and outdoor furniture. The species most common in Southeast Asian production, Acacia auriculiformis (known in Vietnam as "tram bong vang"), combines exceptional durability with fast growth, natural pest resistance, and a grain pattern that shifts from deep brown to golden honey depending on the cut.
The wood rates durability class 1-2 (very durable) with a raw density of 0.69 to 0.79 g/cm3. That density sits between oak and maple, so acacia has enough hardness for heavy daily use on dining tables, kitchen countertops, and flooring.
Unlike Suar, acacia has genuine water resistance. Natural oils within the wood repel moisture, which explains its frequent use in outdoor garden furniture, cutting boards, and kitchen bowls. The wood also carries natural antibacterial and hypoallergenic properties, a useful trait for surfaces that contact food.
Growth rate sets acacia apart from most hardwoods. Trees grow 6 to 8 feet per year, so the species qualifies as a renewable resource that does not deplete old-growth forests. Rapid regeneration keeps pricing competitive with mid-range softwoods.
For upkeep, wipe acacia surfaces with a soft cloth and warm soapy water. Avoid silicone-based or ammonia-based cleaners, which strip the wood's natural oils and dull the surface over time.
What Makes Driftwood Different from Other Furniture Woods?
Driftwood is not a species but a category: any wood shaped by prolonged water and weather exposure. This natural weathering process alters the wood's density, texture, and structural integrity. The result is a material fundamentally different from freshly harvested lumber in both appearance and performance.
Prolonged submersion leaches tannins and softer fibers from the wood. What remains is a harder, lighter-weight shell with a distinctive silvery-grey patina. The process also introduces cracks, knots, and smooth, wave-polished edges that give each piece a one-of-a-kind profile. No two driftwood slabs share the same shape.
These qualities come with trade-offs. The leaching process weakens internal fibers unevenly, so structural load capacity varies piece to piece. Every driftwood slab requires thorough inspection, cleaning, and treatment (typically kiln-drying and sealing) before it can support weight as a shelf, tabletop, or bench. Salt deposits from ocean exposure must also be removed to prevent finish adhesion problems. For methods on protecting wood furniture from moisture, proper sealing is especially critical for reclaimed pieces.

What Is Tembusu Wood and Why Is It Rare?
Tembusu (Fagraea fragrans, family Gentianaceae), also known as Ironwood or "gỗ trai" in Vietnamese, is a premium hardwood classified in Vietnam's Group I, the highest tier reserved for rare and precious species alongside agarwood and rosewood. The tree grows slowly, lives roughly 100 years, and produces extremely hard, dense lumber prized for heirloom furniture and traditional crafts.
Physical Properties
Tembusu trees reach 10 to 25 meters tall with trunk diameters of 0.7 to 0.8 meters. The bark is dark brown to black, and the wood itself is a vivid natural yellow. Grain is flexible yet dense, and this combination gives Tembusu exceptional resistance to termites, warping, heat exposure, and moisture. Vietnamese royalty historically used Tembusu for palace furniture and ceremonial items, a tradition that still shapes the wood's reputation.
Three Varieties
The yellow variety (called Trai vang in Vietnam) grows across Southeast Asia, reaches 10 to 30 meters, and produces bright yellow lumber suited to large furniture pieces. A second variety sourced from Singapore and India (Trai ly) grows 25 to 30 meters with a darker, more pronounced grain. The red variety (Trai do) features reddish-brown veins, a glossy smooth surface, and a distinctive swirl grain pattern. Of the three, the red variety commands the highest prices.
Pricing and Scarcity
Round logs over 30 cm in diameter cost 4.5 to 5 million VND per square meter. Sawn timber longer than 3 meters runs 7.5 to 8 million VND per square meter. Government regulations now restrict harvesting strictly because natural populations have declined. This scarcity, combined with the tree's slow growth cycle, positions Tembusu as a luxury material unlikely to become more affordable.
Best uses include high-end dining sets, display cabinets, religious and ceremonial items, and collector-grade accent furniture.
How Do Suar, Acacia, Driftwood, and Tembusu Compare?
These four types of wood for furniture occupy very different positions across the price, durability, and sustainability spectrum. Suar and Acacia offer the most accessible entry points for solid hardwood buyers. Driftwood suits decorative and sculptural pieces. Tembusu is the premium choice for buyers who prioritize hardness and rarity above all else.
| Wood Type | Hardness | Moisture Resistance | Best Use | Price Range | Sustainability |
|---|---|---|---|---|---|
| Suar | Janka 900 lbf | Low to moderate (indoor only) | Dining tables, shelves, live edge pieces | $7.90-$60/plank | High (fast growth, easily replanted) |
| Acacia | Density 0.69-0.79 g/cm3, durability class 1-2 | High (natural oil content) | Indoor/outdoor furniture, kitchenware, flooring | Moderate | High (grows 6-8 ft/year) |
| Driftwood | Varies by original species and weathering | Low (requires sealing) | Decorative shelves, accent tables, wall art | Varies (sourcing dependent) | High (reclaimed, no harvesting) |
| Tembusu | Extremely hard, dense flexible grain | High (resists heat and moisture) | Heirloom furniture, ceremonial items, luxury dining sets | 4.5-8M VND/m2 | Low (slow growth, government restricted) |
For buyers searching for the best wood for dining table use, Suar and Acacia offer the strongest combination of slab width, durability, and value. Tembusu delivers unmatched hardness but at significantly higher cost and with limited availability. Driftwood works best as a decorative accent rather than a primary dining surface because of its variable structural integrity.
How Does CITA Interior Select Its Wood?
CITA Interior sources primarily Suar hardwood for its furniture collections. Each slab is evaluated for grain character, structural stability, and consistent drying before it enters production. The company also works with driftwood and Acacia for specific product lines, matched to each piece's intended function and the customer's design goals.
Every Suar slab that enters CITA's workshop goes through a kiln-drying process calibrated to the slab's thickness and moisture content. This step prevents the splitting, warping, and mold that affect improperly dried tropical hardwoods. After drying, craftsmen inspect for hidden voids, grain irregularities, and stress points before any cutting begins.
Suar remains CITA's primary material for three reasons: the grain produces wide, visually striking single-slab surfaces, the wood accepts oil and lacquer finishes evenly, and the price allows customers to own solid hardwood furniture without the premium that teak or walnut commands.
For driftwood pieces, CITA cleans, treats, and stabilizes each reclaimed slab individually before shaping it into furniture. Acacia appears in products that require higher moisture resistance, including outdoor-rated items and kitchen accessories.

Frequently Asked Questions
What is the most durable type of wood for furniture?
Among the four woods in this comparison, Tembusu (Fagraea fragrans) is the hardest and most durable. Vietnam classifies it in Group I alongside agarwood and rosewood. For more widely available options, teak (Janka 1,000-1,155 lbf) and Acacia (durability class 1-2) both deliver long-term performance suitable for high-traffic furniture like dining tables and kitchen countertops.
Is Suar wood good for dining tables?
Suar wood is one of the best choices for dining tables, especially large single-slab and live edge designs. Rain trees produce wide trunks that yield slabs spanning over a meter across. At Janka 900 lbf, Suar resists everyday scratches and dents while its interlocking grain pattern minimizes warping indoors. Use coasters for hot dishes and wipe spills promptly to prevent staining.
Can Acacia wood be used outdoors?
Acacia wood performs well outdoors because of its natural oil content, high density (0.69-0.79 g/cm3), and durability class 1-2 rating. The wood resists pests, fungi, and moisture more effectively than most hardwoods in its price range. Apply a UV-protective oil annually to prevent greying from sun exposure and avoid direct ground contact to extend the wood's outdoor lifespan.
