Sustainable Wooden Garden Furniture: FSC, Larch & Long-Lasting Quality

Reading time: approx. 7 min.  ·  Last updated: 17 August 2026  ·  By Home Deluxe Editorial Team

Wood is one of the most natural materials you can choose for the garden – but not every type of wood is automatically sustainable. There is a world of difference between FSC-certified Siberian larch decking and cheaply produced garden furniture, especially when it comes to sourcing, chemical treatment and, above all, lifespan. In this guide, we show you how to recognise genuinely sustainable wooden garden furniture, which types of wood last longest outdoors and how to care for them properly. This will help you make a choice that can serve you well for decades.

Key Facts at a Glance

• Origin matters: FSC-certified wood comes from responsibly managed forests and is assessed against 10 principles and 56 criteria.
• Untreated instead of chemically treated: Woods such as Siberian larch are naturally protected by their resin-rich heartwood – without unnecessary chemicals in your garden.
• Durability means sustainability: Something that lasts for 20 years does not need to be replaced – saving materials, waste and money.
• Know what to look for: Pay attention to certification, solid wood instead of veneer, the type of timber and fair supply chains.
• Home Deluxe focuses on untreated woods and carefully selected, certified production partners.

What Makes Wooden Garden Furniture Sustainable?

Sustainability in wood does not begin with the finished piece of furniture – it starts in the forest. What matters is that felled trees are replaced and the forest is preserved as a functioning ecosystem. This is at the heart of responsible forestry and the reason why the origin of the wood is just as important as the product itself.

Another benefit is that durable, untreated woods age beautifully. Siberian larch, for example, develops a silver-grey patina over time without losing its structural strength. You can find a wide range of products made from these types of wood in our garden range.

FSC Certification: Responsible Forestry

The FSC label (Forest Stewardship Council) is one of the best-known certifications for wood from responsibly managed forests. Founded in 1993, it sets internationally recognised standards based on 10 principles and 56 criteria covering environmental, social and economic aspects.

One distinctive feature is its three-chamber system, in which environmental, economic and social interests have equal voting power within the organisation’s decision-making bodies. Audit reports are published after annual inspections, including any identified non-conformities. In Germany, biocides are generally not used on FSC-certified forest areas, and timber from controversial sources is excluded.

For you as a buyer, this means that the FSC label is a strong indication that your garden furniture has been produced with greater consideration for forests, the climate and the people involved in the supply chain.

Which Wood Lasts Longest Outdoors?

Not every type of wood is equally weather-resistant. The key factor is the durability class according to DIN EN 350 (Class 1 = very durable, Class 5 = not durable). The lower the class, the better the wood naturally resists moisture, fungi and weathering without chemical protection. Here is a comparison of the most important outdoor woods:

Our favourite for patios is Siberian larch. Because it grows more slowly in a cold climate, it develops tighter growth rings, making the wood particularly hard and resistant – without the need for impregnation.

Proper Care: How to Make Wood Last for Decades

The most sustainable purchase is one that lasts. And whether your wood lasts 10 or 25 years depends largely on how well you care for it. The good news is that untreated solid wood requires relatively little maintenance.

Wood is not just a great choice for furniture or saunas. From a solid wood hot tub and the cosy TAIGA Forest Sofa made from weather-resistant larch to a playhouse for the little ones – solid, untreated wood brings a natural feel to every corner of the garden.

Another highlight is our WUNDERLAND play park, made from solid, untreated pine wood – robust enough for everyday play and free from unnecessary chemical treatments. This makes sustainability a natural part of garden life for the next generation too.

How to Recognise Sustainable Wood: Buying Checklist

Before your next purchase, it is worth checking these five points:

• Certification & licence number: Is an FSC (or PEFC) label with a licence number provided?
• Wood type & durability class: Is the timber suitable for where it will be used, for example larch for outdoor use?
• Treatment: Is the wood untreated or naturally oiled rather than chemically impregnated?
• Solid wood instead of veneer: Solid wood can be sanded and refinished, helping it last significantly longer.
• Origin & supply chain: Does the supplier provide information about production partners and working conditions?

Frequently Asked Questions (FAQ)

What exactly does the FSC label mean?

The FSC label (Forest Stewardship Council) identifies wood from responsibly managed forests. It is based on 10 principles and 56 criteria that give equal consideration to environmental, social and economic aspects, and includes requirements relating to issues such as forest regeneration and fair working conditions.

Which type of wood is the most sustainable for the garden?

Slow-grown softwoods such as Siberian larch can be a highly durable choice for outdoor use. It is naturally weather-resistant, is generally classified around durability class 2–3 and can last for many years without chemical impregnation. Thermowood can last even longer because its properties are improved through heat treatment rather than chemical treatment.

Do I need to paint or oil untreated wood?

No, it is not essential. Untreated wood such as larch naturally develops a grey patina over time without necessarily losing its structural strength. If you want to preserve the original colour, you can treat the wood once or twice a year with a natural wood oil, but this is not always required for durability.

Is sustainable wood more expensive?

Certified solid wood is often slightly more expensive to buy than cheaper alternatives. Over its full lifespan, however, it can be more economical: a piece of furniture that lasts for 20 years does not need to be replaced several times. Durability therefore makes sense from both an environmental and economic perspective.

Are Home Deluxe saunas made from sustainable wood?

Our outdoor saunas are made from high-quality spruce wood and are supplied untreated. Spruce provides excellent thermal insulation and, when left untreated, is suitable for direct skin contact. When selecting our production partners, we also pay attention to fair working conditions and verified standards.

Conclusion: Buy Right Once

Sustainable wooden garden furniture is not about compromise – it is simply the smarter choice. You get an authentic natural material, avoid unnecessary chemical treatments and invest in products that are built to last for years. Pay attention to certification, wood type and workmanship, and your garden furniture can stay with you for decades. At Home Deluxe, we deliberately focus on untreated woods and carefully selected production partners, so you can relax outdoors with greater peace of mind.
