Spiderman Kids Sleepover Sofa (#1850) The sleepover is a real piece of furniture unlike many of the foam flip chairs and sofas that are sold in the assorted licenses at the mass retailers. Each piece contains a mixed hardwood frame, and is upholstered using polyurethane foam pad filling. When in the sofa position it features a slightly curved backrest and stylish curved armrests that are padded in front and extend out at the top from the floor. Fronts of the armrest are flat. When you pull out the backrest, it becomes a sleepover and a child can either put a sleeping bag on top of the mattress portion, or it can be used with a sheet and blanket. It is also a popular playtime item. Age range on this item can start from 2 and depending upon the size of the child, it can be used until 8. There are cushion glides on the bottom of each piece to protect the fabric and avoid tearing.
