[TWIN BED CONNECTOR STRAP] Comes with a 980cm long bed strap to hold the bed rails in place so they don't slip or move apart while you sleep. The bed bridge spacefiller measures 200cm long by 20cm wide, larger than other standard bed bridges. It comes with two handy ribbons on the edge on each side to help keep the bed bridge in place so it doesn't fall into the bed gap. [BED BRIDGE INTEGRATION] You can join two bed combinations (Twin, Twin XL, Full, Full XL, Queen) to create a larger bed with the connector and bed filler kit. No gaps, bumps, or bulges. Perfect for family rooms, bedrooms, and vacation rentals. [PREMIUM & BREATHABLE] The twin-to-king bed connecting kit includes a cotton foam cushion, designed with plenty of space for good ventilation. It's stitched all around the edge, so there won't be any issues with fraying. [SET UP IN 2 MINUTES] Push your twin beds together; place the filling bridge over the bed meeting area; buckle the top and bottom straps along the side; pull the free end of the adjustable straps to tighten.
