Generally, loft sofas are designed to have smaller dimensions, as they are designed with lofts specifically in mind.
Loft spaces are generally fairly small, and they often contain limited overhead space; choosing the best loft sofas will therefore often boil down to taking careful measurements and finding a sofa or sofas that will fit in that limited space. It is a good idea to take other factors into account, therefore, to narrow down the search. Your budget, for example, will have a significant impact on your options, as will the aesthetics of loft sofas you are considering.
Determine ahead of time how the loft space will be used in order to figure out which loft sofas will be most appropriate for the space.
If, for example, children will often use the space, it will be important to consider loft sofas that feature sturdy frames and upholstery that can be cleaned easily. Sometimes the upholstery is stain resistant, which is a great choice for any room in which children will be playing frequently. If, however, the loft space is intended mostly for adult use and for entertaining, a sofa with higher end upholstery such as leather may be appropriate.
The materials used to make loft sofas can vary significantly, and the best choice will often boil down to a combination of functionality and your aesthetic preferences. Try to choose upholstery and other materials that are durable and attractive, and make sure the sofa will match the overall decor of the room in which it will be placed.
Many loft sofas sit closer to the ground because loft spaces often have lower overhead clearance. Some loft sofa models will feature fold-out mattresses that will allow you to convert the sofa into a sleeping surface. If you are considering such a design, be sure to choose loft sofas that are lightweight, as you will need to carry the unit all the way up to the loft space from the ground floor, which can be difficult in the best of situations.
