Which MATTRESS Is Right for Which Age?
A Guide to Development, Sleep Needs, and the Right MATTRESS for Babies and Children
What kind of mattress does my baby need? When is the right time to switch to a bigger bed? And how can I tell if my child’s current mattress is still appropriate for their Age?
Especially in the first few years of life, your child’s sleep patterns are constantly changing. A newborn who needs many short sleep periods grows into an active toddler, and later into a school-age child with a growing body and entirely new needs for comfort and support of the body. That’s why the MATTRESSES should always be suited to your child’s current stage of development.
In this guide, we’ll show you which MATTRESSES are best for each age group, what your child’s approximate sleep needs are, which bed is right for which stage, and what you should pay special attention to when choosing baby and children’s MATTRESSES.
1. Why does the right mattress depend on age?
Children’s sleep isn’t the same in every stage of development. Newborns need significantly more sleep than preschoolers—and a different sleeping environment as well. Height, weight, sleep patterns, and needs are constantly changing. That’s why the question “Which mattress for which age?” is so important. A good mattress isn’t just comfortable—it also ensures greater safety in the crib. For babies, other factors often take priority: safety, stability, and breathability. For toddlers and older children, factors such as optimal lying-comfort and durability take center stage. For teenagers, ergonomics, pressure relief, and long-term body support are key.
Which Mattress for Which Age? A Quick Overview
| Age | Approx. sleep needs | Suitable bed | Ideal mattress |
|---|---|---|---|
| 0–6 months | Approx. 14–18 hours | Co-sleeper, cradle, or crib | Firm, well-fitting, and breathable baby mattress |
| 0–5 years | Approx. 10–16 hours | Baby crib or cot | Dimensionally stable baby mattress with good ventilation |
| Ages 1–2 and up | Approx. 8–16 hours | Crib, floor bed, or toddler bed | Durable, hygienic, and medium-firm mattress |
| 5–12 years | Approx. 9–12 hours | Children’s bed, often 90 × 200 cm | Ergonomic, point-elastic children’s mattress |
| Ages 12 and up | Approx. 8–10 hours | Teen bed, usually 90 × 200 cm to 140 × 200 cm | Teen mattress with pressure relief and a 7-zone design |
Sleep duration is a general guideline. Some children need significantly more sleep, while others need a little less. More important than an exact number of hours is whether your child seems alert, balanced, and well-rested during the day.
An important basic rule when buying mattresses for babies and children
No matter the age, there are certain features that are essential for every children’s or baby mattress.
The mattress shouldn't be too soft
Babies, in particular, should sleep on a firm, dimensionally stable surface. A mattress that’s too soft allows your baby to sink in, which can lead to CO2 rebreathing.
The mattress should be Breathable
Children—especially babies—are not yet able to regulate their body temperature properly. The MATTRESSES should therefore effectively wick away heat and moisture
The cover should be Washable
With babies and toddlers, accidents can happen quickly—spilled milk, a leaky diaper, or other small mishaps. That’s why the cover should be removable and washable.
Adult mattresses are not automatically suitable for children
Children have different body proportions than adults. Especially for babies and toddlers, the focus is not on zoned support but on a stable lying-surface.
0–6 Months: Which Mattress Is Best for Newborns
During the first few months, your baby sleeps a lot. Sleep is usually spread out in short periods throughout the day and night. A regular sleep pattern doesn’t develop until later.
Newborns especially need security, closeness, and a safe sleeping environment.
Which bed is suitable?
For the first few months, a co-sleeper or a crib is ideal. It’s important for the baby to have their own sleeping space while still being close to the mother. The bed should be sturdy, and the mattress should fit perfectly. The crib should be free of stuffed animals or duvets, as these increase the risk of suffocation in the crib.
Which mattress is best?
For newborns, you should choose a firmer mattress that is highly breathable and fits the crib perfectly.
It should:
- be breathable—both the cover and the core—so that moisture and heat can be wicked away
- be equipped with integrated wetness-protection
- not be too soft but also not too hard
- fit the crib exactly
- have a removable, washable cover
- be made of non-toxic materials and, ideally, manufactured according to DIN standards.
At this age, safety is more important than comfort.
0–5 Years: Which Mattress Should You Choose as Your Baby Grows?
Starting around 6 months, babies often outgrow a co-sleeper and become more active. This can quickly lead to more restless sleep. It’s therefore often time to switch to a separate crib.
Which bed is right?
During this phase, a baby crib or cot is often ideal. If it’s height-adjustable, it can be used as a co-sleeper right from birth. It provides a safe boundary and is therefore ideal for a baby’s first attempts at standing. Typical sizes are 60x120 and 70x140 cm.
Which mattress is best?
The best mattress for babies from 0 to about 1.5 years old is on the firmer side. After that, the mattress can be more comfortable but should still provide good support. Reversible mattresses that adapt to your baby’s weight are ideal. For the early stage between 1 and 1.5 years, a safety edge is recommended. The sturdier edge of the mattress protects your baby during their first attempts at standing and provides more stability without slipping or getting pinched. In addition, integrated wetness-protection is a good idea, as small accidents can still happen frequently at this age.
It’s important to have:
- firm support
- optimal air circulation
- washable, removable cover (ideally with wetness-protection)
- optimal fit (maximum 3 cm gap from the bed frame)
- Optional safety edge—for those first attempts at standing.
1 to 2 Years: Which Mattress Is Best for Active Toddlers?
Between the ages of one and two, a child makes great strides in development. They become more active and agile and need less physical closeness. Many children start walking and want to explore their surroundings on their own. Children’s sleep often becomes more restless, as they have to process many new impressions and experiences at this age.
What kind of bed is suitable for children between 1 and 2 years old?
Many children between the ages of 1 and 2 still sleep in a crib. This allows parents to rest assured that their child is safe, as they cannot climb out of the crib on their own. If you’d like to give your child the opportunity to become more independent, a floor bed is the ideal choice. With their low entry point, they’re safe and allow your child to get up on their own. Important for a floor bed: the mattress shouldn’t rest directly on the floor. A slatted frame is ideal, as it allows moisture to be wicked away effectively.
Which mattress is best for the early transition to a floor bed (ages 1 to 2)?
The mattress for a floor bed can range in size from 90x200 cm to 140x200 cm, depending on the bed. It shouldn’t be too firm and should provide optimal support for your baby. It’s important that it’s highly breathable and free of harmful substances. In addition, optimal support is crucial; the mattress should adapt perfectly to your child’s body contours and ensure healthy development of the head and spine. Floor bed mattresses can be used well into the teenage years, which is why high-quality and durable materials are essential. However, when transitioning to a floor bed at an early age (from about 1 year to around 2 years), you should choose a slightly softer mattress without a 7-zone design.

Which mattress is best for a child’s bed from age 2 through the teenage years?
When your child moves into their own bed, they need optimal support for their spine and head. This is the only way to ensure proper development even while they sleep. If your child is already older, mattresses with a 7-zone design are ideal. These adapt perfectly to your child’s body, providing relief for the hips and shoulders and support for the spine. The different zones ensure a particularly ergonomic sleeping position.
For long-term use starting in early childhood, mattresses with two different firmness levels (reversible mattresses) are ideal. This is because the heavier your child is, the firmer the mattress should be.

Teenage Years: Which Mattress Is Best for Teens?
As children get older or enter their teenage years, it’s often time to switch to a larger bed—and thus a larger mattress. Beds measuring 120x200 or 140x200 cm are ideal for this stage.
As children reach school age, their daily lives become more demanding. They learn a lot, are active, are growing, and need to rest at night. Sleep is now crucial for concentration, recovery, and well-being. The mattress must now provide more ergonomic support than it did in the early years of life. In addition to hygiene and sleep comfort, ergonomic support becomes increasingly important.
The mattress should offer optimal shape retention and support. Breathable mattresses that are soft to medium-firm, maintain their shape well, and feature a 7-zone design are ideal.
The 7-zone design ensures optimal support and pressure relief. The mattress’s 7 distinct zones adapt precisely to your child’s body contours, preventing pressure points and providing optimal support for the spine—promoting an ergonomic sleeping position and healthy development.

2. Common Mistakes When Buying Mattresses for Children
There is no one-size-fits-all hardness level that is suitable for children. As a general guideline:
- Babies often need a firmer lying-surface
- Toddlers need a medium-hard, dimensionally stable MATTRESS
- School-age children through teenagers need MATTRESSES that offer point elasticity and support and adapt to their body weight
Mistake 1: The mattress is too soft
A mattress that’s too soft isn’t ideal, especially for babies. A mattress that’s too soft can cause the baby to sink in, which can lead to rebreathing of CO2 and increase the risk of sudden infant death syndrome (SIDS).
Mistake 2: The mattress doesn’t fit perfectly in the crib
Gaps wider than 3 cm between the mattress and the crib frame are not ideal. The mattress should fit the crib’s dimensions snugly. Otherwise, the child could get hurt or the mattress could shift out of place.
Mistake 3: The mattress is used for too long
Children grow quickly, so it’s important to choose a mattress that meets your child’s needs. Check regularly to make sure the mattress still provides proper support and is large enough. Youth mattresses should not be used for more than 7 years, as their support diminishes over time.
Mistake 4: Using an adult mattress
Adult mattresses are often not designed to meet the needs of children. Children are usually smaller and lighter than adults. Age-appropriate mattresses are generally the better choice for children.
3. Conclusion: Which Mattress Is Right for Which Age?
The right mattress changes as your child grows. For babies, a firm, safe, and breathable baby mattress is ideal. During the toddler years, when your child becomes more active, it’s important that the mattress provides optimal support—it shouldn’t be too soft, but it should support your child as they take their first steps. (Mattresses that you can easily flip are ideal here—this way, you can adjust the mattress to your child’s weight and won’t have to keep buying new ones.) For children around 2 years and older, a larger and more ergonomic children’s mattress makes sense. Teenagers, finally, need a mattress that reliably supports their height, weight, and sleeping position. Reversible mattresses (which grow with your child) are therefore the best choice here.
If you’re wondering, “Which mattress for which age?”, don’t just focus on age. Height, weight, activity level, needs, bed size, safety, and sleep environment are also important.
This creates a sleeping environment that supports your child well through every stage of development—from the first crib to a youth bed.
