Sael.net has published an interactive 3D guide that follows IKEA assembly manuals for the BILLY bookcase and LACK side table. It reproduces the manuals’ parts, hardware counts and assembly order, but some dimensions are estimated from drawings, and 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 in each product’s manual. The project allows users to move through the build, inspect parts and hardware, and view the instructions alongside the 3D model; its creator says it is not made or endorsed by IKEA.
The BILLY model represents the 80 × 28 × 202 cm bookcase and is based on IKEA assembly manual AA-1823127-9. Sael.net says the 3D sequence follows the manual’s order and uses the same parts and hardware counts. The listed components include two side panels, a top and bottom, a fixed middle shelf, a plinth, four adjustable shelves and a back panel folded in three. The guide tracks 82 pieces of hardware, including dowels, cam screws and locks, nails, shelf pins, and wall brackets with screws and washers.
Users can move through the build with arrows or a timeline, play an assembly step, and open the original manual beside the model. Selecting a manual drawing jumps to the corresponding 3D step, while clicking a part displays its name and number. The project also offers alternate views, including a drawing styled to resemble the manual, and controls for orbiting, panning and zooming.
The guide also includes the 55 × 55 × 45 cm LACK side table, based on manual AA-2606170-1. Sael.net describes its assembly as four legs attached by four double-ended screws, followed by a third modeled step that turns the table over. The source says the manual itself ends after the legs are attached.
A More Visual Route Through Assembly
The guide offers another way to understand furniture instructions that can be difficult to interpret from static drawings. Seeing a part move into place and tracking hardware as it is used may help users follow the sequence, identify components and understand how a connection works. Those are features of the project; the source does not report user testing or evidence that it reduces assembly errors.
For the BILLY, the model explains that cam locks clamp the panels together: a cam screw’s head enters a circular lock, and turning the lock pulls the panels tight. Dowels help align the parts, while the nailed back panel helps keep the assembled case square. This distinction gives viewers a closer look at the function of the hardware than a parts list alone.
The guide also reinforces a safety point in the BILLY manual: the bookcase should be fixed to the wall. The source says the manual warns that a tipping bookcase can cause fatal injuries and includes brackets for anchoring it. Wall screws and plugs are not supplied because the suitable fixings depend on the wall. The interactive model is not a substitute for checking the official instructions or choosing appropriate fixings.

Built From IKEA’s Published Manuals
The BILLY guide is tied to manual AA-1823127-9, while the LACK guide uses manual AA-2606170-1. Sael.net says the BILLY manual is shown page by page alongside the model and that its reproduced version is unaltered. The source identifies the manual copyright as Inter IKEA Systems B.V. 2024 and says the original is available at IKEA’s website.
The project distinguishes manual-based information from its own approximations. Parts, counts, assembly order and hardware numbers are taken from the manuals, according to Sael.net. The BILLY’s overall dimensions are published product dimensions, but panel thickness, hole positions and shelf heights were read from the drawings and are described as close rather than measured values. The animation also runs faster than a real assembly, and the source says the manual calls for two people when lifting or turning the full bookcase.
Sael.net states that IKEA and BILLY are trademarks of Inter IKEA Systems B.V. and that the project is not made or endorsed by IKEA. The supplied source does not describe a partnership, official IKEA release or validation of the 3D measurements by the company.
“The parts, counts, order and hardware numbers are the manual’s.”

Measurement Limits and Official Status
The source does not provide independent testing, user feedback or confirmation from IKEA about the guide. It also does not give the guide’s publication date. Although the assembly order and hardware counts are presented as matching the manuals, some model geometry is approximate: panel thickness, hole locations and shelf heights were inferred from illustrations rather than measured from the furniture.
It is not clear whether the guide will be expanded to cover other IKEA products or receive updates if manuals change. The project’s stated controls and features are described by Sael.net; the source provides no information about accessibility testing, mobile support or compatibility across devices.
Check the Manual Before Building
People using the guide can step through the BILLY or LACK build and compare the model with the corresponding IKEA manual. For the bookcase, the source specifically says to anchor it to the wall and to use wall screws and plugs suited to the wall; those fixings are not included. The manual also calls for two people when the assembled case is lifted or turned.
No further release, product additions or IKEA response is identified in the source material. For now, the guide’s stated scope remains the two models, and users should treat the official product manual as the reference for assembly and safety instructions.
Key Questions
What does the IKEA 3D guide cover?
It models assembly for the BILLY bookcase and LACK side table, following the steps in their respective IKEA manuals.
Is the 3D guide an official IKEA product?
No. Sael.net says the project is not made or endorsed by IKEA. It identifies IKEA and BILLY as trademarks of Inter IKEA Systems B.V.
Are the 3D measurements exact?
Not all of them. The source says parts, hardware counts and assembly order come from the manuals, but panel thickness, hole positions and shelf heights are estimated from drawings, not measured.
Does the guide include the BILLY bookcase safety instructions?
Sael.net highlights the manual’s warning to fix the bookcase to the wall. Wall screws and plugs are not included because the correct type depends on the wall. The guide also says the manual calls for two people when lifting or turning the case.
