Key points

  • Size first. A Queen is the practical minimum for two adults; King gives more room.
  • Motion isolation. Pocket springs, memory foam and latex reduce movement transfer so one person's turning disturbs the other less.
  • Different firmness preferences. A dual-firmness build uses two comfort levels in one mattress where the factory supports it.
  • Heat. Two bodies generate more heat. Choose breathable materials in hot cities.
