Babies and toddlers spend more time asleep than awake, which is why selecting a cot bed mattress for your child is essential.

Babies spend between 13 and 16 hours per day sleeping. Therefore, you have to make a choice that can be hard and overwhelming. Do not worry, we are here to help!

Here in LightSleeper, we test each product we review and thoroughly inspected it for a set number of days. However, we are non-professionals in the medical field and these only recommendations. With that said we’ve carefully selected the Top 5 Cot Bed Mattresses for 2021 so that you can make an informed decision.

Best Cot Bed Mattress

What to consider when buying a Cot Bed Mattress?

Next, we will try to help you with a few explanations and features that have to be taken into account before making a purchase. They are the following:

Base

Selecting a base is something that can be beneficial for your baby as it grows. If you choose an adjustable option, you will typically find it with three positions.

Those positions can be switched with your baby’s growth. Every cot bed base will come with instructions, and in them, you can find the recommendations for the specific levels a set product offers. By selecting the appropriate base, you give your child a better chance at blissful sleep, and possibly a longer rest for yourself.

Mattress

No matter if you choose a cot or a cot bed, you have to get the right type of mattress to go in it.

Even if you’re using a second-hand base, we recommend that you buy a new mattress so that you can make sure its dust free and hypoallergenic. You should look for a product that is on the firmer side and fits your bed with no gaps.

Usually, mattresses and cot beds are sold separately, which gives you the choice of different types. If you don’t know what they are, we will discuss them later on in the article.

Size

Cots are often smaller than cots beds. Even though there’s a lot more variation in sizes when we talk about cot beds, they are generally quite similar.

Usually, that’s around 145cm long, 100cm tall and 75cm deep. Most options will have side rails between 84-87cm high in the highest position. Sometimes that can be a challenge for a shorter person to reach over.

That’s why you should consider a product with a drop side that will reduce this height and make it easier for you to reach your child. Lastly, don’t forget to measure the space you have in your bedroom or the nursery you will be using.

What to consider when buying a cot bed mattress

Wood or Not?

The material used for the bed will showcase its durability and quality. Some choices are better than others, but people typically decide between wood or MDF (engineered wood product).

Of course, the cost and quality will depend on the type of wood. When you’re making a decision check on the label whether the mentioned material is used throughout or is only a finish on top.  

Teething Rail

Chewing the edge of a cot is a habit that many babies have. That can be dangerous for a baby or a toddler since it can cost damage.

However, you can prevent that by choosing an option with a teething rail. The protective covering on the side edges will help protect the cot and most importantly, your kid.

Casters

If you’re planning on continually moving your cot bed from one room to another, you might want to consider casters or mounted wheels. They can come in handy, plus with them, it’s going to be much easier for you to clean underneath the bed so that no specks of dust stay around your child.

What size cot mattress do I need?

What size cot mattress do I need?

The size of the mattress will depend on your choice. In the UK, the standard option is 60 x 120cm, but if you’ve purchased your bed from elsewhere, you have to check the required size.

For example, baskets, cribs and co-sleepers require smaller mattresses designed for that purpose. A cot bed is often larger and will need the mattress to be 70 x 140cm.

No matter what mattress you’re buying, always check its dimensions before you make a purchase. You can do that either online or with the retailer.

How thick should a cot mattress be?

This is one of the most important questions you should be asking yourself before getting a cot mattress. Kids concentrate their weight on a small mattress area, meaning sagging and hitting the cot bed beneath.

To avoid that we recommend selecting an option that’s at least 10cm thick and firmer rather than softer. You want to make a choice that will support your child’s body and head and won’t sag. If you don’t know how to choose an option, you can visit a store and squeeze at the edges and in the centre to decide.

What are the cot mattress safety guidelines?

What are the cot mattress safety guidelines?

Every parent cares for their kid’s safety. That’s why we’ve created a shortlist of things you can do to improve it further and make sure your baby is as safe as it can be.

  • Even if you’re using the same cot bed, get a new mattress to prevent any instances of hygiene-related issues
  • Make sure that the cot bed and the mattress are the same sizes
  • Select a firmer mattress to avoid sagging, while ensuring your child receives the need support
  • Pick an option that includes BSI number, which will ensure the product you’re buying is in line with British Standards for safety.
  • A cot is suitable for newborns up to 2 years of age
  • A cot bed is suitable for babies from birth to 4 years of age

What types of cot bed mattresses are there?

What types of cot bed mattresses are there?

As we mentioned above the type of cot bed mattress you choose is essential for your baby’s comfort and support. Here are the three most common types found in the UK:

Foam Cot Bed Mattresses

Usually, this type is made from polyfoam, which generally varies in firmness level from medium-firm all the way up to firm.

Those levels are regarded as safest for babies. Foam options are often the most affordable choice. The support they offer depends on the mattress thickness and density.

Layered foam doesn’t generate much noise, and that’s a plus when it comes down to movement. However, it offers less edge support compared to others.

Pocket Sprung  Cot Bed Mattresses

This type features springs which are individually wrapped within a cloth sleeve.

Pocket sprung options adapt to your baby’s movements for enhanced support and comfort. The reason behind it are the pocket springs that adapt to your baby’s movements through the night.

Also, pocket sprung cot bed mattresses are heavier with above-average life spans and tend to produce less off-gassing.

Hybrid Cot Bed Mattresses

Lastly, we have the hybrid option, which is pretty much a combination of the two types above. They come with a pocket sprung layer and upper foam layers for comfort.

Just like the sprung ones, they are on the heavier side and have longer life spans. Most hybrid choices offer excellent support and firmness to reduce rollover. However, they can be more expensive as opposed to foam options.
