A loft bed is a type of elevated bed that creates extra space underneath for various uses. It typically features a sturdy frame that raises the mattress off the ground, allowing for storage, a desk, or a seating area below. Loft beds are popular in small living spaces, such as dorm rooms or studio apartments, where maximizing floor space is essential. These beds come in various styles and sizes, accommodating different mattress dimensions, including twin, full, and queen. Many loft beds are designed with safety features like guardrails and ladders, making them suitable for both children and adults.
