If you have the room for a change table then I think its money well spent... it really does save your back IMO! I used a change table for DD until she was about 2.5yrs & DS until he was about 1.5yrs (had to sell DS's due to going through a divorce & needing to stay in a tiny flat with no room for a change table, otherwise I would have continued to use it)

If you dont have room then the bed or the floor works fine
