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

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!
