Buying a Baby Cot: Sizes, Safety Features and Suitable Models for Every Family Situation

A baby cot needs to fit more than just your bedroom or nursery. It should also be compatible with the mattress, your child’s height, the existing bed structure and how long you plan to use it. Many purchasing decisions go wrong not because of the design, but because of small details: incorrect dimensions, unsuitable height adjustment or a conversion that requires additional accessories.

This guide explains which features matter before you buy and which model suits different everyday situations.

Common Pitfalls When Buying a Baby Cot

1. Confusing the Overall Dimensions with the Mattress Size

A baby cot described as 60 x 120 cm has a sleeping area measuring 60 x 120 cm. However, the overall dimensions are larger. For example, the roba Fold-Up measures 123 x 64.5 x 77 cm. The overall dimensions therefore determine how much space it takes up in your bedroom, while the stated sleeping area is the only measurement that matters for the mattress.

The mattress should fit the cot exactly. There must be no safety-critical gaps between the mattress and the frame. A 70 x 140 cm baby cot therefore requires a mattress measuring exactly 70 x 140 cm.

2. “Grows with your child” Does Not Always Mean a Complete Conversion

A baby cot that grows with your child can cover several stages of development. However, conversion options vary considerably:

  • A 3-in-1 baby cot can, for example, be used as a bedside cot, cot and toddler bed.
  • Depending on the model, a 4-in-1 baby cot may offer additional configurations such as a cradle, bench or junior bed.
  • With some cots, conversion sides or other accessories are available separately.

Before buying, make sure you know which components are included and from which stage of your child’s development the conversion is intended.

3. Castors Without Brakes Can Become a Safety Risk

A baby cot with castors is easier to move to another room. However, the castors must be securely locked when the cot is stationary. The same applies to a folding baby cot, which must be fully locked after assembly. Castors are not a substitute for secure attachment when the cot is used as a bedside cot next to the parents’ bed.

The Most Important Selection Criteria

Size and Length of Use

The dimensions 60 x 120 cm are often suitable for a classic baby and toddler cot. Models measuring 70 x 140 cm offer a larger sleeping area and may be suitable for longer use, depending on their design. The manufacturer’s information on age, height and maximum load is always decisive.

One example is the roba combination cot measuring 70 x 140 cm. It has three height positions and can be converted into a junior bed. The stated period of use ranges from birth to approximately the age of seven. However, when it can no longer be used as a cot depends on the child’s development. As soon as your child can climb out independently, the cot configuration should be changed.

Height Adjustment and Attachment

An adjustable-height baby cot makes it easier to place your baby in the cot and lift them out again. With a bedside cot, the height must match the mattress of the parents’ bed. You should therefore check:

  1. Which height settings are available?
  2. Is the height compatible with the structure of the parents’ bed or divan bed?
  3. Is attachment with straps or brackets provided for?
  4. Are there any restrictions on the thickness of the bed frame?

According to the product information, the roba Safe Asleep bedside cot can be adjusted to seven positions between 22.4 and 44.6 cm. A separately available extension set may be required for special types of bed.

Safety Information and Care

Look for a clearly stated standard, easy-to-understand assembly instructions and regular checks for screws, connections, castors and height-adjustment mechanisms. For the 60 x 120 cm model, DIN EN 12227 is specified, while other roba models refer to EN 1130 or EN 716.

This information does not replace an assembly check. All connections should be secure before every use. Damaged or missing parts are grounds not to use the cot. Use only the correct mattress and avoid additional pillows, soft padding or inserts that are not intended for the sleeping area.

Baby Cot FAQ

How long can a baby cot be used?

This depends on the sleeping area, the manufacturer’s specifications and the child’s development. A 60 x 120 cm cot is often used from the newborn stage through to the toddler years. A 70 x 140 cm model or convertible cot may be suitable for longer use if properly equipped. As soon as a child can climb out independently, cot use should end and the intended conversion should be checked.

What is the difference between a bedside cot and a cot?

A bedside cot is usually smaller and designed to attach to the parents’ bed. A cot normally stands independently in the room and offers a larger sleeping area. Some models combine both functions and can later be used as a toddler or junior bed.

Are castors useful on a baby cot?

Castors can be practical when moving the cot between rooms. They must always be locked when the cot is stationary. When using it as a bedside cot, the specified attachment to the parents’ bed is also required. Before every use, check that the brakes, connections and frame are undamaged.
