How to Choose the Right Co-Sleeping Bed: 7 Essential Criteria

The first co-sleeping bed I used was a borrowed model. At that time, I wasn't fully aware of what criteria to compare. It wasn't until several months later, after purchasing my second co-sleeping bed, that I realized what truly makes a difference in daily life.

In this guide, I will outline the 7 key criteria that matter when selecting a safe, practical co-sleeping bed that fits your lifestyle, helping you avoid common pitfalls and ensuring your investment pays off in the long run.

Why I Wrote This Guide

💛 My Personal Experience

I've used two co-sleeping beds with my children. The first was a Chicco model that we borrowed. A few months later, when it was time to choose a co-sleeping bed for my second baby, I was no longer starting from scratch. My initial experience had taught me that the small details we often overlook before the baby arrives can significantly ease nighttime routines.

This time, I wanted a model that would fit perfectly with our bed, include a proper storage basket, offer multiple height adjustments, and have an inclined sleeping surface. This led me to select the Maxi-Cosi Iora Air, which I still use today.

Reflecting on both experiences, I realized that choosing a co-sleeping bed goes beyond just design or brand; certain criteria have a profound impact on daily life, while others are less significant. It is these crucial factors that I aim to help you identify in this guide.

⚡ In a Hurry? Here Are the 7 Criteria at a Glance

If you're pressed for time, here are the seven points to check before purchasing a co-sleeping bed:

✅ Ensure the co-sleeping bed is compatible with your bed (height, legs, and attachment system).

✅ Confirm it meets the EN 1130 safety standard and has a reliable attachment system.

✅ Choose a model with sufficient height adjustments and, if necessary, a slight incline for the sleeping surface.

✅ Don't overlook the mattress: it should be firm, breathable, and suitable for a newborn's sleep.

✅ Check how long or how much weight the bed can support, as well as its potential for evolution.

✅ Consider practicality in daily use: wheels, storage baskets, assembly, and transport—these small details can greatly simplify the initial weeks.

✅ Finally, compare quality-to-price ratios rather than just the price. A slightly more expensive model may be worthwhile if it lasts longer or is easy to resell.

1️⃣ Compatibility with Your Parental Bed

One criterion you should verify before comparing different models is compatibility. A co-sleeping bed might have an excellent mattress, numerous adjustments, or high-quality finishes, but if it doesn't fit properly with your bed, you won't fully benefit from its advantages.

Before purchasing my second co-sleeping bed, this was the first aspect I checked. I wanted a model that could align perfectly with our box spring, without any need for modifications or compromises. This is also why I opted for a model with multiple height adjustments.

Check the Height of Your Bed First

For the co-sleeping bed to serve its purpose effectively, its mattress must be level with yours. If the co-sleeping bed is too low, you will have to bend down more to pick up or lay down your baby. Conversely, if it is too high, it will be impossible to create a seamless transition between the two sleeping areas.

Before making a choice, take a few moments to measure the height of your mattress from the floor, then compare it with the adjustment range provided by the manufacturer. The more height positions a model offers, the better your chances of finding a perfectly suitable adjustment.

Also Consider the Shape of Your Bed's Legs

This is a detail that often goes unnoticed until installation time. Depending on the models, the legs of the co-sleeping bed must fit under your bed. If your bed has a thick frame, built-in drawers, or a unique design, some co-sleeping beds may not be able to get close enough.

In such cases, you may need to use specific adapters if offered by the manufacturer or choose a model compatible with that type of configuration.

Check the Side Opening

Not all co-sleeping beds offer the same side opening. Some provide a wide opening that facilitates breastfeeding, bottle-feeding, and the many small awakenings of the first weeks. Others leave part of the side barrier in place, which can make accessing your baby a bit less convenient.

If, like me, your goal is to minimize nighttime trips, this detail can significantly enhance your comfort.

My Experience

When I chose the Maxi-Cosi Iora Air, I knew I wanted a model that would easily adapt to our bed. The numerous height adjustments allowed me to align it perfectly with our box spring, and I encountered no difficulties during installation.

In daily use, this has been a true comfort. I can pick up my baby in my arms or lay him down without needing to stand up completely, which makes a real difference when facing multiple awakenings in one night.

🔎 What to Check Before Buying

Before finalizing your choice, take a few minutes to verify these five points:

📏 Is the height of your bed compatible with the adjustments of the co-sleeping bed?

🛏️ Do the legs and frame of your bed allow the co-sleeping bed to be positioned as close as possible?

🔒 Is the attachment system suitable for your bed (straps, hooks, etc.)?

👶 Is the side opening wide enough to facilitate nighttime awakenings?

↕️ Does the co-sleeping bed offer enough adjustment positions to fit your setup?

2️⃣ Safety: The EN 1130 Standard and Attachment Systems

While design and options are straightforward to compare, safety often hinges on less visible details: bed stability, attachment systems, locking mechanisms, and the design of the sleeping area.

A well-installed co-sleeping bed should allow your baby to sleep in their own space while remaining close to you. It’s not enough to simply lower one side of the bed; the entire unit must remain stable and ensure no dangerous gaps exist between the parental bed and the baby’s bed.

Fortunately, there are standards that help ensure a model meets specific safety requirements.

Check That the Bed Complies with the EN 1130 Standard

The European standard EN 1130 outlines safety requirements and testing methods applicable to cribs, including co-sleeping beds. Verifying that a model complies with this standard is a good first step when comparing several beds. However, this does not exempt you from adhering to the installation and usage conditions specified by the manufacturer.

Look at How the Co-Sleeping Bed Attaches to the Parental Bed

Not all manufacturers provide the same attachment system. Depending on the models, the co-sleeping bed may be secured using straps, hooks, or other devices designed to prevent it from drifting away from the parental bed during the night.

Regardless of the chosen solution, the goal remains the same: to avoid creating a gap between the two sleeping areas. Always take the time to follow the instructions during installation and ensure that the system is correctly in place.

Stable Legs, Lockable Wheels, and Breathable Sides

The stability of the bed does not solely depend on its attachment system. Non-slip feet or wheels equipped with brakes minimize unwanted movement when you pick up your baby or slightly shift the co-sleeping bed.

Another feature I particularly appreciate is the breathable mesh sides. In addition to promoting good air circulation, they allow you to keep an eye on your baby throughout the night. Personally, I find this detail very reassuring, especially during the first few weeks.

A Secure Sleeping Area is Essential

Even with an excellent co-sleeping bed, certain safety rules remain crucial. For sleep, your baby should always be placed on their back, on a firm mattress that fits snugly in the bed.

Avoid adding a bumper, pillow, thick blanket, or stuffed animals in their sleeping space. Keeping the sleeping area clear is the safest option during the initial months.

🔎 What to Check Before Buying

Before making your choice, ensure the model:

✅ complies with the EN 1130 standard;

✅ has a reliable attachment system;

✅ features stable legs and, if applicable, lockable wheels;

✅ includes breathable sides for better air circulation;

✅ provides a firm and well-fitting mattress.

3️⃣ Height and Incline Adjustments: Options That Really Ease Nights

When it comes to height and incline adjustments, the more options available, the better. A simple adjustment mechanism is essential, especially when you are holding your baby in your arms.

Additionally, an incline can be beneficial in cases of reflux. Be sure to check the locking system as well.

🔎 What to Check Before Buying

Before finalizing your choice, verify:

✅ the number of height adjustments available;

✅ the ease of adjustment with a baby in your arms;

✅ the incline option and its locking mechanism.

4️⃣ Mattress: A Crucial Factor for Comfort and Baby's Safety

A firm mattress is essential for your baby's safety and comfort. Good ventilation is also a significant advantage. Consider the cover and materials used, and remember to replace the mattress when necessary.

🔎 What to Check Before Buying

Before making your decision, ensure the mattress:

✅ is firm;

✅ provides good ventilation;

✅ has a suitable cover and materials;

✅ is easy to replace when needed.

5️⃣ Evolution and Duration of Use: Consider the Future

How long can a co-sleeping bed be used? In reality, every family has its own pace. Some models evolve with your child, and it's also worth considering resale potential.

🔎 What to Check Before Buying

Before making your choice, check:

✅ the age or weight limit for the co-sleeping bed;

✅ the evolution options available;

✅ the resale value.

6️⃣ Practicality and Options: The Small Details That Make a Big Difference

A simple assembly process is always appreciated. Wheels can facilitate movement, and a storage basket is something I found more useful than I initially expected. Features like a rocking function, mosquito net, or reducer—are they truly necessary?

🩷 My Advice

Consider your specific needs and preferences when evaluating these additional features.

7️⃣ Value for Money: Compare Features, Not Just Price

A more expensive model might be more advantageous in the long run. Conversely, there's no need to pay for features you won’t use. Always check what is included in the price.

🩷 My Advice

Make a list of must-have features and compare them across different models to find the best value for your investment.
