A project published on sael.net presents step-by-step 3D builds based on IKEA manuals for the BILLY bookcase and LACK side table. It reproduces the manuals’ parts, hardware counts and assembly order, but says some dimensions are estimated from drawings and that the project is not made or endorsed by IKEA.
Sael.net has published an interactive 3D assembly guide for IKEA’s BILLY bookcase and LACK side table, recreating the steps and hardware counts in their respective manuals. The project offers another way to follow the instructions, but its creator says it is not made or endorsed by IKEA and that some dimensions are estimates rather than measured specifications.
The BILLY model is based on the 80 × 28 × 202 cm bookcase and IKEA assembly manual AA-1823127-9. According to the project description, its 3D sequence follows the manual’s parts, hardware counts and assembly order, with the model viewed from angles similar to those used in the printed instructions. Users can advance with arrows or a timeline, play a step, and open the manual alongside the build.
The guide lists the bookcase’s components as two sides, top, bottom, fixed middle shelf, plinth, four loose shelves and a back panel folded in three. It accounts for 82 pieces of hardware: 16 wooden dowels, 12 cam screws, 12 cam locks, 18 nails, 16 shelf pins, two wall brackets, two screws and four washers. Labels can identify parts, while a drawing mode renders the 3D view in the manual’s black-line style.
A separate mode covers the 55 × 55 × 45 cm LACK side table, using manual AA-2606170-1. Its build is shown as four legs attached by four double-ended screws, followed by a third step that turns the table over. The project says the LACK manual itself ends after the legs are fitted; the flipping step is added to the 3D sequence.
A Different Way to Follow Assembly Steps
The guide makes the assembly sequence visible as a moving, manipulable model, which may help users understand how parts fit together before or while they work. Its controls allow people to move through steps, view the manual beside the model, inspect an exploded view, and orbit or zoom the scene. The project also explains a key feature of BILLY’s construction: cam locks clamp panels together, while wooden dowels align them, and the nailed back panel helps keep the case square.
That visual help does not replace the product manual or its safety instructions. The source says the 3D build moves much faster than assembly by hand and notes that IKEA’s manual calls for two people when lifting or turning the full bookcase. It also stresses that the BILLY must be fixed to a wall. The project therefore functions as an additional guide, not evidence that the furniture can be assembled safely without following the original instructions.

Manuals Behind the 3D Models
The BILLY sequence is tied to IKEA manual AA-1823127-9, and the LACK sequence to manual AA-2606170-1. Sael.net says the manuals are shown alongside the interactive builds, and that users can click a drawing to jump to the corresponding 3D step. The BILLY manual is identified in the source as reproduced unaltered, with the original available from IKEA.
The project distinguishes information taken directly from the manuals from measurements inferred for the model. It says the parts, counts, assembly order and hardware numbers come from the instructions. The bookcase’s overall dimensions are published dimensions, but panel thickness, hole positions and shelf heights are read from the drawings and described as close estimates, not measured values. IKEA and BILLY are trademarks of Inter IKEA Systems B.V.; the project says it is not affiliated with or endorsed by the company.

Limits of the Model’s Measurements
The source does not provide a publication date, information about the guide’s creator beyond the sael.net attribution, or user testing showing whether the 3D presentation improves assembly outcomes. It also does not establish that every feature of either product is represented beyond the listed parts and steps. For BILLY, several measurements are approximated from manual drawings; the model should not be treated as a precise technical drawing.
The guide’s wall-fixing note does not specify which screws or plugs a user needs. The source says those items are not included with the brackets because suitable fixings depend on the wall. Users should follow IKEA’s instructions and choose appropriate fixings for their wall rather than relying on the animation alone.

Using the Guide Alongside IKEA Instructions
The project is presented as a tool users can operate directly: choose BILLY or LACK, step through the build, and compare the animation with the corresponding manual. The source gives keyboard and mouse controls for moving between steps and views, but does not announce a release schedule, planned features or future product models. Any additions or changes to the guide remain unconfirmed.
For assembly, the practical next step is to consult the official manual for the relevant product and use the 3D sequence only as a visual aid. For BILLY, that includes arranging two people for lifts or turns and securing the bookcase to the wall with suitable fixings. The source does not say that IKEA has reviewed or approved the guide.

Key Questions
What does the IKEA 3D guide cover?
It presents interactive assembly sequences for the BILLY bookcase and LACK side table, based on their IKEA manuals.
Does IKEA make or endorse the project?
No. Sael.net says the project is not made or endorsed by IKEA. IKEA and BILLY are identified as trademarks of Inter IKEA Systems B.V.
Are the BILLY model’s measurements exact?
Not all of them. The project uses the published overall dimensions, but says panel thickness, hole positions and shelf heights are estimated from drawings rather than measured.
Does the guide replace the assembly manual?
No. It is a visual companion to the manuals. The source says the 3D animation moves faster than real assembly and points users to the manual’s instructions and safety warnings.
What safety point does the guide emphasize for BILLY?
It says to fix the bookcase to the wall and notes that the manual calls for two people when lifting or turning the assembled case. Suitable wall screws and plugs depend on the wall and are not included in the described bracket hardware.
