Mattress toppers

A mattress topper is like a thinner version of a mattress, designed to elevate sleep comfort to a higher level. It adapts to your body and adjusts the properties of your sleeping surface by softening, firming, compensating for uneven areas, or reducing the gap sensation on a sofa bed.

If the main mattress is too firm, choose a topper at least 5 cm thick.

A viscoelastic memospace-5, memospace-7 topper is the best option — it softens the surface and adapts to the body: https://www.lonas.ee/en/272-soft-mattress-toppers/

Alternatives: a soft HR foam topper — it adds elasticity and comfort.

A mattress topper cannot fully replace a mattress, but it can improve its properties or temporarily compensate for an old or overly firm base. A topper is a thinner layer, a few centimeters thick, placed on top of the main mattress.
