A mattress topper is a removable 5 cm to 8 cm thick comfort layer placed on top of a mattress to adjust firmness, relieve pressure, and improve sleep quality. Popular options include memory foam, high-density foam, and lightweight fiber fillings.
Firmness Fix: Use a soft memory foam topper if your current mattress is too hard.
Attachment: Most foam and fiber toppers use corner elastic bands to stop slipping.
Limitations: A topper adds comfort but cannot fix a deeply sagging or completely broken mattre
