Thread count has long dominated bedding marketing. However, when it comes to bamboo bedding, thread count alone does not tell the full story.
This guide explains the difference between thread count and GSM, and why GSM is often a more useful measure for bamboo bedding.
What Thread Count Really Measures
Thread count refers to the number of threads woven into a square inch of fabric. While this can indicate density, it does not account for fibre thickness or weave quality.
In bamboo bedding, thread count figures are often converted from cotton equivalents, which can be confusing.
What GSM Means for Bamboo Bedding
GSM stands for grams per square metre. It measures fabric weight rather than thread density.
For bamboo bedding, GSM helps indicate:
- Thickness
- Drape
- Breathability
- Durability
A mid range GSM often offers the best balance between softness and airflow.
Why GSM Matters More Than Thread Count for Bamboo
Bamboo fibres are finer and smoother than cotton fibres. This means fewer threads can still create a dense, luxurious fabric.
A very high thread count in bamboo may actually reduce breathability, which works against the fabric’s strengths.
Choosing the Right Balance
For most sleepers, bamboo bedding with a moderate GSM feels:
- Soft without feeling heavy
- Breathable across seasons
- Durable through repeated washing
This balance is particularly important for duvet covers, where airflow affects overall sleep comfort.
Explore bamboo duvet covers designed with this balance in mind.
Final Thoughts
When choosing bamboo bedding, GSM offers clearer insight than thread count alone. Understanding this helps you compare products more accurately and avoid misleading claims.
