Open Export ToolThe KAIERTE Tri-Lobed Modular Upholstered Lounge Ottoman, model OTM-TRI-1800, is a purpose-built soft seating solution categorized as an upholstered lounge ottoman and soft seating bench, distinguished by its symmetrical three-lobed form arranged with 120-degree separation between each rounded seating section. Each lobe connects via a curved central web, with bright gold recessed cutouts along each lobe side creating bold two-tone contrast against the matte purple woven polyester covering seat tops and outer panels; the full perimeter features smoothly rounded, padded edges with no exposed hard corners, and the concave inner curves between lobes allow users to sit close when gathering toward the central open zone. Built for high-traffic use, the unit uses an internal birch plywood support frame, paired with high-resilience polyurethane seat foam for firm, shape-retaining support, and thinner polyurethane foam under side upholstery for soft edge profiles. Reinforced stitched seams connect purple and gold fabric sections, with hidden turned-edge finishing to prevent fraying. A black non-slip non-woven base layer protects flooring and prevents unintended sliding, with optional self-adhesive felt glides available to prevent scuffs on polished wood or tile. The tight-weave polyester upholstery supports spot cleaning with commercial fabric cleaner, with abrasion resistance, colorfastness, and anti-tip stability aligned to standard commercial soft seating requirements. Functionally, the ottoman seats three adult users across its dedicated lobes, with the central section rated for partial seating or temporary placement of items such as laptops, drinks, or reading materials. It is a free-standing, non-mobile unit that requires no floor anchoring, and is compatible with same-height matching curved soft seating modules to build extended seating clusters. Custom commercial fabric colorways are available for large orders to align with interior design schemes. This piece suits a wide range of commercial and residential-adjacent spaces, including office open plan breakout areas, school and library common zones, creative agency and hospitality reception areas, children’s play and daycare spaces, trade show and pop-up event seating, and retail customer waiting zones such as apparel boutiques and beauty salons. For procurement, note the unit ships fully assembled in a single package with minimal on-site placement time, with optimized loading quantities available for standard freight containers. Buyers should confirm specific fabric fire ratings, exact frame material specifications, and final product dimensions with the supplier prior to final order placement, and may select matching cylindrical ottomans and low coffee tables to build coordinated lounge layouts.
