We Reviewed the 5 Top-Rated Cot Mattresses

Finding the perfect crib with the safest, more comfortable cot mattress for your baby will imply serious research. It is easily noticeable for parents when the baby is not comfortable enough during their sleeping hours. 

Over the years, cot mattresses manufacturers have been changing their inner compositions in their crib mattresses to make them safer for parents to acquire. The biggest fear of any parent with a newborn at home is the inherent risk of SIDS (sudden infant death syndrome) which is a medically unexplained condition that causes death in babies younger than a year old, during their sleep, in their cribs. 

Lamentably, no crib/cot mattress in the market fully prevents SIDS. Do not be fooled if a certain brand claims that their crib mattresses do. The harsh truth that some manufacturers don’t want you to hear is that only safe sleep practices will reduce the risk of SIDS, but not fully prevent it, but yes; getting a safe cot bed plays a key role in terms of prevention. Then, it is a good idea to surround your baby with the safest, more breathable possible fabrics when they are at ease; remember, small babies can sleep up to 18 intermittent hours a day. 

Suffocation, sweating, overall discomfort, and allergies are also a great concern for parents with small babies; this is why, in this buying guide, we have done extensive research by choosing brands in the crib mattresses market that are responsible and empathetic with parent’s concerns in regards of their babies sleeping time.

If you are the responsible parent of a baby that wouldn’t allow you to sleep properly at night, you may want to read this guide to find a great cot bed for your child. Although we can’t assure you, you will sleep better after buying the perfect cot mattress, we hope your baby will be much more comfortable on their crib!

Cot Mattress Buying Guide

Finding the Ideal Cot Mattress for Your Baby

Before you click on “buy” or you slide your credit card at a department store, there are a few important points to take into consideration before getting your baby cot mattress:

Size does matter: Whereas the standard cot mattress size is around 51 to 53 inches long and 27 to 28 inches wide (approximately 140 x 70 cms) and their thickness can vary between 4, 6 inches, you need to measure your crib, before buying a cot mattress that may not be a good fit by showing gaps on the sides of the crib making it unsafe for your baby. Or that is too bulky it gets deformed once you push it into the crib.

Also, bear in mind there are mini cot mattresses of different sizes that will come in handy for ‘pack and play on the go’ beds or portable cribs. Some mini crib mattresses come with the advantage of being flippable for dual side use.

Materials and overall composition: The crib mattress that you choose must come with the necessary firmness that will help your baby cuddle but not sink into an unsafe mattress. Many cot mattresses are composed of memory foam inner layers that give extra support and breathability, some of them have cool fabrics that cover the whole mattress. Getting a waterproof mattress will always be a good idea, as leak accidents happen often, and removing stains from crib mattresses may be a hard task for parents.

Also, babies tend to be tummy sleepers; and as funny as it seems, some of them would even prefer to be head sleepers making it hard for parents to find a breathable mattress with a soft cover they can breathe through. 

Checking the weight support of the cot mattress will also guide you on whether it’s a mattress that will stay with your child as they grow old. Stage 2 crib mattresses, for example, will be ideal for cribs and can be used as toddler beds later on.

Cot Mattress Shopping Tips

Whether you buy online or you prefer to visit the physical store, checking your desired mattress for important certifications like Certipur-US and Green Guard will give you guidance about the safety of your crib mattress. 

Reviewing the return/refund policies, the delivery info, and the warranty of your mattress are a must if you want to have peace of mind, that if the product comes defective or for a reason, it was not suitable for your toddler you can return it. Some outstanding brands that manufacture great cot beds, single cot beds, twin cot beds, and memory foam crib mattresses could be Newton, Graco, Bubble bear, Serta, Milliard, among others.
