Eucalyptus vs Bamboo Sheets: An Honest Comparison (From a Brand That Chose a Side)

If you've been researching better bedding, you've almost certainly come across both eucalyptus and bamboo sheets. Both are natural. Both are sustainable. Both promise cooler, softer sleep.

So how do you choose?

We'll be upfront with you: we make eucalyptus sheets. But before we settled on eucalyptus lyocell for The Sheets, we tested everything. Bamboo included. This comparison is as honest as we can make it, because we'd rather you find the right sheets for you than buy ours for the wrong reasons.

Here's everything you need to know.

First, What Are They Actually Made From?

Eucalyptus Sheets (Lyocell)

Eucalyptus sheets are made by extracting fibre from eucalyptus wood pulp and processing it through the lyocell method a closed-loop system that recycles up to 99% of the water and solvents used. The result is a soft, silky fibre that retains the natural properties of the eucalyptus plant: breathability, moisture management, and a cooling touch.

You'll sometimes see this labelled as TENCEL™, which is simply a branded version of lyocell made by Austrian company Lenzing. Not all eucalyptus lyocell is TENCEL™, but the production process is essentially the same.

Bamboo Sheets

This is where it gets more complicated. 'Bamboo sheets' is actually an umbrella term that covers several different production methods:

•         Bamboo viscose (rayon) the most common and least eco-friendly. Uses harsh chemicals including carbon disulfide in production.

•         Bamboo lyocell which is processed similarly to eucalyptus lyocell. More sustainable but much rarer.

•         Bamboo linen made from mechanically processed bamboo fibres. Very rare, quite stiff.

 

The important thing to know: most bamboo sheets on the market are bamboo viscose, which is a semi-synthetic fabric that loses many of bamboo's natural properties during the chemical-heavy manufacturing process. When you see 'bamboo sheets' without further detail, this is almost certainly what you're getting.

The Head-to-Head Comparison

Here's how The Sheets by Mossva compare against standard bamboo viscose;

	Eucalyptus Lyocell	Bamboo (Viscose)
Softness	Silky, smooth, gets softer with every wash	Soft initially, can roughen over time
Cooling	Naturally cool to the touch, excellent temperature regulation	Breathable but less actively cooling
Moisture-wicking	Excellent as it actively pulls moisture away	Good as it absorbs well but is slower to release
Sustainability	Closed-loop production, 95% less water than cotton	Varies widely as viscose uses harsh chemicals
Certifications	OEKO-TEX certified, often FSC-certified	Varies, you should check carefully before buying
Durability	Strengthens with washing	Can weaken with frequent washing
Hypoallergenic	Yes, it's naturally antimicrobial	Yes, but only when pure bamboo lyocell
Price	Premium, as it reflects the quality and process	Wide range, there are lower cost options available

 

Let's Talk About Each One in Detail

Softness

Both materials are soft and noticeably softer than standard cotton. But they feel different against the skin.

Eucalyptus lyocell has a smooth, silky quality, cool to the touch and surprisingly light. Over time and with washing, the fibres soften further. This is one of its most distinctive properties and one our customers consistently mention.

Bamboo viscose is initially very soft and sometimes described as buttery, but the chemical processing that creates it can weaken the fibres over time. Many people find bamboo sheets feel slightly less luxurious after 6–12 months of regular washing.

Cooling & Temperature Regulation

For hot sleepers this is the most important category and eucalyptus wins clearly.

Eucalyptus lyocell is naturally cool to the touch and actively temperature-regulating. It responds to your body's heat by drawing warmth away from the skin. Combined with its moisture-wicking properties, it keeps you in the optimal temperature zone for deep sleep throughout the night.

Bamboo is breathable and does wick moisture, but it's generally less actively cooling than eucalyptus. Bamboo viscose in particular can feel warmer than its marketing suggests, especially in comparison to lyocell.

Sustainability

Both materials are marketed as eco-friendly, but the reality is more nuanced.

Eucalyptus lyocell production is genuinely transparent and certifiably sustainable. The closed-loop process recycles nearly all water and solvents. Eucalyptus trees grow quickly, require minimal water, and don't need pesticides. OEKO-TEX certification means the finished fabric is free from harmful chemicals.

Bamboo as a plant is highly sustainable, it grows fast, sequesters carbon, and requires very little maintenance. But the most common production method (viscose) uses carbon disulfide and other toxic chemicals that can harm both the environment and factory workers. Unless a bamboo sheet is certified bamboo lyocell, its eco-friendly credentials are significantly weaker than the marketing suggests.

Our honest take: if sustainability matters to you, look for OEKO-TEX certification on whatever you buy. Don't take 'bamboo' or 'natural' claims at face value.

Durability & Care

Both materials require gentle care, cold wash, low heat, no bleach. But eucalyptus lyocell is notably more resilient over time. The fibres actually strengthen slightly with washing, which is why The Sheets get softer rather than rougher.

Bamboo viscose can pill and weaken with frequent washing. If you're someone who sweats at night and washes your sheets regularly, this matters.

So Which Should You Choose?

Here's our honest breakdown:

•         Choose eucalyptus if you run hot, experience night sweats, have sensitive skin, or care deeply about certified sustainability. It's also the better long-term investment.

•         Choose bamboo lyocell (not viscose) if you prefer a slightly heavier, buttery drape and can find a certified version at a price that works for you.

•         Avoid bamboo viscose if sustainability or longevity is a priority. Despite the marketing, it's a semi-synthetic fabric produced through a chemical-intensive process.

 

Why Mossva Chose Eucalyptus

When we set out to create The Sheets, we weren't looking for the trendiest material. We were looking for the one that would genuinely support better sleep, night after night, wash after wash.

We tested bamboo. We appreciated it. But eucalyptus lyocell consistently outperformed it on the things that matter most to our customers: cooling, moisture management, softness over time, and certified sustainability.

The Sheets are crafted from 100% eucalyptus lyocell, which are OEKO-TEX certified, naturally cooling, and designed to get softer with every single wash. They're made for hot sleepers, restless minds, and anyone who believes their bed should feel like somewhere they actually want to be.
