Two modules: one arm module and one chaise. This is the simplest of the four layouts, with an extended lounging side. The linked product is the left-chaise configuration. Check its orientation against your doorway, walking route and room plan before ordering.

Three modules: one arm module, one chaise and one separate ottoman. Compared with THE L, the separate ottoman adds another piece to position around the seating area. Use a floor plan to check clearance around the ottoman as well as the main sofa.

Four modules: one arm module, one center module, one chaise and one separate ottoman. The added center module distinguishes this arrangement from THE U. Compare the full assembled footprint on the product page with your available wall length and circulation space.

Five modules: two arm modules, one center module and two separate ottomans. This is the symmetric arrangement in this four-layout guide. Plan space for both ottomans and keep the route through the room clear; check current dimensions and options on the linked product page.

Before selecting a layout: measure the available floor area; mark the sofa and ottoman footprints on a simple room plan; check the chosen chaise orientation; leave a clear walking route; and compare packaged dimensions with doorways, stair turns and any elevator. Confirm current delivery availability, unpacking instructions, dimensions and upholstery options on ULTIONE’s official website. This checklist is a planning aid, not a promise that any layout will fit every room.
