Floating shelves look fragile to the naked eye because of the way they sit on the wall. All the workings of the brackets are hidden so it seems as though they are floating there on the wall. In reality they are usually much stronger than other types of shelves which are supported with traditional brackets and screws.
Home interior decorating covers many aspects of the tasks. A lot depends on how much time you have to spare and what your budget is - whether you just want to spruce up a room or give it a whole new look. It is surprising for instance what new bath mats and towels do for a bathroom. Try sprucing up your room with some new cushions and perhaps a mirror or two. Move the furniture around and add feature wall paper on one wall - make sure that it tones in with the existing color scheme and you will be surprised how much style this can give to a room.
