Full review of the IKEA FRIHETEN Sofa Bed is available here:
The IKEA FRIHETEN is a sofa lounger that has a built in ottoman, storage under the lounge seat and can be used as a guest bed.
Most of the components of the IKEA FRIHETEN come assembled out of the box so the full assembly of the sofa is fairly straight forward. This video demonstrates the overall process.
If you have any questions about the assembly or the product itself feel free to ask them in the comments below.
