The item
Costco Manhattan Leather Sectional
The Manhattan is an HTL leather sectional sold at Costco, roughly 107 by 85 by 35 inches assembled and about 230 pounds across all sections. Because the leather is stretched over a firm frame, the pieces will not compress for a tight turn the way a soft fabric sofa can. Plan around the largest single section, which arrives and moves on its own.

Frequently Asked Questions
- 01
Does the Manhattan sectional come up the stairs as one piece?
No. It is a multi-piece sectional delivered as separate sections. On stairs the limiting object is the largest single piece, not the 107-inch assembled width. Carton sizes are not published, so measure each piece when it arrives.
- 02
What are the assembled dimensions?
The complete sectional measures roughly 107 inches wide by 85 inches deep by 35 inches high, weighing about 230 lb in total across all pieces.
- 03
Why are leather sectionals harder on stairs?
Leather upholstery over a firm frame does not flex, so unlike a soft fabric piece you cannot squeeze it through a tight turn. The rigid largest piece must physically clear the stairwell and any landing pivot.
- 04
How reliable are these measurements?
The figures here are for Costco item #678453 captured in mid-2026 from a third-party Costco-spec aggregator citing the in-warehouse spec card — Costco's own live page was not reachable. Treat them as an estimate, measure your actual pieces and stairwell, and confirm with the live checker.
