Cot mattress size and dimensions

Cot mattresses for babies are significant. So, choosing the right one matters. Here are some of the different dimensions of cot mattresses that will help you decide which works best. 

Standard cot mattress size in Australia

The standard cot mattress size in Australia is 1300 x 690mm with a tolerance of 20mm above or below. This size is suited to full-sized cots and is important to ensure a safe and secure fit for the cot, as advised by Red Nose Australia. Other sources also confirm the standard cot mattress size to be 69 cm wide and 130 cm long.

Additionally, specific brands may have variations in mattress sizes, so it's important to check the recommended mattress size printed on the cot packaging by the manufacturer to ensure compatibility.

Large/ Borri size

This is a standard cot mattress in Australia. This mattress measures 132-135 cm x 77 cm. There are a few minor variations in the measurement. It is, therefore, best to check the bed linen size as well. Boori Cot is another name for the large size. 

US standard size

In Australia, the US Standard size is the most popular and widely used cot mattress. This cot mattress measures 130 cm x 69 cm. There can sometimes be slight variations in the measurement, and the size may come to around 129 cm x 68 cm. That is why it is important to check the size of the bed linen before buying it. 

UK large

This particular kind of cot bed measures 140 cm x 70 cm. In terms of size, it is the largest in Australia. It might be difficult to find bed linen in this size. But it is not very common, and people don't reach for it as often as others. 

How to choose a good cot mattress

Mattresses for babies are significant. It can either help them sleep well or make them cry all night. Finding the perfect cot mattress for your baby is the trick. When you know what to look for in a mattress, you can easily select the right one. If you do not know how to buy a mattress, here are a few things to keep in mind.

Firmness is important

For a long time, most parents believed that firm mattresses are ideal not only for babies but adults as well. But there is no universal and agreed-upon definition of how firm a mattress should be. Luckily, these days, there are standard tests to determine the firmness of a cot mattress.

Most mattress manufacturers are now required to comply with the standards. They need to test their products before distributing them to the market. A firm bed is vital for the safety of toddlers. 

Check for the right fit

One of the most important things to remember is that the mattress should fit the cot. This is primarily for safety reasons. There should never be a gap measuring 4 cm or even more between the cot and the mattress. 

Conversely, if the mattress is too tight, the shape might deform and spoil quickly. When this happens, toddlers can easily use the bundled-up sides to climb. 

Nowadays, mattress manufacturers put the dimensions on the mattresses. So you will have no problem finding out how much they measure. Make sure you measure the cot you have before going out to purchase a cot mattress. Thickness is also something you should keep an eye out for. There should be at least a 50 cm distance from the top to the bottom of the mattress. 

Material is another factor

The construction of a cot mattress is also an essential factor to consider when buying one. There are so many types of mattresses, such as ones made of foam, springs, and even latex. All these types have their firmness of standard and accepted quality, so it all comes down to personal preference.

It is best to find a cot mattress without quilted features. This is because mattresses that are extremely flat and do not possess undulating features will most likely pass the firmness test. A baby does not need a cushioned surface to sleep on. 

Other features

It is interesting to note that mattress manufacturers offer a lot of great features in their mattresses these days. So, what are these features you need to know? Well, one thing you should look out for is an anti-skid cot mattress. These are mattresses that do not slip easily when the infant or toddler is moving in the crib. This is because the base is made of anti-skid material. 

Mattresses with waterproof covers are also an ideal choice. Make sure the cover is soft to prevent any rashes. A breathable and removable cover will be your best option since it's hygienic and easy to clean.

The cooling feature is also an important thing you should consider. If you get the cot mattresses with anti-microbial holes, your toddler will remain cool. It does not trap odour and allows for a clean, cool, and hygienic sleep.
