Trundle mattresses are perfect for children’s bedrooms and guest bedrooms. When your little ones have a sleepover, a trundle mattress is ideal. You effortlessly store it under a bed, out of sight, and bring it out for guests when needed! If your child’s bedroom has limited space, a trundle bed mattress is the perfect way to utilise every inch of the room. It’s also the ideal solution for a guest bedroom. If you only have enough space for a single, it’s worth investing in a trundle bed.
