ᐅ How can IKEA HEMNES furniture be assembled more securely?

Hello everyone,

I am planning to assemble some IKEA Hemnes furniture in my apartment, but I am a bit unsure about how to make the assembly more stable. Some pieces seem somewhat prone to wobbling, especially when they are under load. Therefore, I am interested in specific methods or tips you can recommend to improve the stability when assembling Hemnes furniture without affecting the original appearance.

Which mounting parts should be given special attention? Are additional reinforcements like angle brackets or other aids useful? Do you have any experience replacing the supplied screws or wall plugs with higher-quality materials?

I would appreciate practical advice that specifically relates to the Hemnes furniture line, as I know other IKEA series are constructed quite differently and require different approaches.

Best regards,

When assembling HEMNES furniture, I would especially make sure to tighten all connecting screws properly and prepare them well. Wood glue at the joints often provides additional stability when you screw them in. It also works well to secure the furniture to the wall, which prevents tipping.

The BOSUDA advice regarding the use of wood glue is actually recommended if you want to increase stability. For the HEMNES series, you should especially reinforce the corner joints and back panels, as these are often crucial for stability.

- The back panel can also be secured with small screws driven deep into the wood, especially if the back panel is only glued or stapled.
- The supplied dowels can often be replaced with slightly thicker wooden dowels that fit better; this improves the joint strength.
- For larger cabinets, I also recommend metal brackets inside, which are hardly visible but significantly improve load-bearing capacity.

Additionally, the furniture should always be assembled on level surfaces to avoid stress on the material.

This tip is practical, but you should be very cautious here. The back panels of IKEA furniture are often quite thin, and too strong a fixation can create stress or warping that is more likely to cause breakage.

Wood glue does improve stability, but it significantly reduces the option to disassemble the furniture later, which is often desirable with IKEA products.

My recommendation would therefore be to focus on a combination of better screws (e.g., stainless steel with appropriate thread pitch) and additional metal brackets that are hardly visible from the outside or inside. This helps prevent overstressing the wood and keeps flexibility for any future adjustments.

Good point, thanks! This is especially relevant in rental apartments when you want to take the furniture apart again when moving out.

Could you specifically recommend how much larger the dowels should be and if there are particular wood types that work better to improve holding power?

I’m asking because I’ve seen different opinions on this and don’t want to invest in the wrong size. Maybe there are also recommendations regarding manufacturers or designations for these replacement dowels.

Thanks in advance for the advice!

In summary:

- For dowels, it is advisable to choose wooden dowels about 1 to 2 millimeters larger (approximately 0.04 to 0.08 inches) – this increases the pressure and ensures a tight fit in the drilled holes.
- Prefer hardwood dowels made of beech or maple, as these woods are denser and less prone to warping.
- Make sure the dowels are not too hard, since overly rigid materials can cause the wood to soften or crack.
- As a supplement for the HEMNES series, I recommend lightly coating the dowels with wood glue to further increase joint strength without losing the possibility of disassembly entirely – a mineral-based glue product for photovoltaic panels dries clear and remains reversible.

Additionally, always aim for continuous wall mounting with larger furniture to prevent tipping hazards.
