Whether it fits comes down to the measurements most people skip.

What decides itMattress thickness (on edge) vs. stair width, and mattress length vs. landing depth at turns
What to measureQueen: 60" × 80" × 10–14" thick. King: 76" × 80" × 10–14" thick

Real openings run about 1 to 2 inches under the labeled size, and a single inch can flip the result. Check your own measurements before you buy or move.

“Wish I'd used this before trying to force a fridge up the stairs.” — Lesson learned

Measure smart

What to measure.

Four numbers decide nearly every fit check. Get these right and the rest follows.

  1. 01Mattress type (foam, innerspring, or hybrid) — foam can bend to a ~24-inch radius for tight turns, while innerspring and hybrid are rigid and must be carried flat or on edge
  2. 02Mattress width vs. stair clear width — a king at 76 inches must go on edge (only 10–14 inches thick), while a twin at 38 inches may fit flat
  3. 03Landing depth at turns — a queen mattress on edge (80 inches tall) must pivot within the landing footprint without hitting the ceiling
  4. 04Mattress bag dimensions — a protective bag adds 1–2 inches per side and increases slipperiness, so factor bag bulk into every measurement

Don't make these

Common mistakes.

Most “it didn't fit” stories trace back to one of these oversights.

  1. ⚠Assuming a king mattress can be carried flat through a 36-inch stairway — at 76 inches wide it must go on edge, reducing the passing width to just 10–14 inches
  2. ⚠Not knowing your mattress bend radius — innerspring coils lock at roughly 36 inches of curve, while all-foam bends to 24 inches, making foam dramatically easier on tight landing turns
  3. ⚠Forgetting that a mattress on edge stands 76–80 inches tall and needs matching ceiling clearance at every soffit drop along the staircase
  4. ⚠Skipping the mattress bag — bare mattresses snag on banister brackets and collect wall dust, but a bag increases slipperiness so use moving straps to maintain grip

Frequently asked

Questions we keep getting.

  • Can I fold a foam mattress to fit up the stairs?

    Yes — all-foam and memory foam mattresses can be folded or rolled for short carries. Use ratchet straps to keep it compressed. This dramatically reduces the size for tight stairways. Do not leave it folded for more than a few hours. Innerspring mattresses cannot be folded.

    01
  • Which mattress sizes fit up standard stairs?

    Twin (38" wide) and full (54" wide) mattresses fit up most staircases when carried on edge — they're only 10–14" thick in that orientation. Queen (60") fits on edge but needs careful maneuvering at landings. King (76") is the hardest and often requires a foam fold or banister removal. See our furniture dimensions reference for exact measurements by size.

    02
  • How do I get a mattress around a stair landing turn?

    Stand the mattress on its long edge (it's only 10–14" thick that way). At the landing, pivot it around the inside corner. For foam mattresses, you can flex the mattress slightly around the turn. For innerspring, you may need to tilt at varying angles.

    03
  • Should I use a mattress bag when carrying it upstairs?

    A mattress bag protects against wall scrapes, dirt, and banister scratches, but it adds slipperiness. Use a bag for protection, but grip the mattress through the bag or use moving straps. Never slide a bagged mattress on stairs — it can slip and cause injury.
