Buy Flexa mattress — Guide & Tips
The category "Flexa mattress" includes 18 models that are specifically tailored to the growing needs of children and adolescents. Whether for the first crib, the larger junior bed, or the durable youth bed – the right mattress influences sleep quality, spinal health, and your child's well-being for many years. When purchasing, pay attention to three core criteria: the material used, the firmness level, and the care properties.
Flexa predominantly uses two high-quality cover materials for its mattresses: Bamboo and Eucalyptus. Both are breathable, moisture-regulating, and naturally antibacterial – ideal for children who sweat at night or are prone to allergies. Bamboo fibers feel particularly soft, while eucalyptus has a cooling effect. In the core, one distinguishes between Cold foam mattresses (also referred to as “Flexa Matratze Sleep”) and Pocket spring mattresses. Cold foam provides even, point-elastic support and is lighter – good for beds that are frequently reconfigured or moved. Pocket spring mattresses are slightly firmer, more breathable, and suitable for heavier children or teenagers who need more support.
The size is a decisive factor: Most Flexa mattresses are available in 120 × 200 cm, fitting the common Flexa bed frames. Check the internal dimensions of the bed before purchasing – especially with Flexa beds with adjustable lying surfaces. A gap that is too large between the mattress and the bed edge can become a tripping hazard, while a mattress that is too small reduces lying comfort. Also pay attention to the total height: thinner mattresses (approx. 10–14 cm) are suitable for toddlers, while thicker models (from 16 cm) offer more stability for older children.
Another tip: choose the firmness level based on body weight. Light children (under 25 kg) are better off with a softer cold foam mattress, while children from 30 kg benefit from a medium-firm pocket spring mattress. Many Flexa models are reversible – one side slightly softer, the other firmer. This allows the mattress to 'grow' with the child. Don't forget the cover: all offered bamboo and eucalyptus covers are removable and washable at up to 60 °C – a great advantage for small accidents or soiling.
Popular Flexa Mattress
The three presented models cover the most common use cases: The Flexa Mattress Sleep with Bamboo Cover is the classic cold foam variant for the children's bed – light, adaptable and easy to care for. If you are looking for a firmer, more durable alternative, choose the Pocket spring core mattress with Bamboo Cover. It supports the spine more precisely and is suitable for children who move around a lot at night. The variant with Eucalyptus cover is the right choice if your child tends to overheat or sleeps in a poorly ventilated room. All three sizes are standard 120 × 200 cm – fitting most Flexa beds. Please note: Cold foam mattresses are lighter and easier to turn, pocket spring core mattresses are heavier but more durable.
Frequently asked questions about Flexa mattresses
Which mattress size fits my Flexa bed?
Most Flexa beds (e.g., the models in the Flexa Bed category) are designed for mattresses in 120 × 200 cm. Some beds offer adjustable sleeping surfaces – therefore, always measure the inner dimensions of the frame. A gap of a maximum of 2 cm between mattress and bed edge is acceptable. For toddler beds (e.g., cribs) there are also special sizes; check the compatibility in the product description.
How do bamboo and eucalyptus covers differ?
Bamboo fibers are particularly soft, absorbent, and antibacterial – ideal for allergy sufferers. Eucalyptus fibers have a cooling effect and wick away moisture faster. Both covers are removable and washable at 60 °C. For children who sweat heavily at night, we recommend the eucalyptus cover. In normally tempered rooms, the bamboo cover is completely sufficient.
Cold foam or pocket spring core – what is better for my child?
Cold foam mattresses ("Flexa Mattress Sleep") are lighter, point-elastic, and adapt well to light children. They are ideal for the first child's bed. Pocket spring core mattresses are firmer, more breathable, and support heavier children (from approx. 30 kg) better. An advantage of the pocket spring core variant: it retains its shape for years and is often usable on both sides with different firmness levels – so the mattress grows with the child.
Can I also use the mattress for a guest bed or teenager's room?
Yes, the 120 × 200 cm size is a standard size that fits many youth and guest beds. However, Flexa mattresses are specifically tailored to the ergonomic needs of children – for adults we recommend a different firmness. If you are looking for a mattress for a Flexa desk- or play area, pay attention to the overall height: Thinner models (approx. 10 cm) are also suitable as cushions for benches or reading nooks.

The right mattress is only one part of the children's room furnishings. In the FLEXA Shop you will find everything that completes the children's room. Particularly relevant for mattress buyers are the Flexa beds – because only on the right bed frame does the mattress develop its full effect. The beds are available in various designs, from classic wooden beds to bunk beds with integrated storage.
If you are redesigning the children's room, it is also worth taking a look at the Flexa chest of drawers – it offers space for clothes and accessories. For older children who already work at a desk, the category Flexa desk is interesting. All furniture is coordinated so that you can create a harmonious overall look. Consider before buying: Does your child need a growing bed? Then combine the mattress with an adjustable Flexa bed. Are you furnishing a sibling room? Then bunk beds or loft beds are the right choice – along with the matching mattress from this category.
