One of the biggest pluses about kitchen islands is that most of them contain extra storage space for all of the paraphernalia that is so necessary in a kitchen today. A kitchen island cabinet can be just the solution to the problem of "Where am I going to put that?"
In addition to seating 4 (or more), islands today are used to house "luxury" appliances that do not fit in the cabinet structure like a second microwave, second oven, wine refrigerator or even another cooktop. Islands many times are fully wired for electricity and have plumbing for a second sink. The base of an island can be used as a wine rack. The possibilities are almost endless.
Safety First! You are better off without it if you are using up all the free space in the room. Your kitchen should be spacious and you should never feel restricted in your movement - in fact it can be dangerous if you are. Yes, a kitchen island is good to have, but not if your safety and freedom of movement are compromised to accommodate it.
You may only have a limited space and you think that seating will only make your kitchen look crowded. However, it does not mean that you can't have seating. For a room with limited space, you can use smaller stools. To save space, you can also choose chairs that you can store in a closet when you do not need them.
