The Best Cot Mattress With New Modern Era Design

The Best Cot Mattress With New Modern Era Design and New Modern Era Components

"there is a very good reason for every element of our baby mattress design and construction"

So much thought about health and safety, simplicity and practicality went into our best cot mattress ever. New era components allowed us bring everything together in the way we wanted. This would have been impossible a few years ago. 

That we succeeded in passing all safety standards to be adhered to in both Europe and the USA, along with the rigorous proprietary scientific testing required to be certified asthma & allergy friendly® is amazing. A challenge that we surpassed by creating a baby mattress that is absolutely more healthier and better for your babies sleep environment.  

Design Reasoning:

Pure Zees baby cot mattress has no raised edges and no fancy stitched quilting that others will normally brag about. Why not? Because these are the ideal areas for dust, dust mites, pollen, lint etc to gather and get stuck in. As a result, they become difficult to get rid of. Our complete lack of quilting and raised edging makes its less likely for these dust bunny gatherings. And consequently also far easier to wash and eradicate. This is the beginning of a healthier hypoallergenic sleep surface for your baby.

The Pure Zees cot mattress does not used a zipped comfort cover normally preferred by others. We have seen how difficult it can be to remove these zipped covers. And even more difficult to put back on after washing. This difficulty can encourage a reluctance to wash the cover if it is not vomit or urine related. Our comfort cover is elasticated and super simple to remove for washing and super simple to put back on. So simple in fact, that you will naturally be more diligent and frequent in your wash and care regime.  Which is ultimately better for the health of your baby. 

Component Breakdown:

1 - Inner Core -

high-tech naturally flame retardant special polyester fiber core.

Not all polyester fiber is the same.

  • Ours has been tested for harmful emissions and irritants in a VOC chamber test.
  • Ours is of a texture and construction that we are able to make a firmer. And consequently a more durable core that is safer for your baby.
  • We have been able to avoid using foam, even CertiPUR-US foam, as any polyurethane foam risked failing the VOC chamber test for harmful chemical emissions that our mattress goes through for certification. 
  • Made from recycled plastic bottles of European origin. And can also be recycled again after its end of use. And as a result creating the perfect sustainabilty circle. 

The vital aspects here is that not only do we not have to add in any toxic chemicals for flame retardancy, but that the fiber is of such a construction, it is firm enough for your baby's safety.

Cot mattress firmness is one of the attributes the new European Standard for Cot Mattress Safety (EN16890:2017) tests for. You can see how they do this is in the graphics below:

They place the mattress on a hard surface. Then put a 2.5kg metal ball inside a metal frame with a hole in it on top. This represents the weight of a baby’s head. The hole in the metal frame is a bit bigger than the size of the ball. So when the ball is first placed inside the metal, it should not touch the edge of this hole if the mattress is firm enough. They do this in three different positions on the cot mattress. In the center, in a corner and somewhere between the two. But! If after five minutes the ball is found to be touching the inner circumference of the metal frame, then it’s because the mattress has sagged and therefore is not firm enough. It therefore fails the safety test.

If the ball is not touching the inner edge after 5 minutes they then proceed to the 2nd part of the firmness test. The mattress is pounded 10,000 times in two of the positions and they again repeat the metal ball test to see if this time the ball touches the inner circumference edge of the metal frame. If it does it fails the firmness test. Above is an image showing our mattress passing this test. You can see the metal ball is not sinking in and touching the inner circumference edge of the metal plate. 

2 - Microporous Barrier Cover -

This is the magic barrier layer. It is permanently encasing the mattress core and never removed. 

waterproof and breathable microporous mattress encasement cover

The vital requirements for this component are:

  • It completely stops any liquid mess or wet accidents from going inside of the mattress core. Otherwise we risk bacteria and mold
  • It stops the passage of dust mites getting into the core and having a poo party. Its their poo pellets that become the allergen trigger
  • Even being waterproof, it will still allow baby's skin to breathe. Otherwise it will cause a clammy environment for your baby. Consequently creating a great discomfort due to overheating and more sweating than normal. Gore-tex invented this waterproof breathable fabric membrane in 1969 and since then these microporous materials have become better and better. Ours has a very good low ret value meaning great skin breathability while crucially being still waterproof to keep the mess out. Many mattress toppers or mattress covers will say breathable as an over exaggerated marketing claim on their product. But ours has gone through the tests to prove and completely substantiate what we are claiming. And this we are very proud of. In essence, if a product says its waterproof and breathable and yet is somehow still very cheap, then this is where you should be quite dubious.

Quality does cost extra and this would be our most expensive component, but because of it's amazing properties it is vital to our whole baby mattress concept.

  • A surface easily wiped down thereby eradicating the build up and exposure to dust mites and their poo. Anti dust mite chemicals will never take care of the poo which is the trigger.
  • A surface cleaned easily after wet accidents. Especially in the early hours of the morning when we are tired and falling off our feet, and we just need to get baby back onto a clean sleeping surface ASAP. While not so possible or easy with inconvenient zipped covers and wet mattress cores, but so quick and easy with our super microporous material and dry core that we are all back in bed and comfortably asleep in no time at all. 
  • A surface cleaned easily of pollen, dust, pet dander, and dry dead skin cells (the dust mites food).

This microporous encasement cover has also been tested in accordance with US regulations and found to have no harmful chemicals or phthalates. Its also meets OEKO-TEX Standards.

3 - Elasticated Comfort Cover -  

a polyester unique microfilaments material developed in Europe. It combines softness with optimal micro ventilation. What this simply means is that the airflow ability of the material will carry the moisture away and help evaporate any sweat. It is a temperature control that will not be a cause of overheating for your child. It is easy to hand or machine wash at 40°C and tumble dry at low temperatures. This material makes it a very comfortable sleeping surface for your baby.  Its also meets OEKO-TEX Standards.

That's it or "Sin é" as we say in Ireland - Plenty of Thought, Simplicity & Practicality in design while creating a Superior Healthy & Safer Sleep Environment for your baby which is backed up by scientific testing by AAFA & ASL - the asthma & allergy friendly® certification partnership.
