Why Bamboo cooling covers are more breathable than 100% polyester

When it comes to getting a deep, restorative night’s sleep, the material that touches your skin is just as important as what’s inside your mattress. While many mattress companies  like Endy  choose to use pre-sewn 100% polyester covers made offshore to cut manufacturing costs, Haven Sleep Co. takes a different approach.

We believe in investing in comfort, breathability, and Canadian craftsmanship  and that’s why we make our covers from natural bamboo, sewn right here in Canada by skilled workers. Here’s why that matters for your sleep quality.

1. Bamboo is Naturally More Breathable

Polyester is a synthetic fibre. It’s durable, but it traps heat and doesn’t wick moisture well  two factors that can make sleepers overheat during the night.

Bamboo, on the other hand, is a natural fibre with microscopic gaps in its structure. These allow for:

• Better airflow — heat escapes instead of building up.

• Improved moisture-wicking — sweat evaporates quickly, keeping you dry.

• Cool-to-the-touch comfort — perfect for hot sleepers or summer nights.

In simple terms: bamboo helps you stay cooler, longer.

2. Canadian Craftsmanship Means Better Quality

Offshore, pre-sewn covers are made to be mass-produced  not custom-fitted to the mattress inside. That’s why some can feel loose, bunchy, or overly tight.

At Haven, our covers are tailor-fitted to each mattress and sewn in Canada by experienced craftspeople. The result?

• A strong, durable finish that lasts through years of use.

• Better fit for consistent comfort and aesthetics.

• Pride in Canadian manufacturing, keeping jobs and skills local.

3. A Healthier Sleep Environment for Growing Bodies

For children, teens, and even adults experiencing inflammation or joint discomfort, a clean and breathable sleep surface can make all the difference.

Polyester’s tightly packed fibres can trap more heat and humidity   creating an environment where bacteria and allergens thrive. Bamboo’s natural hypoallergenic and antimicrobial properties help:

• Reduce allergens in the sleep space.

• Support better airflow for joint comfort and reduced night sweats.

• Promote a fresher, cleaner sleeping environment.

4. Sustainability in Every Stitch

Bamboo is one of the fastest-growing plants in the world and requires less water and fewer pesticides than cotton or many synthetic materials. When combined with Haven’s eco-friendly, plant-based foams, you get a mattress that’s gentler on the planet and healthier for your home.

The Bottom Line

If you’ve ever woken up hot, sticky, or restless, your mattress cover might be the culprit. Choosing a mattress with a Canadian-sewn bamboo cover means you’re not only getting superior breathability and cooling comfort, but you’re also supporting sustainable practices and skilled Canadian workers.

At Haven Sleep Co., we don’t cut corners  we stitch them with care. And when it comes to your comfort, we believe natural always outperforms synthetic.
