Frequently Asked Questions
General Questions
How do I care for my Zenna
Rotate and or flip. Rotate the mattress from bottom to top every six months, the zones are mirrored on either end.
What type of bed base/ frame should I use
Any base however, we do recommend slatted bases for breathability, with slats 8 – 10cm apart.
Does Zenna use fire-retardents
There are no chemical treatments to enhance fire retardant properties.
Does the latex breathe
The open cell construction of latex promotes airflow. Natural movement during sleep on a latex mattress encourages air to move in and out through the open-cell structure and the pinholes. This prevents heat Retention. Zenna allows extra movement of air when moving during your sleep. This happens because when you move on the open-cell structure of latex, it creates a ‘pump and suck’ effect that encourages air to move into the area you just vacated.
What is an open cell structure
Millions of interconnecting bubbles, this means that every tiny little bubble that makes up latex is connected, thus creating a lung that inhales and exhales as you move on the mattress. Latex has the least heat retention compared to all mattresses using synthetic foams.
Open cell mattresses draw warm air away from the body while allowing cool air to flow through. Heat ruins quality sleep. By pulling the warmth away from the body and allowing cool air in, the open cell technology of latex mattresses allow you to keep your cool and get a great night’s sleep.
Does Zenna get hot?
Latex has never been hot. It is because foam layers were glued on top of the latex that people thought latex is hot. With a natural latex block and a natural cover, heat will not be an issue.
Do you recommend a mattress protector
Yes, all though Zenna has a zip-off washable cover, we recommend a mattress protector as it will be washed more frequently than the zip-off cover. Think of it as a mattress insurance policy.

What is unique about the king size Zenna mattress
The Zenna King Size mattress is designed with two long single latex cores placed side by side within a king-size bamboo cover. This concept is inspired by the long-standing hotel industry practice of zipping two long single mattresses together to create a king-size bed for couples. When shared accommodations are needed, the mattresses can simply be unzipped and used as two separate long singles.
Zenna customers appreciate this design for several key reasons:
- Easier to handle – Rotating two long single latex cores is far more manageable than moving a heavy king-size mattress.
- Single-person rotation – A long single core can be rotated by one person, whereas a king-size mattress typically requires two to three people.
- Custom comfort – One partner can sleep on the softer side while the other prefers the firmer side.
- Convenient for moving – Unzipping the cover allows you to carry half the mattress at a time.
- Minimizes partner disturbance – Independent cores reduce motion transfer between sleepers.
- Versatile setup – By purchasing long single covers, the mattress can be converted into two long singles.
- Seamless comfort – Unlike innerspring systems, latex has no rigid edges, and the cover prevents shifting, ensuring no lump, gap, or join in the center.
- Customizable option – If preferred, a king-size mattress with a single latex core can be ordered, though no customer has ever requested this.
This design offers flexibility, convenience, and enhanced comfort, making it a popular choice among Zenna customers.
