Need more room than a single mattress but don’t have space for a double? A king single mattress is the perfect in-between — offering extra length and width for growing teens, taller sleepers, and guest rooms where comfort matters.
At Rivercity House & Home Co, we offer a range of king single mattresses designed for support, durability and a great night’s sleep. Choose from pocket spring, memory foam, hybrid and gel-infused styles in comfort levels from medium to extra firm. Whether you're furnishing a teenager’s bedroom or upgrading a guest bed, we’ve got a sleep solution that fits.
All mattresses come vacuum-sealed for fast, contact-free delivery and easy setup.
