This Molton bed liner of Bierbaum is in my opinion a must-have in a baby bed, since thus can prevent any contamination which would otherwise be transferred to the mattress. Under a normal jersey fitted sheets, can this Betteinlage conceal well and fulfills its purpose. The bed liner is coated on both sides with Molton, boil-proof (up to 95 ° washable) and meets the Öko-Tex standards. The important thing is just that it is waterproof, yet comfortably soft. The price is in relation to the respective selected size in my eyes quite appropriate, because I've seen more expensive models.
