Details before you move
No. The Devyn arrives as separate pieces — an arm sofa, an open-end chaise, and an ottoman. The dimension that decides whether it fits is the largest single piece, not the 120-inch assembled footprint. Costco does not publish per-piece carton sizes, so measure your largest piece on delivery.
The complete assembled sectional measures about 120 inches long by 81.5 inches deep by 36 inches high, with a total weight near 289 lb across all pieces.
Costco publishes only the assembled overall footprint for this item, so that is the conservative starting point shown here. Because each piece is smaller, the real-world fit is usually easier — enter the depth and height of your largest single piece into the checker for an accurate answer.
These are Costco's published overall figures for item #100809290 captured in mid-2026, drawn from a search-surfaced spec snippet rather than a verified live page. Treat them as a starting estimate, measure your actual pieces and doorway, and confirm with the live checker.
