Twilight Sleep Sofa is ok — the seat is comfy and firm but the lack of arms and the low bolster is not ideal for long-term lounging. But as an occasional sleeper, this design gets rave reviews as it is surprisingly comfortable. With the options of using Twilight as a sofa, twin bed or queen-ish bed (a bit larger than a queen and a tad smaller than a king), versatility is key in this design. And while it may not be the best primary sofa, Twilight is a great solution for a secondary seating arrangement that doubles as a sleeping area for guests — especially in an office, nursery or other small room. The simple and straightforward design make the transition process fairly intuitive. Small wheels on the rear legs make it fairly easy to move around. Once one is comfortable with moving the bolster into one of its 3 positions, the change from sofa to bed is as easy as moving and positioning a twin mattress. It's not nearly as smooth as some of the high-design beds like the Mostra from Ligne Roset, but good for occasional use. Delightfully, the sofa base and cushion line up precisely for a tight fit and minimal gap. Currently Twilight Sleep Sofa is available in 2 frame options, Black ($1,880) and Aluminum ($1,680) and there are 5 choices of slipcovers: Autumn (orange), Dark Grey, Grass, Light Blue (aluminum frame) and Black & White Herringbone (black frame). The slipcovers are removable and should be dry cleaned but replacement slipcovers can also be purchased from DWR for $500 - $700 (Black & White Herringbone).
