The mattress topper is placed on top of the main mattress to enhance the performance of the mattress and improve its feel by offering comfort and softness for better sleep quality. Key advantages include that it extends the life of the mattress by protecting it from wear and tear and that it absorbs more shocks, while it helps change the firmness of the mattress to better suit your needs. Regarding its care, after consulting the manufacturer's instructions, it is recommended to wash the cover at 30°C.
