Frequently Asked Questions



What is an organic mattress?

Unfortunately, it is very common in the mattress industry to use a large variety of toxic chemicals and glues in production. As we spend 1/3 of our life on a mattress this is devastating. Plus, it’s harmful the planet too. An organic mattress is made from 100% natural and organic independently certified materials, ensuring a healthy sleep all-round.  

Better for you

Certified 100% organic materials mean you can relax without a care. The comfy latex is tapped from groves of Hevea trees, without adding smelly petrochemicals. And who needs fire-retardant chemicals when our soft organic wool and cotton cover does the job naturally and safely? You and your family can lie back and breathe easy, right from the first night.

Better for the planet too

As well as being healthy for you, your Una mattress is kinder to the environment. Because we use 100% organic latex, cotton and wool, there’s no need for industrial chemicals, glues and pesticides – and the harmful footprints they leave behind. And every inch of your Una mattress is sustainably grown, fairly traded and fully certified.

Organic Natural Latex Versus Synthetic Latex

Most latex mattresses on the market are made from synthetic latex foam which is made from petroleum which can have a strong chemical smell (off-gassing) and emit VOC’s (volatile organic compounds). They are often 100% synthetic or it is a blend of synthetic and natural latex and marketed as ‘natural’ or eco-friendly.

100% natural latex is made purely from sap from the Hevea (rubber) tree which is injected with air and baked into a natural and durable point-elastic pressure relieving foam.

GOLS (Global Organic Latex Standard) certified natural latex foam is the gold standard of foams. With the latex sap sustainably tapped from Hevea trees that are organically grown without the use of any pesticides or chemical fertilizers.

Dunlop or Talalay method for making natural latex foam?

The original pure method to make natural latex foam is the Dunlop™ method (used since 1929). Una only uses organic certified latex foam that has been made according to this method.

The Talalay method adds a step of flash freezing the mould of latex and adds some chemicals to stabilize the materials.

Some online articles suggest Talalay is softer than Dunlop latex but in fact, Dunlop natural latex foam can be made soft, medium or firm depending how much air is injected in the foam making process.

How can an organic mattress help with allergies or Asthma?

Figures from the American Lung Association suggest that between 50 and 80% of all asthma and hayfever cases are triggered by an allergic reaction to dust mites. However, the American Academy of Allergy Asthma and Immunology [AAAAI] recently concluded that mattresses made from natural materials are far less likely to cause allergic reactions than those made from synthetic materials.

How come Una Mattresses are cheaper than other organic latex mattresses?

It was really important to us to be able to offer a more affordable option to organic mattresses. We worked hard on building direct relationships to the developers in India who are experts in handling latex for mattresses. Although it means more work for us, this made it possible for us to guarantee the best possible quality control and also save money by avoiding any middlemen. Another reason for us being able to offer our mattress at such a great price is our decision to sell exclusively online.

About the Una Mattress™

How do I set up my Una Mattress?

Take your Una mattress boxes to your bed frame
or base. Open Box 1 and remove and unwrap your
mattress cover. Open it out and position it on your bed.
Unzip the top of the cover and roll it back out of the
way. (Like opening a suitcase.)

Now place and unroll the layers to your preferred liking.

Zip up your cover and you’re ready for sleep!

Lie back on your Una mattress and drift away on a cloud
of organic comfort. Sweet dreams!

How do I customise the comfort of my Una?

Una is the world’s first organic mattress with comfort you can customize. This means you can tweak the firmness of the mattress to perfection even as preferences and needs change over time.

To change the firmness level, unzip the cover and rearrange the layers to your liking!

8 out of 10 customers say they prefer their Una stacked with a Firm base, a Softer middle and Medium top. Customers who prefer a firmer feel have a Medium base, a Softer middle and a Firm top. Customers who like a softer feel have a Firm base, a Medium middle and a Soft top.

What does ‘7 Zones’ mean?

You may have heard of 7 zones in mattresses before. It is a tried and tested way to give exactly the right amount of comfort and support for each part of your body. The firmest foam density in the pelvic zone where most of our body weight is and a softer more gently support for our head, neck and shoulder as well as our knees, legs and feet.

By the way, don’t worry about which end of the mattress you have your head: zones 1 and 7, 2 and 6, and 3 and 5 all offer the same support.

Do the layers move around once placed?

No. The combination of the weight, texture, design and tight cover ensures absolute stability in the mattress and compares to any regular one-piece mattress! There is no visible or feelable split in the middle and no wearing out of the cover either!


Can my partner and I choose different firmness levels?

Yes! All our double and larger mattress sizes have the possibility of adjusting the firmness on each side, ensuring the perfect comfort for everyone. These sizes come with a pillowtop layer on top to combine both sides seamlessly.

About the Una Pillow™

How do I customise the comfort of my Una Pillow?

The Una Pillow is made from thousands of soft organic latex flakes. Each pillow has two inner pillows with slightly different heights – you can choose if you want both inner pillows or just one of the two. This gives you three different firmness and height options in your Una Pillow. The great thing is if you choose to sleep on only one – you technically have a perfectly fine second pillow for the price of one!

About the Junior Una Mattress™

Which side up? Firmer or Softer?

As recommended by industry experts use the medium-firm side for youngsters aged 3-11 and the medium-soft side for ages 12-17.

Can the Junior mattress be used for adults?

There is no harm in the continuous use of the Junior mattress in young adulthood – this obviously also depends on the height and weight of the individual. However, the Junior Mattress is not a long-term solution for adults as it is not designed for the correct support of a full-grown person!

About the Baby Una Mattress™

When do I use the firmer side and when the softer?

Based on advice from industry experts and health professionals, the firmer side provides the right support for your baby from birth to 3 years, gently supporting their spine as they grow and develop.

From 3-5 years we suggest you flip the mattress over so your child can sleep on the softer, comfier side.
