Choice of a mattress for the child

[Lyudmila]

The dear doctor! In my daughter (10 years) have found out disturbance of a posture with initial development of a scoliosis. What mattress to choose for its or her bed? Simply enough rigid or it is necessary orthopedic? Though orthopedic mattresses too happen different rigidity.
Prompt, please!

About mattresses I shall not prompt.
And here with a scoliosis I advise to address to the children's orthopedist (internally)

[The first doctor]

Always more usefully a rigid mattress.
