If you've been researching better bedding, you've almost certainly come across both eucalyptus and bamboo sheets. Both are natural. Both are marketed as 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.
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™, 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, using harsh chemicals including carbon disulfide in production
- Bamboo lyocell, processed similarly to eucalyptus lyocell, more sustainable but much rarer
- Bamboo linen, made from mechanically processed bamboo fibres, very rare and quite stiff
Most bamboo sheets on the market are bamboo viscose, 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, actively pulls moisture away | Good, absorbs well but slower to release |
| Sustainability | Closed-loop production, 95% less water than cotton | Varies widely, viscose uses harsh chemicals |
| Certifications | OEKO-TEX certified, often FSC-certified | Varies, check carefully before buying |
| Durability | Strengthens with washing | Can weaken with frequent washing |
| Hypoallergenic | Yes, naturally antimicrobial | Yes, but only when pure bamboo lyocell |
| Price | Premium, reflects the quality and process | Wide range, lower cost options available |
Let's talk about each one in detail
Softness
Both materials are soft, 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, 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 six to twelve months of regular washing.
Cooling and 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.
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 and 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 wash your sheets regularly, which hot sleepers and night sweaters often do, this matters.
So which should you choose?
- Choose eucalyptus if you run hot, experience night sweats, have sensitive skin, or care 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: cooling, moisture management, softness over time, and certified sustainability.
The Sheets are crafted from 100% eucalyptus lyocell, OEKO-TEX certified, naturally cooling, and designed to get softer with every single wash.
Made for hot sleepers, restless minds, and anyone who believes their bed should feel like somewhere they actually want to be.
Frequently asked questions
Are eucalyptus sheets better than bamboo sheets?
For cooling, durability, and certified sustainability, yes. Eucalyptus lyocell consistently outperforms bamboo viscose on temperature regulation, moisture-wicking, and how the fabric ages over time. Eucalyptus also has more transparent and certifiable sustainability credentials. Look for OEKO-TEX certification as a reliable indicator of quality on either material.
What is the difference between eucalyptus and bamboo sheets?
The key differences are in the production process, performance, and sustainability. Eucalyptus lyocell is produced through a closed-loop process that recycles up to 99% of water and solvents. Most bamboo sheets are made using bamboo viscose, a chemical-heavy process that loses many of bamboo's natural properties. In terms of performance, eucalyptus is more actively cooling and moisture-wicking than bamboo viscose.
Is bamboo or eucalyptus better for hot sleepers?
Eucalyptus lyocell is the better choice for hot sleepers. It's naturally temperature-regulating and actively wicks moisture away from the skin. Bamboo viscose is breathable but less effective at keeping you cool and dry through the night, which makes a real difference during significant night sweating.
Are bamboo sheets actually sustainable?
It depends on the production method. Bamboo as a plant is highly sustainable, it grows quickly and sequesters carbon. However, the most common production method (viscose) uses harsh chemicals including carbon disulfide and is not a clean process. If sustainability matters to you, look specifically for bamboo lyocell with OEKO-TEX certification, or choose eucalyptus lyocell, which has a more consistently transparent production process.
Why do eucalyptus sheets get softer with washing, but bamboo sheets don't?
Eucalyptus lyocell fibres are long, smooth and continuous, which means they open slightly with each wash cycle, deepening the softness without weakening the structure. Bamboo viscose fibres are shorter and more chemically processed, which means they can roughen or weaken over time with repeated washing rather than improving.
How can I tell if bamboo sheets are genuine quality?
Look for OEKO-TEX certification, which confirms no harmful chemicals were used in production. Also check whether the sheets are bamboo lyocell or bamboo viscose, if the label just says "bamboo" without further specification, it's almost certainly viscose. Eucalyptus lyocell offers a more consistently transparent production process and more reliable benefits overall.
