A king size body pillow is longer and thicker than a standard one, usually around 20 by 54 inches or more, which gives taller people and those who like to hug a pillow more to wrap around. The best ones have a dense but soft fill, a washable cover and a length that suits your height. Check the bed space first, since they take up room.

What makes it king size

Body pillows come in many lengths, and there is no strict standard. Most standard body pillows run about 20 by 48 inches; the king size designation usually means closer to 54 inches or longer, and often a fuller circumference. That extra length lets taller sleepers extend their legs along it, supports pregnant sleepers who like wrapping around the pillow and gives side sleepers more room for arms and knees.

Down alternative cluster Soft, plush Light Moderate Often machine wash
Shredded memory foam Medium to firm Heavier Can warm Spot clean fill, wash cover
Memory foam slab Firm Heavy Can warm Spot clean
Feather or down Soft Light Cool Careful wash

Choosing the right dimensions

  • Under 5 foot 6: a standard length is probably enough.
  • Taller sleepers: a king size lets you extend your legs along the pillow.
  • Shared beds: measure your side of the mattress.
  • Pregnancy: longer pillows support both knees and the belly.

Shop with a purpose

Begin with a king size body pillow. If you want a cover set, add a body pillow cover with zipper. For firmer support, look for a long memory foam body pillow.

Who benefits

Side sleepers who want hip alignment, hugging sleepers, expectant parents and people who like to prop themselves for reading. Back and stomach sleepers rarely need one. Couples sharing a queen bed may find a king size body pillow crowds the middle.

Getting the most out of it

Hug it with your arm, put it between the knees and rest your top leg along its length. Keep your head on a separate pillow. A pillow that sags in the middle may need a firmer fill or a re-fluff before bed.

Care and maintenance

Because of its size, a king body pillow can be hard to fit in a home washer; check the label and consider a laundromat’s large machine. A cover with a zipper simplifies washing. Fluff the pillow each morning and air it out weekly. Replace when it loses support.

Common mistakes

  • Buying without measuring the bed.
  • Choosing a thin cover that wears out at the ends.
  • Forgetting a spare cover.
  • Using the pillow in place of a pillow for the head.
