Bad sleep affects development, focus, and mood.

Is Your Child Tossing and Turning at Night?

Kids need consistent support to sleep well – yet many mattresses are too soft, too hard, or lack airflow.

BALANCE combines a breathable design with dynamic support to ensure peaceful, uninterrupted sleep.

Five layers of adaptive comfort and support

What’s Inside BALANCE? A Smart, Supportive Sleep System

BALANCE is engineered for comfort, support, and airflow from top to bottom:

  1. Soft Cotton Cover - Oeko-Tex® certified and machine washable for hygienic comfort

  2. Memory Foam Layer (2 cm) - Adapts gently to older children’s shape and movements

  3. Pocket Spring Core - Individual springs offer precise support and minimize motion transfer

  4. Supportive HR Foam Layer (4 cm) - Firm, stabilizing support for younger children

  5. Reinforced Base Layer - Maintains the mattress’s structure and enhances durability

Reversible Design: Flip between soft and firm sides to suit your child's age and comfort preference.

Adapts to your child's growing body

Smart Comfort for All Childhood Stages

BALANCE grows with your child. The soft memory foam side provides gentle relief for older kids, while the firm foam side ensures healthy support for younger ones.

The Oeko-Tex® certified cover is removable and washable, maintaining freshness and hygiene. One mattress, two comfort levels – for years of safe, restful sleep.

Risk-free sleep trial. Long-lasting support.

100 Nights to Try – 10 Years to Enjoy

Try BALANCE for 100 nights. If it’s not the perfect fit, return it hassle-free.

Every BALANCE mattress is also backed by a 10-year warranty, ensuring comfort and quality that lasts.

Virkelig lækker madras

God støtte, blødt betræk og masser af plads. Den er tung at flytte rundt på, men det forventede vi også i denne størrelse.

Muy buena compra

El colchón es cómodo y firme. Nos gusta mucho poder darle la vuelta cuando nuestro hijo prefiera una sensación más suave.

Ingen grund til at købe en ny senere

Det reversible design var afgørende for os. Når vores datter ønsker en blødere madras, vender vi den bare. Virkelig gennemtænkt.

Una compra para muchos años

Se nota resistente y cómodo. Elegimos el lado más suave, pero nos tranquiliza saber que podemos cambiarlo si las preferencias cambian.

Heel tevreden

De stevige kant geeft goede ondersteuning en het matras voelt degelijk aan. Fijn dat we het later kunnen omdraaien voor een zachter gevoel.

Très confortable

Notre fille dort très bien depuis que nous avons installé ce matelas. Le côté réversible est une excellente idée pour accompagner sa croissance.

Très bon matelas

Le matelas est confortable, bien fini et suffisamment ferme. Le système réversible nous permettra de l'adapter sans devoir en acheter un nouveau.

Passer perfekt til FLEXA-sengen

Madrassen passer præcist i sengen og giver god støtte. Vi startede med den faste side, og vores barn virker meget tilfreds.

Matelas très confortable

Matelas très confortable, housse en coton lavable très pratique. Notre fils est ravi de ce nouveau matelas.

Vendbarheden giver mening

Det er smart, at man ikke skal vælge én fasthed for altid. Vi prøvede begge sider og endte med den faste, men det er godt at have muligheden.

Gute Qualität

Die Matratze wirkt hochwertig und der Bezug fühlt sich angenehm an. Sie ist etwas schwerer als erwartet, aber dafür sehr stabil.

S
Søren B.
Behagelig og praktisk

Betrækket er blødt, og det er en stor fordel, at det kan tages af. Madrassen er lidt tung at vende alene, men kvaliteten føles rigtig god.

Sehr gute Entscheidung

Die breite Matratze ist bequem und bietet viel Platz. Besonders gut gefällt uns, dass man zwischen einer festeren und einer weicheren Seite wählen kann.

Sehr bequem

Unser Sohn schläft sehr gut darauf. Die feste Seite bietet eine angenehme Unterstützung, und später können wir die Matratze einfach wenden.

Super komfort

Vores teenager er meget glad for madrassen. Den brede størrelse og den blødere side giver næsten følelsen af en voksenseng.

Føles som en madras der holder

Den virker virkelig solid og støttende. Jeg kan ærligt talt ikke forestille mig, at vi får behov for at udskifte den foreløbig.

Perfect for a growing child

The reversible design makes so much sense. We can change the comfort level without buying another mattress, and the 140 cm width gives plenty of room.

A mattress that can adapt

We are using the firmer side now and plan to turn it over as our daughter grows. It feels like we will not need to replace it for a very long time.

God investering

Vi ville gerne have en madras, der kunne følge med i mange år. Den virker både robust og komfortabel, og vi tror ikke, vi kommer til at udskifte den længe.

M

Meget tilfredse

Meget tilfredse. God komfort og flot kvalitet.

C

Smart at den kan vendes

Vi købte den især på grund af de to sider. Den faste side passer perfekt nu, og senere kan vi skifte til den blødere side i stedet for at købe en ny madras.

Feels built to last

This mattress feels substantial and very well made. We chose the softer side for our teenager, and I genuinely cannot see us replacing it for years.

Excellent support

Our son moved from a thinner mattress to this one and the difference was noticeable immediately. It feels supportive and comfortable without being too soft.

God støtte fra første nat

Madrassen føles fast uden at være hård. Vores datter sov godt på den allerede den første nat, og betrækket virker lækkert og behageligt.

Perfect for my daughter, practical and long-lasting

I’m really happy with the Flexa mattress for my daughter! The double-sided design is such a great idea. One side is firmer and the other softer, so it adapts as she grows. I also love that the cover is removable and washable, which is a huge plus with young children. She’s been sleeping so well since we got it, peaceful nights all around! Thanks Flexa!

Fantastisk til den brede seng

Den brede madras giver virkelig god plads, og begge sider føles behagelige på hver sin måde. Vi bruger den faste side nu og gemmer den blødere til senere.

M
Maria S.
Virkelig god madras

Vores søn foretrækker den faste side lige nu, men det er rart at vide, at vi kan vende madrassen, når hans behov ændrer sig. Den føles som et køb, vi kan have glæde af i mange år.
