Enter your staircase measurements to see if a double bed will navigate the turns — frame, mattress, and headboard.
Whether it fits depends on measurements most people get wrong.
Mattress width (54") vs. stair width and landing depth
Item: Double/full mattress: 54" W × 75" L × 10–14" thick. Bed frame: varies by design
Space: Standard residential staircase: 36" wide, 80" ceiling clearance
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

Moving a 200-pound dresser or appliance upstairs without injury requires the right technique and equipment. Here's how professionals do it safely.
Most people measure stair width and call it done. The landing, ceiling height, and turning angle are where furniture actually gets stuck.
Always. Separate the headboard, footboard, side rails, and slats. Carry each piece individually. The mattress goes separately. This converts one impossible move into several easy ones.
A double (full) mattress is 54" × 75". On its side, it needs only 54 inches of clear height and 10–14 inches of width (its thickness). It fits through most stairways — the landing turn is usually the only constraint.
Traditional box springs are rigid 54" × 75" rectangles. If your stairs have tight turns, switch to a split box spring, bunkie board, or platform base with slats — these fold or separate for easy transport.
