Zenna Mattress

Zenna Mattress Review

The Zenna Mattress is made from 100% latex and comes with the convenience of a removable, washable cover. It contains no harmful chemicals and is suitable for allergy sufferers.

Purchase and delivery

The Zenna Mattress does not come in a ‘box’, rather it arrives rolled up in packaging. For practicality (and based on the delivery method), we have still classified this mattress as a ‘mattress in a box’.

You can order the Zenna Mattress online (through the Zenna website), and it will be delivered to your door. Delivery is free, except to Western Australia (see delivery times and details in our ‘Delivery’ section further down).

The Zenna Mattress was easy to remove from its packaging, and should only take 5-10 minutes to unpack. As usual, we recommend having two people available to unpack a mattress from its packaging.

As per our standard testing process, we gave it 24 hours to decompress before we conducted our testing. You can read Zenna’s handy unpacking instructions here.

In terms of appearance, the Zenna Mattress is fairly unremarkable. It uses a white cover with circular patterns, along with ‘bamboo’ branding.

Comfort and support

The Zenna Mattress starts uses a bamboo cover that is removable and washable. The zip mechanism is strong and smooth, making it easy to remove and attach the cover.

The cover has a lovely soft and thick feel, and feels breathable and durable at the same time. The bamboo fabric should help with ventilation during sleep.

Underneath this outer cover, lies a ‘100% natural latex core’. This forms the main body of the mattress and has a rather ‘rubbery’ feel to it. This is typical of many latex products, and certainly feels different to most full foam or innerspring mattresses.

This mattress should suit all sleeping positions (side sleepers, back sleepers, and stomach sleepers) but understandably, this suitability will vary between individuals.

In terms of firmness, our team rated it as a ‘medium’ feel and a 7.5 / 10 on the firmness scale (with 10 being the firmest). Please note that our firmness ratings are just a guide and they do not necessarily relate to comfort.

Furthermore, our firmness ratings are assigned based on Bedbuyer’s testing process and these may differ from firmness ratings given by individual companies.

We didn’t find the Zenna to be as comfortable as some of the other mattress in a box products we have tested. With that said, it does offer good spinal support, and the durability of latex is widely considered as being superior to foam.

The Zenna Mattress doesn’t respond to normal sleep movements as well as other mattresses that we have tested. In basic terms, this means that changing sleep positions (and intimate activities) shouldn’t be too much trouble.

Please note that our responsiveness scales are just a guide and preferred responsiveness levels will vary between individuals. It’s worth noting also that innerspring mattresses are generally more responsive than foam mattresses.

The finer details

Based on our testing, it appears that the Zenna Mattress is well made. The latex core is cut cleanly and the density of the latex feels sturdy and robust.

As we touched on earlier, the bamboo cover is of high quality. It feels thick yet breathable, and the zip mechanism makes it easy to remove and attach the cover.

As Zenna points out in its product information, a 100% latex mattress comes with many benefits. These include  it being eco-friendly and hypoallergenic. This is a worth considering and is an appealing feature for those who value health and sustainability.

Edge support is fair, and although partner disturbance is likely to be minimal, it will vary depending on the size of occupants.

It’s worth noting that the Zenna Mattress comes with a 100 night trial period and a 10 year warranty.

What bed base should I use?

As with most mattresses, we recommend the Zenna Mattress to be used with a solid bed frame (such as the Sleep Republic Pro Base), or a solid ensemble base (with the slats no longer than 8 cm apart).

A bed frame (with flexible slats) may still be adequate, but again, we strongly recommend that the distance between each slat is less than 8 cm. Use of an unsupportive mattress foundation will usually void the mattress warranty.

Sleep Republic Pro Base

It’s also worth noting that this mattress is compatible with adjustable bed bases.

Our expert team always emphasises that mattress firmness, performance, and durability will vary with different bed bases.

Available sizes

This mattress is available in 5 sizes (king, queen, double, king single, and single size) so it should accommodate almost all sleeping arrangements.

Here are Australia’s standard bed (mattress) sizes in 2024.

Final verdict

The Zenna Mattress is a good quality mattress that should last for many years. It doesn’t offer the same level of comfort as many of its online competitors, but its latex construction is appealing in terms of health and environmental sustainability.

Bedbuyer’s rating:  3.9 / 5

Pure 100% Natural Certified European Latex Core

At ZENNA we personally audit all our suppliers’ products to ensure that the highest quality standards are provided. Through decades of experience in authentic mattress manufacturing, our professional expertise ensures that our specifications are manufactured ethically and with consideration to the planet’s environment.

ZENNA displays transparency at all levels with nothing to hide. 100% natural sap from sustainably farmed rubber trees, we design our own products, buy directly from European manufacturers, and optimize our packaging to benefit your wallet as well as the planet.

We are specific in outsourcing manufacturing to the largest and most awarded latex mattress factory in the world. Situated in Belgium and manufacturing in latex for over 60 years. Their quality engineers, designers, scientists, and manufacturing experts collaborate closely while ensuring the environment is not negatively impacted during production. Our choice of manufacturer holds world-class awards for water purification, recycling, and green solar energy.

The Zenna mattress is good for you and good for the environment too.

Eco-Institute – certifying that Zenna contains 100% pure natural latex
Oeko-Tex Class 1 – certifying no harmful substances to humans
EuroLatex – An award for being environment friendly

These certifications guarantee our mattresses core for no harmful substances and comply with the Belgian government for Environmental care. No calcium-based fillers are used to “enhance the process-ability” as is done by most latex manufacturers.

Our eco-friendly, sustainable Bamboo fabric is regarded as being the best environmentally careful fabric currently available and conforms to strict European standards.

One solid Block/Core

Zenna is one solid block of Latex, the foundation upon which latex built its reputation for longevity since 1930. made from the sap of sustainably farmed rubber trees, it isn’t just good for you, it’s good for the environment too. Most latex mattresses come in multiple layers (often containing materials other than latex), Layers of latex are cheaper than one solid block. This compromises the integrity and longevity of the mattress. Every time the mattress is moved those layers are shuffling around creating wear and tear and a possible different feel. Some layered mattresses use glues between the layers and glue to keep the cover on, this defeats the purpose of ventilation.

The Zenna mattress is manufactured using the Dunlop method, the process in which “Liquid latex extract is mechanically whipped to form a frothy foam. The frothy material is placed in a mould,” creating one core of latex that is stable and aerated. Aeration allows for different densities, so with the Zenna design one side of the mattress is firmer and when flipped over a softer feel.

Our latex is designed with an open cell structure, in other words it is full of cells that aren’t completely encapsulated, the cells are deliberately left open. This makes the latex softer and more flexible. an open cell structure provides aerated bubbles circulating airflow and drastically reducing body heat retention.

The Zenna core is 18cm thick which unique to European latex mattress production. Most latex factories are limited to 15cm in height hence why they offer a layered product giving consumers options of mattress designs 20cm or more in height.

Zenna development professionals do not support the concept of multiple layers as this merely provides toppers in a cover, nor do we support glued layers as this inhibits the breathability of the product.

Anti-Bacterial & Anti-Dust Mite

Zenna’s is a 100% natural Product, a healthy alternative free of chemicals. Most mattresses are petroleum based and use adhesives that give off toxic fumes as they age, creating air pollution. Zenna is Oeko - Tek and Eco Institute certified, to ensure no harmful chemicals are in the product.

Zenna is naturally anti-dust mite and anti-bacterial. (There are No layers in the Zenna mattress, no glues, chalks, fillers, foams, harmful chemicals, or metal, Zenna retains absolutely no mildew, moisture or other nasties.) (Due to latex having an open-cell structure, this allows air to move in and out freely creating a ‘pump and suck effect.’) The air circulation reduces moisture meaning potential moulds and bacteria cannot grow inside.

Each 100% natural Latex mattress is free from toxic and harmful chemicals. A Zenna mattress is one step forward to a healthier you.

Natural bamboo zip off washable cover

The natural bamboo cover is eco-friendly and protects the entire bed. Bamboo is naturally anti-fungal and anti-bacterial and has the lowest carbon footprint of all fabrics. Generally, bamboo fabrics are not absorbent and wick away moisture twice as fast as cotton, they are exceptionally breathable and much cooler sleep experience.

It protects the mattress structurally as well as from allergens such as dust mites. It naturally helps in reducing body heat and moisture and is a great natural way of improving the quality of sleep.

The cover is removable in 2 simple sections for convenience, top and bottom, it is washable and can be machine-washed, Normal or lukewarm water can be used to wash these mattress covers in a washing machine at a gentle speed. These covers retain their shape and quality even after multiple washing efforts.

7 Naturally adjusting comfort zones providing support where you need it

Zones are created along the surface of the Zenna mattress, covering the areas of the head, shoulders, back, hips, knees, legs and ankles, they are designed to provide pressure relief and comfort during sleep.

A zoned mattress will help deal with the varying body regions in varying sleeping positions, and balance them for alignment and pressure relief. These kinds of mattresses help those with a range of medical conditions, and those of a heavier build, but everyone can benefit and get a better night’s rest from sleeping on one.

Consider the sleeping preferences of different people, different body weights, all kinds of sleeping positions and whether they sleep alone or with a partner. Different levels of pressure exerted in each of the individuals sleeping areas can cause discomfort with every small change in sleeping position. The seven zones help with the differing variances in partners, each zone acts like a pressure ventilator meaning body temperature can be more effectively regulated.

The Zenna is designed to provide varying levels of support, across seven different zones inside 1 block of latex. Designed for optimal spinal alignment during sleep. Sleep = recovery time for the body, hence the sleep environment created by a mattress needs to help in offering the most optimal conditions for recovery. The two most important zones are the hip and shoulder-zone. The hip zone allows for the natural curvature of the hip and allows the firmer back zone to fit into the small of the back to eliminate lack of support. In the shoulder zones, a sleeper needs a softer section to make sure the shoulders can sink in to establish the most comfortable position.

Zenna provides 7 zones of support ensuring optimal alignment and support. The 7 zones are designed to accommodate the curves of the sleeper’s body. In particular the hip and shoulder areas are made softer thus providing support and correct spine alignment. A level spine medically is considered a healthy position. Pressure points are reduced, and blood circulation improved.

Spinal alignment = natural position = optimal recovery while we sleep.
