Ready-to-Assemble Furniture Kits, Panels, Fittings and Cartons
Ready-to-assemble kits for desks, bookcases, cabinets, beds and storage, delivered as machined panels or solid wood parts with fittings, hardware pack, instructions and carton.
Ready-to-assemble furniture ships flat and is put together by the end buyer with a hardware pack and a printed guide. The wood is only part of the job. An RTA furniture manufacturer machines the panels or solid parts, bores every hole so parts meet without adjustment, counts and bags the hardware, writes the assembly steps and packs the kit in a carton that survives parcel delivery.
Most of the cost and most of the returns come from three places: hole accuracy, missing or wrong hardware and transit damage. A kit with perfect panels still gets a one star review if one cam lock is missing or a corner is crushed. Factories that do RTA well treat the carton and the hardware pack as part of the product.
Species and panels
- ParticleboardThe standard core for melamine faced RTA panels. Low cost and flat. Weak at the edge, so fittings matter.
- MDFSmooth faces and edges for painted, foil wrapped or shaped parts.
- PlywoodStronger and lighter than particleboard at the same thickness. Used for higher end kits and visible ply edges.
- RubberwoodStable plantation hardwood for solid wood kits and legs, often edge-glued into panels.
- Radiata pineLight, low cost softwood for beds, shelving and kids furniture kits.
- AcaciaHard, dense and figured. Used for solid wood tables, benches and shelving kits.
Types of RTA furniture kits
Name the type on the RFQ. Factories that make one type well do not always make the others.
| Type | What it is | Fits |
|---|---|---|
| Panel kits | Melamine, foil, laminate or veneer faced particleboard or MDF, cut, edge banded and bored on CNC. | Desks, bookcases, wardrobes, TV stands and storage sold at value and mid price points. |
| Solid wood kits | Edge-glued or solid parts in rubberwood, pine or acacia, machined and finished before packing, joined with bolts and cross dowels. | Beds, tables, benches and shelving where buyers want real wood at a parcel friendly size. |
| Mixed kits | Solid wood frames or legs with panel tops, backs and shelves, packed as one kit. | Desks, dressers and cabinets that show wood on the frame and use panels where they do not show. |
| Multi-carton items | Large items split into two or more cartons, each labeled box 1 of 2 and so on. | Wardrobes, bunk beds and long desks that would exceed parcel size or weight limits in one carton. |
Typical specifications
Starting points used across the trade. Your drawing sets the real values, and each factory confirms what it can hold on the quote.
| Spec | Typical value | Note |
|---|---|---|
| Panel thickness | 15 to 18 mm for carcass panels, 3 to 6 mm for backs, typical | Give the core type, face material and edge band on each part. |
| Boring system | 32 mm line boring, front setback about 37 mm, typical | Keeps shelf pins and fittings on a shared grid. State it if you use another system. |
| Hole position tolerance | About ±0.2 mm on CNC boring, typical | Cam and dowel holes that drift by 1 mm stop the kit from going together. |
| Cut size tolerance | About ±0.3 to ±0.5 mm on panel length and width, typical | Tighter on parts that sit between two sides. |
| Edge banding | 0.4 to 2 mm PVC, ABS or wood veneer band, typical | Name which edges get band and which stay raw inside the carcass. |
| Carton weight | Up to about 70 kg (150 lb) per carton for parcel delivery, typical carrier limit | Lighter cartons cost less to ship and break less. Set a target weight per carton. |
Typical values, not a guarantee. Confirm every value that matters to you on the quote and the approved sample.
How it is built
- Cam locks with dowelsA cam housing in one panel pulls a bolt in the next panel tight, with wood dowels for alignment. The common fitting on panel kits. Allows taking apart and rebuilding.
- Cross dowels and boltsA metal barrel nut set across the part takes a long bolt through the joining part. Stronger than a cam on solid wood beds, tables and frames.
- Confirmat screwsStepped screws driven into a pre-bored hole in the panel edge. Strong and low cost, but less tolerant of repeated assembly.
- Pre-assembled sectionsSome parts such as drawer boxes or doors with hinges ship assembled to cut assembly time and errors. Weigh this against carton size.
Finish options
- Melamine or laminate facedDecor paper or laminate pressed on the panel. No finishing after cutting, only edge banding. Ask for the decor code and a sample.
- Painted or lacqueredMDF or solid parts sprayed and cured before packing. Ask how finished faces are protected from rubbing in the carton.
- Oiled or lacquered solid woodSolid parts finished to a color sample. Ask for the finish system and a color range across lots.
How RTA furniture kits are made
The usual process chain, from dried lumber or panels to packed goods. Ask which steps happen in-house and which go out to another plant.
- 01Kiln dryingFinal moisture content, internal stress and how much the part moves after delivery.
- 02Rough millingHow much clear wood you pay for, which defects reach your parts and how evenly the color runs.
- 03Finger jointing and edge gluingJoint strength, water resistance, how visible the joints are and whether panels stay flat.
- 08Veneering and pressingThe grain pattern of every veneered surface, how flat the panel stays and how its edges look.
- 05CNC routingShape accuracy, hole positions for hardware and how well parts from different batches fit together.
- 09Joinery and assemblyHow strong and rigid the product is, how square it stands and how it ships.
- 10Sanding and finishingColor, sheen, smoothness and how well the surface resists heat, water and wear.
- 11Inspection and packingWhether the goods that leave the factory match the order, and whether they arrive in the same condition.
Who orders RTA furniture kits
New kits usually start with samples, a test assembly by the buyer and a carton test before the first run. Volume orders run by the container per item. Many plants set a minimum per item and color, since each decor or finish is a separate setup.
E-commerce furniture brands
Sell mainly online and ship by parcel. They care about carton size, weight, damage rate and an assembly guide that cuts support calls.
Retailers and importers
Buy RTA lines for stores and their own sites by the container. They care about cost per cubic meter and repeat quality.
Office and student housing suppliers
Need desks, beds and storage in volume that installers can put together fast on site.
Rules that may apply
- TSCA Title VI and CARB Phase 2 limits apply to particleboard, MDF and hardwood plywood in kits sold in the US
- Dressers and chests sold in the US must meet the clothing storage unit tip-over rule under the STURDY Act (ASTM F2057-23), including a tip restraint and warning label
- Parcel shipped cartons may need to pass ISTA 3A or another transit test your carrier or sales channel names, so state it if you need it
- EUDR due diligence for wood placed on the EU market
What to send for a quote
With these points stated, every matched factory quotes the same product.
- Drawings or 3D files of the item with every part, its size and material
- Fitting type and hole positions, or permission for the plant to propose them
- Face material, decor or finish and the edge band per edge
- Hardware list, or ask the plant to supply and count it
- Carton limits: size, weight, number of cartons and the transit test you need
- Assembly guide: your file, or ask the plant to draft one
- Quantity per item and color for the first order and the yearly volume
What to check on samples
Approve one sample in writing and keep it as the reference for every shipment.
- Full test assembly of a kit pulled from packed cartons, using only the guide and the bagged hardware
- Hole positions against the drawing on several parts per batch
- Hardware pack count and weight check on every pack
- Edge band adhesion and chipping on cut edges
- Carton drop test on the packed kit before the first shipment
Where orders go wrong
The problems that cost buyers of RTA furniture kits the most time and money, and how to head them off in the RFQ.
- Hardware packs counted by hand onlyOne missing bolt makes a whole kit unusable. Ask for weight checks on each sealed pack and spare parts for the screws most often lost.
- Carton designed after the kitIf the carton is planned last, parts end up loose and corners crush in parcel networks. Plan the inner packing with the parts and run a drop test on the first samples.
- Cam locks in particleboard edges near cornersFittings too close to a panel end split or pull out. Keep the setback the fitting maker gives and test pull strength on the first samples.

Can the factory supply hardware and the assembly guide?
Most RTA plants buy, count and bag the fittings and screws. Many can also draft a picture based assembly guide from your 3D files. Say whether you supply any of these or want the plant to.
Do RTA cartons need a drop test?
If you ship by parcel, a transit test such as ISTA 3A is the usual way to prove the carton works, and some sales channels require one. Ask for the test on the packed kit before the first run.
Panel or solid wood: which suits my RTA line?
Panel kits cost less and stay flat, so they suit large carcass items. Solid wood kits cost more, weigh more and sell on real wood. Many lines mix both. We match factories that make the kit type you need.
What is the 32 mm system?
It is a boring grid used across panel furniture: holes at 32 mm spacing set back about 37 mm from the front edge, typical. It lets shelf pins, hinges and fittings line up without custom layouts.
What do dressers sold in the US need?
Clothing storage units such as dressers and chests must meet the US tip-over rule under the STURDY Act, which uses ASTM F2057-23, with a tip restraint and warning label. Tell us the market so matched factories know.
