It has a super smooth quilted surface on top of the foam that is comfortable and supportive, so that will allow your baby to have a relaxing night’s rest. The sturdiness of this cot mattress is ideal for the newborn baby and also the infant.

Meanwhile, some customers have said that it may have a strong chemical smell when you first buy the mattress; however, this smell should disappear after airing the cot mattress out for a few hours. Because cot bed mattresses are usually quite firm due to the level of support that a newborn needs, some customers have said that this cot mattress is firmer than they wanted.

Waterproof

It is very important to consider whether the mattress is waterproof or has a waterproof cover. Since babies are learning to control their bladder, there will be accidents at bedtime.

Many cot bed mattresses come with a waterproof layer that doubles as a removable and washable cover. Making sure that you have a waterproof cover or mattress protector will save you a lot of time and money, as you will not have to buy a new mattress every time your baby has an accident.

Support

In their early stages, babies are learning how to move, roll and lift their weight. Therefore, you will need to look for a cot bed mattress to support your baby while they are sleeping.

If a mattress is too soft, your baby will not be able to roll out of the indent and breathe safely. Making sure you have a safe cot bed mattress means that sudden infant death syndrome is unlikely.

A strong supportive material also helps your baby grow safely, as their head, neck and spine alignment will be supported during their sleep, which is when a baby will continue a lot of their development.

Cot Mattress Sizes

Cot beds come in different sizes, and so you will want to find the right one to fit your cot bed.
