  • Sound Absorption Rating: Look for blankets that list decibel reduction. Higher ratings mean quieter rooms.
  • Thermal Insulation Value: Choose blankets with thick padding or thermal lining. They trap warm air and stop cold drafts.
  • Durability and Build: Look for reinforced stitching and strong fabric. A sturdy blanket lasts for years.
  • Cleaning and Maintenance: Pick a blanket that is washable or wipe‑clean. Simple care keeps it working well.
