Q: “How do I know if my crib uses a hook type or a bolt type mattress spring frame?
A: Check on the headboard or footboard for height adjustment brackets. If the brackets have holes only, a bolt in type spring was used originally, if the brackets have hooks or ‘ears” then a hook type spring frame was used originally. If you are not sure which type of mattress spring your crib requires please call Products America for direct assistance at
