Materials are chosen to behave well, season after season. White oak, American black walnut, ash, and hard maple are paired for tone and figure, allowed to rest to the shop climate, then milled on calibrated machines so parts meet cleanly. Surfaces are sanded in quiet passes under dust capture and finished with low-odor, home-safe coats that protect the surface while keeping the natural feel of wood—good for homes with children and pets.

Proof of capacity is part of the work. Shelves are tested at the span you choose, wall sets are checked for torque and pull-out on real substrates, and hinges and slides are torqued to spec and cycled for quiet travel. Numbers printed on a page come from trials on finished pieces, then ride along in the packet that ships with your order.

Stock is real, not a promise. A Ready Rack in the back room holds core models in standard sizes and finishes, refreshed on a steady cycle. When an in-stock piece is chosen, Tsunsport confirms, packs, and hands it to the carrier the same business day during working hours. Labels print in the studio and tracking is shared immediately. If a fitting comes up short, pre-staged spares keep the schedule intact. This is how Tsunsport proves there is product to ship today.

Sourcing stays clear and verifiable. Lumber is purchased through long-standing U.S. mills and distributors with documented custody, and motion hardware comes from makers with U.S. operations—Blum, Accuride, Häfele, Sugatsune, KV—so smooth movement and long service can be supported for years. Lot codes live in the job file, and documents are available on request.

Design and build share the same room. Proportions are taped on the floor, quick mockups settle reach and height, and only then does the first board meet the blade. Faces and edges are jointed and planed true, panels are glued with balanced grain, and joinery matches the task: mortise-and-tenon, floating tenon, dowel, or threaded inserts that respect seasonal movement and future service. Finishes go on in thin, even coats with a full cure window—no rushing the last step.

Quality is written down by hand. A traveler card follows each piece from material pull to machining, dry fit, surface prep, coating, assembly, hardware set, and clean down. Corners, diagonals, and key dimensions are logged, and no crate is sealed without a final sign-off.

Packing is careful and calm. Edges are guarded, faces sit in soft cradles, and parts are numbered in the order you will install them. Heavy cartons are double-wall; long frames ride strapped pallets when needed. Labels print in house and tracking goes out at once, along with an unboxing checklist that shows what to inspect and how to reach Tsunsport immediately if anything looks off.

Care is easy to remember. A soft cloth, no harsh chemicals, space from radiators and big humidity swings, a little airflow around panels, and felt pads under feet for floor safety and leveling. For wall pieces, use anchors rated for the substrate as listed in the guide. When sheen softens after long service, a light maintenance oil brings it back.

Service answers in specifics. Notes through the contact form usually receive a reply by the next business day (Mon–Fri). Shelf pieces leave the day they’re ordered during business hours. Made-to-size work enters the queue at once and typically completes within a few weeks depending on finish and fittings. **Quotes are itemized—wood, hardware, finishing, and freight—**so choices stay clear and costs remain readable.

The guarantee is plain. If a problem begins with Tsunsport or happens in transit, Tsunsport will repair, replace, or refund. Steps and time frames sit in short, direct language on the Warranty and Returns pages—no fine-print traps.

Before the first cut, Tsunsport helps picture the room. Finish swatches can be mailed, fast 2D/3D previews can be shared from your photos or measurements, and practical notes on heights, overhangs, cable paths, and shelf spacing arrive with your draft. The goal is simple: quiet furniture that does its job and feels good to touch.

Tsunsport stands for made to be repaired, not replaced. Standard parts, spares on hand, and hardware you can buy again keep service possible years from now. The shelves are stocked, cartons are staged, the carrier stops daily—Tsunsport is ready to ship the moment an order is placed. Reach out anytime for sizes, finishes, anchors, or installation plans and expect specific answers, not scripts.
