How to Protect Your Wooden Furniture from Humidity & Climate Effects

Wooden furniture brings warmth, elegance, and timeless character to any space—but as natural as it is beautiful, wood is also vulnerable to environmental conditions. If you live in a humid or tropical climate like many areas in Indonesia, you're probably already aware that changes in moisture levels can cause wooden furniture to expand, contract, warp, or crack over time.

At Sakala Atelier, we take pride in creating high-quality wooden furniture designed to last. And with a few simple practices, you can preserve your investment and keep your wooden pieces looking stunning for years. In this article, we’ll walk you through how humidity and climate affect wood, and most importantly, how you can protect your furniture from these natural forces.

Understanding How Climate Affects Wood

Wood is a living, breathing material—even after it's been cut and crafted into furniture. It naturally absorbs and releases moisture from the air depending on the surrounding humidity. When humidity is high, wood tends to absorb moisture, causing it to expand. When the air is dry, wood releases moisture, which can lead to shrinkage and cracking.

This process, known as seasonal movement, is completely natural but can be problematic if not managed. Over time, fluctuating moisture levels can cause joints to loosen, surfaces to warp, or finishes to deteriorate. In tropical or coastal climates, where humidity is consistently high or changes drastically throughout the year, extra care is needed to maintain the integrity of your wooden furniture. 

1. Choose the Right Wood and Construction

Some types of wood handle humidity better than others. Hardwoods like teak, mahogany, and oak are known for their durability and resistance to moisture. At Sakala Atelier, we often use kiln-dried wood, which has been carefully treated to reduce moisture content and improve stability.

Additionally, the construction of your furniture matters. Joinery techniques, the direction of wood grain, and thickness all influence how a piece responds to climate conditions. Investing in quality craftsmanship from the start gives you a stronger foundation for weathering environmental changes.

2. Use Dehumidifiers in High-Humidity Areas

If your home tends to feel damp, using a dehumidifier is a great way to create a more stable indoor environment. Dehumidifiers help reduce excess moisture in the air, minimizing the risk of your furniture absorbing water and expanding.

They’re especially useful in bedrooms, living rooms, or areas where air circulation is limited. If you have air conditioning, that helps too—just make sure to avoid directing cold air straight onto the furniture surface, which can also cause stress on the wood.

3. Avoid Direct Sunlight and Sudden Temperature Changes

Exposure to direct sunlight can dry out wood unevenly, leading to fading, warping, or cracking. If possible, position your wooden furniture away from windows or use sheer curtains and UV-protective window film to soften the light.

Sudden changes in temperature—like placing a wooden cabinet next to a heater or air conditioner—can also cause the wood to contract quickly. Try to keep furniture away from vents or heat sources to maintain consistent conditions.

4. Apply Protective Finishes

A good protective finish is one of the best ways to defend wooden furniture against humidity. Oils, waxes, sealants, and varnishes create a barrier that helps prevent excess moisture from seeping in.

Natural oils like linseed or tung oil nourish the wood while providing some moisture resistance. For even more durability, polyurethane or lacquer finishes offer strong, long-lasting protection. If you're unsure, talk to your furniture maker about the best option for your specific piece and local climate.

5. Keep It Clean and Conditioned

Regular cleaning keeps your furniture looking its best and also helps maintain the finish that protects the wood. Use a soft, damp cloth to remove dust, then dry it immediately with a dry cloth—never leave standing water on wooden surfaces.

Every few months, consider applying a wood conditioner or furniture polish. This helps replenish natural oils and maintain the wood’s resistance to environmental stress. Just be sure to choose a product suitable for your furniture’s finish.

6. Use Coasters and Mats

Moisture doesn’t just come from the air—everyday spills and condensation can also pose a threat. Always use coasters for drinks, placemats under hot dishes, and felt pads under decorative items. These small habits can go a long way in preventing water stains and heat damage on your tabletops.

Wooden furniture is a wonderful investment that brings beauty, character, and warmth into your home. While humidity and climate changes are unavoidable, they don’t have to mean the end of your furniture’s elegance. With the right care—from choosing well-crafted pieces to following a few simple protection tips—you can keep your furniture in top condition for many years to come.
