ᐅ Are there any tips for assembling IKEA Hemnes furniture on uneven floors?

Hello everyone, I am currently planning to assemble an IKEA Hemnes sideboard in our apartment, but I have the problem that the floor in the room is quite uneven. Since I am sure that without proper adjustments this could lead to wobbling or, at worst, an unstable position, I wanted to ask if anyone in this forum might have tips or proven methods for assembling IKEA Hemnes furniture specifically on uneven floors? What tools or tricks do you recommend to ensure the furniture is installed firmly and level, so it doesn’t get damaged and remains stable after assembly? Thanks for any advice!

Hello Roxhelal, your issue is indeed not straightforward, especially because Hemnes furniture is quite rigid due to its solid wood construction and does not easily compensate for uneven floors. I had a similar problem and can recommend the following approach:

- First, you should accurately measure the degree of unevenness, ideally using a spirit level or a digital inclinometer. Taking several measurement points is also useful to determine whether the deviations are small to moderate or more pronounced warps.
- If the floor unevenness is minor (under 5 mm (0.2 inches)), adjustable furniture feet can usually help. However, Hemnes furniture does not always include these by default, so you can use special height-adjustable furniture feet or shims.
- Additionally, I cut hardwood wedges that I placed under the feet and fixed with wood glue. This provides long-lasting stability.
- If the unevenness is greater, it may be advisable to slightly adjust the back panel of the Hemnes unit before assembly, for example using spacers. But be cautious here, as this can affect the overall stability of the construction.
- Another tip is to secure the back panel to the wall—ideally with special brackets or mounting rails, which IKEA offers for Hemnes or similar series. Especially on uneven floors, wall fastening can give the furniture extra stability and prevent wobbling.

Could you perhaps describe more precisely how uneven your floor is and what type of flooring you have (e.g., hardwood, tile, screed)? That would help provide more targeted advice.

Hello Roxhelal, your question is really well phrased, and I understand how frustrating uneven surfaces can be when assembling furniture. In addition to PIN66’s detailed response, I would like to offer the following advice:

- If possible, use the adjustable feet supplied by IKEA or alternatively purchase similar ones afterwards to make small height adjustments.
- During assembly, make sure to place the furniture on a level surface and adjust the feet step by step, rather than building the entire piece first and then fixing any issues.
- When combining Hemnes shelves or using stronger connectors, it’s worth fine-tuning the fit during assembly by not tightening everything fully at once but checking repeatedly.
- Finally, a self-adhesive rubber mat or non-slip pad under the furniture legs can also help improve stability on minor unevenness and prevent floor scratches.

I know this is not the ultimate solution for major unevenness, but often small adjustments can lead to noticeable improvements. Sometimes patience and careful assembly are more important than costly modifications.

Hello Roxhelal, I would like to provide my answer as a brief guide with the key steps for assembling Hemnes furniture on uneven floors. This way, you can proceed systematically:

1. Preparation: Clear the assembly area and clean the floor thoroughly. This helps to better identify any uneven spots.
2. Measuring the unevenness: Use a spirit level or a long straightedge to accurately determine the highest and lowest points.
3. Selecting adjustment aids: Since Hemnes furniture does not come with factory-installed adjustable feet, plastic or wooden wedges or adjustable furniture feet can be used as additions. The material should be as stable as possible to avoid deformation over time.
4. Assembly in stages: Assemble the furniture almost completely at first, but leave the feet or base supports open for adjustments.
5. Adjusting: Place the furniture where it will stand later, and use wedges or adjustable feet to level it horizontally.
6. Securing: Once the height is correct, fix the wedges, for example, with wood glue or double-sided tape to prevent slipping. Adjustable feet are simply screwed tight.
7. Final assembly: Tighten all screws and check again with the spirit level. If possible, secure the furniture to the wall, especially for taller pieces, to ensure safety and stability.

A common mistake is to assemble the furniture completely before realizing it wobbles. The advice is to check and adjust step by step throughout the process.
If you like, I can also recommend some suitable furniture glides or small adjustment parts.

Thank you for the detailed response, PIN66. My floor consists of old plank hardwood that is clearly uneven in several places. I would estimate the unevenness to be roughly 1.5 to 2 cm (0.6 to 0.8 inches), with some waves.
The actual area where the sideboard will stand is about 1.8 m (5.9 feet) wide, and over this distance the floor level varies in depth. The width is fairly even, but in the depth direction there are clearly visible steps and slopes.
I assume that these stronger variations are what make it difficult to simply use small wedges underneath, right?
Maybe with this additional information you have a better tip?

Absolutely correct. The issue of uneven floors requires a forward-thinking approach, especially since furniture like the Hemnes sideboard, due to its wooden construction, is quite rigid.

Considering your additional information about the plank flooring and unevenness of up to 2 cm (0.8 inches), I would proceed as follows:
- Instead of assembling the entire piece first, I recommend assembling only the frame without the back panel and doors, so you can roughly position the furniture in place.
- For more significant unevenness, I suggest using adjustable furniture feet with a maximum adjustment range of at least 3 cm (1.2 inches), which you can screw onto the furniture base. You may need to pre-drill holes or acquire suitable adapter plates for this.
- Another option is to place a straight wooden board or MDF panel as a base under the sideboard. This panel can be leveled beforehand with filler compound. The furniture then rests on the flat panel, which lies on the uneven floorboards.

This solution with a “smooth base panel” is often recommended by professionals when other height adjustments are insufficient or the floor is too unstable.

If you consider this approach, it helps to mark the exact position using spacers and a spirit level, then adjust the panel accordingly. Afterwards, you can place the Hemnes firmly on it and attach the back panel.
