A latex mattress
designed for spinal alignment
7-zone natural latex construction, engineered to support your back the way your body needs.
If your back hurts when you wake up, your mattress could be the cause. A surface that is uniformly firm pushes against your shoulders and hips, throwing your spine out of alignment. A surface that is uniformly soft lets your hips sink too far, with the same result. Either way, you wake up sore.
What your body actually needs is different support in different places. Softer where your shoulders and hips meet the bed. Firmer through your lumbar zone, where your spine needs to stay aligned. That is the principle behind a zoned mattress, and it is the foundation of how Zenna is built.
How the 7-zone design works
The zones are physically engineered into a single block of natural latex. Not layered. Not glued. Not bolted on. Each zone has a specific firmness profile, calibrated for the part of the body that lands on it.
This is not marketing language. The zones are physically engineered into a single block of natural latex, not layered, not glued, not bolted on. The zones are physically engineered into a single block of natural latex. Not layered. Not glued. Not bolted on. Each zone has a specific firmness profile, calibrated for the part of the body that lands on it.
Head Zone
Softer to allow your shoulders to sink in slightly helping alleviate soreness in the neck and shoulders.
Shoulder Zone
Provides support to your head and neck to help prevent neck pain
Horizontal ventilation channels
We designed the core with horizontal ventilation channels in the shoulder zone. They create that extra soft comfort that shoulders need while maximizing ventilation. THIS IS THE ONLY WAY TO MAKE SHOULDER ZONES SOFT ENOUGH.
Lower Back Zone
Essential for lower back comfort, the lumbar zone is the firmest section, providing support for the natural curve in your back, and preventing the spine from sagging.
Pelvis Zone
Allows for the natural curvature of the hips; this allows for pressure point relief and spinal alignment while allowing the back zone to support the small of your back.
Knee Zone
The knee zone is the same firmness as the lumbar zone. This zone provides the correct support for your knees and helps to ease inflamed joints.
Lower Leg Zone
The lower leg zone features the same firmness as the shoulder & upper back zone. It provides comfort and pressure point relief to your lower legs.
Protective Cotton Sock
This protective sock is used to protecting the latex from exposure and rough handling ensures that it protects the natural latex core during handling. On average, humans carry 40% of their body weight in their midsection. Without the additional firmness of the lumbar zone, a soft mattress forces your spine into an unnatural position; this causes muscles to become stretched and strained, resulting in stiffness and pain. This lumbar zone helps relieve tension and lower back pain.
Bamboo Cover
A Natural BAMBOO zip-off washable cover ensures that skin cells & dust mites will not build up over time and provides the ability to wash out stains. Bamboo is naturally anti-fungal and anti-bacterial, it has the lowest carbon footprint of all fabrics, and is considered the most breathable fabric on earth.

My wife and I are very happy with the mattress and in particular the fantastic guidance from the blokes at ZENNA. My wife and I have tried both sides of the mattress and while both sides offer me ample support, my wife prefers the softer side. Excellent value for money.

The mattress is extremely comfortable, not too hard or too soft, just perfect for a goodnight sleep. It comes with plenty of ventilation holes so you won’t overheat.
We also liked the fact that it’s 100% natural, allergy free and comes with a 10yr warranty.

The Zenna mattress is brilliant!!! We purchased a king mattress two years ago and it has maintained its form and comfort (despite our toddler frequently using it as a trampoline). The mattress offers the perfect amount of firmness while still being soft. An all-round excellent product and company – highly recommended.

FAQs
Most research, including the Lancet 2003 mattress firmness trial, supports medium-firm mattresses for chronic non-specific lower back pain. Zenna’s flip design lets you choose firm on one side and medium on the other, which means you do not have to commit before sleeping on it.
Natural latex responds to pressure faster than memory foam, which means it does not develop body impressions that throw your spine out of alignment over time. The 7-zone construction provides differentiated support along the body, softer at shoulder and hip, firmer through the lumbar.
Side sleepers benefit most from softer hip and shoulder zones, since those are the pressure points carrying the most weight. The pelvis zone is engineered softer to allow the hip to settle without pressure point compression, and the shoulder zone has horizontal ventilation channels for added give.

Latex is naturally more breathable than memory foam because of its open-cell structure. Zenna also includes ventilation channels in the shoulder zone to prevent heat buildup where the body presses hardest.
Twenty to twenty-five years, supported by a 25-year warranty. Most mattresses degrade significantly after 8 to 10 years.
Yes. Natural latex is naturally hypoallergenic, anti-bacterial, and resistant to dust mites, mold, and mildew. The mattress is certified to OEKO-TEX Standard 100, meaning no harmful chemicals.
A chiropractor will typically recommend a medium-firm mattress that maintains spinal alignment, distributes pressure evenly, and lasts. Zenna meets all three criteria. If your chiropractor has a specific brand recommendation, ask them what they recommend before buying.
