This loft bed is made of pine and MDF, the solid wood slats blend naturally with the already sturdy frame to give extra support to the floor, which can withstand up to 350 lbs to ensure stability and durability for years of noiseless, vibration-free, and long-lasting use.The upper bunk is fitted with full-length guardrails that provide extra protection against falls, while a staircase with handrails provides easy and safe access to the upper bunk, making it easy to climb up and down, providing your child with a comfortable night's sleep, and fully ensuring your child's safety.There are three storage shelves under the bed for books, toys and other household items, and the attached staircase can be used not only as a staircase but also as a storage space, providing spacious storage while maximising space savings.
