staircase with a 90-degree landing turn
Tight Fit- the ~96-inch box length is hard to pivot at a mid-flight landing
- a straight run of stairs is far more forgiving than an L-shaped one

The item
Model 103.551.18
PAX is IKEA's full-height modular wardrobe system. The frame ships as one long, flat carton, roughly 96 by 24 by 3 inches at about 105 pounds, with doors and interior fittings boxed separately. The eight-foot box length is the hard part: thin and not very wide, but very long to pivot on stairs and around corners.

Details before you move
The single tall PAX frame (100×58×236 cm assembled) ships flat in one carton about 243 by 61 by 8 cm (roughly 96 by 24 by 3 inches), weighing about 47.6 kg (105 lb). Doors and interior fittings are separate articles in their own packaging.
The box is only about 3 inches thick, so width and thickness rarely block a doorway. The problem is its 8-foot length — pivoting an 8-foot rigid box around a stair landing or tight turn is where most people get stuck.
At about 105 lb the weight is manageable for two people, but the length makes balance awkward on an incline. On a turning staircase, measure the diagonal clearance at the landing before committing — the checker above can model your stair geometry.
These are IKEA's published figures for the white 100×58×236 cm frame, captured in mid-2026; carton sizes can shift slightly between runs. Measure your stairwell and the box you receive, and rely on the live checker for your exact situation.
