The queen-sized Killian sofa bed is designed to provide an elegant, compact and durable design that can be used as a comfortable everyday sofa and extra bed. In sofa position Killian holds an even, supportive foam seat cushion and a large Dual mattress with large, yet rounded armrests, altogether providing a good lounging comfort and lovely 2-seater sofa. In bed position, Killian features our comfortable mattress having two comforts in one – a soft side with memory foam and a firmer side with high resilient foam – enabling the opportunity to decide between two comforts. Further, the mattress cover is removable and can be machine washed at hot/140F.
