Buying a children's bed: sizes, safety features and suitable models for every age

A children's bed needs to offer more than just good looks. Parents need to consider a suitable sleeping surface, sturdy materials, an age-appropriate way in and a design that can adapt as their child grows. At the same time, decorative motifs, supposed extra features and unclear age recommendations can make comparisons difficult.

Common mistakes when buying a children's bed

1. Confusing the external dimensions with the mattress size

A children's bed labelled 70 x 140 cm will usually have a sleeping surface designed for a mattress of this size. However, the external dimensions will be larger because of the side panels, headboard and footboard. Before buying, check whether the bed will fit in the intended space and whether you already have a suitable mattress.

With a 90 x 200 cm children's bed, the sleeping surface is considerably longer. This can extend the bed's useful life, but it requires more space and is usually not the first choice for babies.

2. “With fall protection” does not automatically mean it is suitable without restrictions

Depending on its design, a children's bed with fall protection may be intended for different age groups. With high or mid-sleeper beds, you must also check whether your child can climb up and down safely. A fitted safety rail does not replace checking the screws, connections and that the mattress is sitting correctly.

There is another point to bear in mind with cot beds: as soon as a child can climb out independently, the bed should no longer be used unchanged as a cot. A convertible children's bed can then be transformed into a junior bed or another intended configuration.

3. Accessories are not always included

A product image showing a mattress, pillow or bed linen does not necessarily indicate what is included in the delivery. When comparing products, parents should check specifically whether a children's bed with slatted base, side protection, conversion panels or textiles are included. Even with a children's bed with bed linen, the dimensions and care instructions may differ from those of textiles you already own.

The most important criteria at a glance

Sleeping surface and age

For babies and toddlers, a 70 x 140 cm baby bed is a common size. The key point is that the mattress fits the frame exactly, with no dangerous gaps. Models with height-adjustable slatted bases allow the sleeping height to be adapted to your child's stage of development. The higher position can make lifting out a baby easier; later, the slatted base can be lowered accordingly.

A junior bed measuring 70 x 140 cm may be suitable for the transition period. A 90 x 200 cm bed offers more space, but is generally intended for older children. Age recommendations, maximum load and design should always be considered together.

Materials and workmanship

A wooden children's bed may be made from solid wood, plywood, MDF or a combination of materials. These terms describe different materials and should not be treated as interchangeable. Important points include:

  • clear information about the frame, slatted base and surface finish
  • neatly finished edges and accurately fitting components
  • sturdy corner joints and screws that can be retightened regularly
  • a children's bed with slatted base whose support sits securely in the frame
  • care instructions for painted or untreated surfaces

For a model carrying the FSC label, check the specific certification and its scope in the product information. General environmental claims without verifiable evidence should not be the sole basis for your purchase.

Protection, access and assembly

Depending on the design, access rungs on cot beds can make it easier to put a child down or, later on, allow them to get in and out independently. With open Montessori-style designs, the focus is on easy access close to the floor. With a bed featuring a ladder, age, sure-footedness and adult supervision are particularly important.

Regardless of the design, the bed must be fully assembled according to the instructions. Packaging and small parts should be kept out of children's reach during assembly. The maximum load must not be exceeded.

Checklist before ordering

  • Does the mattress size exactly match the stated sleeping surface?
  • Are the mattress, slatted base, fall protection and bed linen included in the delivery?
  • Is the bed suitable for the child's age, height and weight?
  • Is conversion equipment required separately?
  • Will the external dimensions fit in the child's bedroom, including space for drawers or a ladder?
  • Are assembly, care and regular checking of the connections realistic for everyday family life?
  • For a high or mid-sleeper bed: can the child use the ladder safely, and will supervision be possible at first?

Frequently asked questions about children's beds

How long can a 70 x 140 cm children's bed be used?

This depends on the child's height, stage of development and the maximum load of the specific model. Many beds of this size are intended for babies and toddlers. With convertible models, use as a junior bed may be possible for longer, provided the specified conversion parts are used.

Which mattress fits a children's bed?

The mattress must match the stated sleeping surface exactly, for example 70 x 140 cm or 90 x 200 cm. It should sit in the frame without large gaps. Information about mattress height and delivery contents can be found in the relevant product description.

Is a Montessori children's bed suitable for every age?

A Montessori children's bed is usually low to the ground and allows children to get in and out independently. However, this alone does not establish a general age recommendation. Parents should take the manufacturer's specifications, the load limit and their child's motor skills into account. Younger children still require adult supervision.
