SIEGEN Sofa, Gray, 87"L X 35"W X 33"H (SEAT HT: 22", SEAT DP: 24"), 150lbs. The angled legs and straight arms are a dead giveaway for this sofa's mid-century inspired design. Look closely and you'll notice a same color welt trim that blends beautifully with the contrast stitching. Most notable of all are the back cushions adorned with biscuit-style tufting. Plush cushion seats are cradled by the sloping base, which curves up on the sides to form a simple silhouette that is as striking as it is basic.
