Here are some tips when buying a sofa bed:
1. Sit on both sides of the sofa. Is it stable and sturdy? Are the joints secure? Lie down on it to know it the comfort goes both ways. Also make sure that it converts to a bed in a smooth and easy way, and vice versa. Ask for large-diameter steel tubing to be attached to the bed’s skeleton for added durability.
2. Ask yourself how big a space will you be allotting for it. If the space is too small, a sofa that folds out into a queen or kind sized bed are absolutely out of the question. Also, consider the number of people who will be sleeping on it.
3. Does the headrest lock in place easily? For purposes of reading or watching TV.
4. Ask for a couple of days to actually test it at your home.
