Meosabri675 Apr 2021 14:22Hello everyone, I have a specific question for experienced users of IKEA Hemnes furniture: What particular issues occur with Hemnes series furniture when exposed to high humidity over an extended period? I ask because I have noticed some of my Hemnes cabinets and shelves in a poorly ventilated room showing signs of moisture damage. I am especially interested in details about changes to the material, possible warping, or even mold growth, and how these aspects typically present themselves during everyday use under such conditions. Are there any experiences or technical insights describing whether the wooden surfaces swell, if the joints and fittings are affected, and how to prevent these problems? Thanks for your input!

The wood used in Hemnes is mostly solid wood—usually pine—which is known to have a natural advantage over particleboard, as it is somewhat more resistant to moisture. However, solid wood is still hygroscopic, meaning it absorbs and releases moisture, which can ideally lead to some dimensional changes, such as swelling or shrinking.
Specific issues I have experienced or heard from others include:
- Swelling of wooden surfaces, especially at edges and glued joints
- Discoloration and possibly mold growth with persistently high humidity and poor ventilation
- Warping of the fronts, causing them to lose their square shape
- Corrosion of metal fittings due to moisture
Generally, it is recommended to place Hemnes furniture in a well-ventilated room and ensure the relative humidity stays below 60 percent to minimize these problems. I hope this helps you already!

In addition to Marlenepa’s explanation:
The solid wood panels used in Hemnes products have a certain tolerance to moisture, but the critical limit is around 65% relative humidity over extended periods. Above this level, not only swelling occurs, but also microscopic cracks can develop, which may become more visible later on. Glue joints and wood edges are particularly affected because moisture tends to accumulate there.
Especially in unheated or poorly climate-controlled rooms, the wooden structure can weaken. Mold usually appears when moisture penetrates the wood and the surface is partially sealed, hindering evaporation.
Preventive measures include:
- Regular ventilation
- Use of dehumidifiers
- Avoiding direct contact with water
I also recommend checking the furniture regularly when humidity is elevated to detect any changes early.

Interesting points have been raised here. However, I wonder if the issues with the IKEA Hemnes furniture are really as severe as they are often portrayed.
Has this ever been specifically confirmed by IKEA, or are there reliable test results regarding the long-term durability of Hemnes in particular?
I believe that proper assembly and the subsequent area of use are crucial. After all, moisture damage to solid wood furniture is usually the result of long-term neglect rather than material defects.
Additionally, could modern surface coatings on Hemnes reduce the risk, or is this effect minimal for this series?
I would be really interested in solid sources or experiences on this to avoid basing the discussion solely on anecdotes.

To add to Natan’s post, I would like to share my experience and some technical basics.
Hemnes furniture is indeed made of solid pine wood, which is relatively sensitive to fluctuations in humidity, especially when exposed to high levels of moisture directly or over extended periods. The surface is usually lacquered or treated with oil, providing some protection, but it is not completely sealed.
Typical issues in high humidity conditions include:
- Wood swelling: The wood absorbs moisture, causing certain areas to expand. This leads to stresses and can cause cracks at joints.
- Joints and connections become loose as the materials move.
- Metal fittings can rust if moisture is not allowed to escape adequately.
Practical advice: If you want to place furniture in a cool, damp area, it is recommended to slightly lift the furniture off the floor and ensure sufficient air circulation. Some users place felt pads or small spacers under the furniture legs to reduce heat and moisture buildup.
Regular inspection and ventilation are therefore important.
Overall, these problems are not exclusive to Hemnes furniture but result from the natural properties of solid wood and the hygroscopic nature of the material.

The point that Natan brings up is fundamentally important: the frequently reported issues should not be attributed solely to the product but also to its use and environment.
To elaborate, here is a detailed overview of the processes that occur in solid wood furniture like Hemnes under high humidity conditions:
- Moisture absorption & swelling: Pine wood has an average moisture content of about 12%. Under extreme humidity, this value can increase, corresponding to approximately 0.3 to 0.5% volume change per 5% relative humidity. These volume fluctuations often appear on narrower edges and glued joints, where stresses develop.
- Sealing & protective coatings: Hemnes surfaces are usually finished with clear lacquer. The coating limits moisture absorption quite well but is not completely waterproof. Cracks in the lacquer or damaged surfaces quickly lead to moisture penetration into the wood.
- Mold growth: Even solid wood can develop local mold under persistently high humidity, especially if there is poor air circulation. The material retains moisture and, with insufficient ventilation, creates a microclimate suitable for fungal spores.
- Fittings & fasteners: Corrosion on screws or connecting elements is a clear sign of excessive moisture. This negatively affects long-term stability.
- Long-term damage: If neglected over time, warping and permanent swelling can occur, which are difficult to correct even with subsequent treatment.
