The mattress topper is placed on top of the main mattress in order to upgrade the behavior of the mattress and improve its feel by providing comfort and softness for better sleep quality. The main advantages are that it extends the life of the mattress by protecting it from wear and tear and that it absorbs more shocks, while contributing to changing the firmness of the mattress to better suit your needs. As for its care, after consulting the manufacturer's instructions, dry cleaning is recommended on an annual basis and weekly airing.
