Enter your mattress size and staircase measurements to plan the move — landings, ceiling clearance, and turns included.
Whether it fits depends on measurements most people get wrong.
Mattress thickness (on edge) vs. stair width, and mattress length vs. landing depth at turns
Item: Queen: 60" × 80" × 10–14" thick. King: 76" × 80" × 10–14" thick
Space: Standard residential staircase: 36" wide, 80" ceiling clearance, 36" landing depth minimum
Actual clear openings are usually 1–2″ smaller than the labeled size.
Your exact dimensions probably aren't "standard." Small measurement errors cause big problems — 1 inch can be the difference between fitting and getting stuck.
Verdicts are calculated by comparing all 6 item orientations against the space dimensions using verified building code standards. See our methodology

“Wish I'd used this before trying to force a fridge up the stairs.” — Lesson learned
Measurements verified by the ItemFits engineering team · Based on IRC R311.7, IBC Chapter 10 · Our methodology
Standard sizes say it works — but your measurements are what matter.
Most people measure stair width and call it done. The landing, ceiling height, and turning angle are where furniture actually gets stuck.
Not every stair move needs professionals. But some absolutely do. Here's the line between "you can handle this" and "call the pros."
Most people measure width and call it done. Moving requires 6 measurements per item — plus path measurements. Here's the complete measurement protocol.

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.
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.
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.
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.
