Enter your mattress size and window measurements — the app checks opening size, flex options, and hoisting feasibility.
Mattresses fit through windows better than most furniture. On edge, a mattress is only 10–14" thick. Foam mattresses can be rolled or folded to fit through openings as small as 24" × 36". Remove the window sash for maximum opening size.
Mattress thickness (on edge, 10–14") vs. window opening width, and mattress length vs. opening height
Item: Queen: 60" × 80" × 10–14" thick. King: 76" × 80" × 10–14" thick
Space: Standard window (sash removed): 24–36" W × 36–60" H opening
Tip: Remove the sash and stand the mattress on edge — at only 10–14" thick, it fits through most window openings easily. Roll foam mattresses for extra-small windows.

Yes — all-foam and memory foam mattresses can be folded, rolled, or bent to fit through surprisingly small openings. A queen mattress rolled tightly (with ratchet straps) can fit through an opening as small as 24" × 36". Innerspring and hybrid mattresses cannot be bent and must fit through the opening as-is.
A twin mattress (38" × 75" × 10–14") on edge fits through most windows with the sash removed (36–60" opening). A queen (60" wide) is too wide for most windows laid flat, but on edge (10–14" thick) it fits through any opening over 14" wide — the 80" length must fit the height. Foam mattresses of any size can be rolled.
Remove the window sash. Place moving blankets over the sill. Stand the mattress on its long edge outside the window and feed it through lengthwise. For foam mattresses, roll or fold with ratchet straps before pushing through. Two people — one inside, one outside — make this straightforward.
For upper floors, hire professionals. A mattress acts as a sail in even light wind, making it extremely dangerous to hoist without rigging equipment. Professional furniture hoisting costs $300–$600 for a mattress. For first-floor windows, DIY hand-loading is safe with two people.
Removing a window sash adds 2–4 inches of clear opening. Here's how to safely remove different window types for furniture delivery.
Not all windows are big enough for furniture delivery. Here's how different window types compare — and which ones give you enough clearance.
Window delivery isn't a last resort — in some cities it's standard practice. Here's when removing a window is the best (or only) option for getting furniture inside.
