• The humidity produced by any type of liquid in the mattress is not a manufacturing problem, but a maintenance problem due to not protecting it with a suitable waterproof cover.
• Mattresses are products that are developed to support the weight of one or two people lying down. It is not recommended to jump on them, because the same weight is concentrated in a smaller area. This can cause deformities in it.
• If the mattress support is not in adequate condition, it will affect the mattress, creating deformations that will not be accepted as a manufacturing incident of the mattress.
• Double-sided mattresses should be flipped at least once a month for the first six months and rotated at the same time. Then repeat every 3 months. The one-sided ones will only have to rotate it. The durability of the mattress will be greater.
• Latex mattresses should always be supported on a slatted base so that the mattress breathes. If used on an upholstered base, moisture and mold problems may arise.
