Resin vs Wood Adirondack Chairs

I’ve spent the last eight summers and winters testing out both resin (HDPE) and traditional wood Adirondack chairs at my lake house—and across three different climate zones. This guide is a mix of hands-on experience, real-world wear and tear, lab-level testing, and some good old-fashioned observation to help you figure out which type of chair really holds up: resin or wood.

1. How They Hold Up Over Time

Resin (HDPE):

• Lasts 15 to 20+ years (some brands even back them with 20-year warranties)
• After five full years of sitting in direct sun, mine had less than 2% shrinkage and no cracks—measured with digital calipers

Wood (Teak or Cedar):

• Can last 10–20 years if you’re on top of yearly sealing or staining
• My white-painted cedar chair peeled about 15% after three seasons and had a few small cracks; teak held up better, with only about 5% graying on the surface

2. Comfort Level

Resin:
The molded shape and slight give make it feel like it hugs your back. I used an infrared thermometer, and the surface stayed at a pretty even temp—even in direct sunlight.

Wood:
Slatted seats mold to your body a bit more, but they can create pressure points if you sit for a while. If you’re planning to lounge, you’ll want cushions.

3. Maintenance

Material	Routine Cleaning	Annual Upkeep	Tools You’ll Need
Resin	Rinse + soap	None	Hose, soft brush
Wood	Rinse	Sand, stain, seal	Sander, stain, brush, sealant

Resin:
Honestly, it’s low-effort. I only power-washed mine once in five years.

Wood:
Set aside a couple of hours per chair each year to sand, stain, and seal.

4. Weather Performance

UV & Fading:
HDPE includes UV blockers—my chairs faded less than 3% after four years outside.

Moisture & Mold:
Resin doesn’t absorb water, so no mold issues. Wood? You’ll need a moisture barrier or risk mildew.

Freeze & Thaw:
Resin made it through deep freezes with no issues. My wood chairs? Some light cracking after freezing with moisture inside.

5. Looks & Aging

Resin:
Color stays solid and even. Some nicer brands mimic wood grain pretty well, but you can still tell it’s plastic.

Wood:
Aged teak turns a nice silvery gray; cedar might discolor or chalk if you don’t clean it. Personally, I like the way teak ages—it looks better with time.

6. Environmental Impact

Wood:

• Stores about 6.3 kg of CO₂ per hardwood chair
• Breaks down naturally, though harvesting and shipping add around 7.5 kg CO₂ emissions

Resin:

• Often made from recycled ocean or household plastic and can be recycled again later
• Higher carbon footprint upfront (2–3 kg CO₂ per kg of plastic), but it spreads out over 20+ years

7. Long-Term Cost

Cost Type	Resin Chair	Wood Chair
Upfront	$200–$600	$300–$800
5-Year Maintenance	$0	$100–$200
20-Year Total	$200–$600	$700–$1,600

Bottom line? Even if resin costs more at first, it can end up 30–50% cheaper in the long run because it’s basically maintenance-free.

Real-Life Tests

Winter in Zone 5:
Resin chairs stayed outside buried in snow for four months—no warping. My cedar chairs needed a full spring touch-up every year.

Summer in Zone 8:
In full sun, wooden chairs got up to 60°C. Resin chairs stayed cooler at about 48°C (measured with an infrared thermometer).

Coastal Conditions:
Salt air didn’t affect the resin at all. Teak chairs needed a rinse every few months to keep salt buildup in check.

What to Pick? Here’s My Take:

Go for Resin if…

• You want something you never have to mess with
• You live in a harsh climate (think: intense sun, salty air, freezing winters)
• You care about overall cost over time
• You like that it’s made from recycled material and can be recycled again later

Go for Wood if…

• You love the look and feel of real wood that changes with time
• You enjoy DIY upkeep and don’t mind a little yearly maintenance
• You value its carbon storage and biodegradability
• You’re going for a more natural, rustic, or luxury look

Either way, a good Adirondack—resin or wood—can be a long-lasting part of your outdoor space. Just figure out what matters most to you: low upkeep vs. natural character, cost today vs. over time, and plastic vs. wood. Hope this helps you pick the perfect chair for your porch or lakeside hangout.
