The Olympic Twin XL Over Twin XL Bunk Bed With Stairs puts shaky, squeaky bunks to shame with adult-grade strength. Built from high-grade plywood, this heavy-duty bunk bed for adults laughs in the face of cracks, splits, and squeaks. Plywood’s layered construction means it’s even tougher and more impact-resistant than solid wood, and that’s why this is our strongest bunk bed yet. Specifically engineered with adult sleepers in mind, each bunk is weight-tested to hold an impressive 800 lbs. per sleep surface. The twin XL length gives taller sleepers space to actually stretch out, while the 47.25 inches of space between bunks allows plenty of space to sit up without an accidental head bump. Plus, this bunk bed with stairs for adults isn’t just strong—it’s safe, too. With 13-inch guardrails, an easy-to-climb staircase, and built-in shelving, we’ve thought of every detail to keep you and your guests sleeping safe and sound night after night.
