The Adelaide upholstered dining chair offers a designer silhouette and features an elegant waterfall skirt and 18 x12 inch kidney pillow. The casters create ease of movment. The standard casters on all Lexington Home Brands upholstered chairs are designed for use on carpeted, porcelain, ceramic or stone surfaces. Most hardwood and vinyl floors have a softer surface, which may cause casters to leave tracking marks. In cases where the chairs are used directly on hardwood flooring, engineered flooring or vinyl surfaces, the standard casters should be replaced with hardwood-safe casters.
