Of course, you can always buy a cot mattress at a furniture centre or a shop with accessories for babies. It^s much more convenient and less time-consuming. But unfortunately, it"s more expensive at the same time. If you really want to save money, here is my advice for you. Visit a large shopping centre that specialises in selling reasonably priced, quality furniture. I don"t have to give you examples, I suppose. There are surely some furniture shop chains in your area. Go straight to the unseasoned wood furniture section. Look for a simple cot, and if you can"t find anything, go to the baby furniture section. As soon as you have found the right cot, get some white paint. It will probably be available at the same shop. Some parents might be afraid that pain may contain dangerous substances. Let"s take lead, for example. In the past there was a tendency to add lead to paint, but now it"s very unlikely. Read the label if you are still not sure. Then you just take a brush and pain the bed! If you don"t feel like doing this, but you still want to get a bed cheap, order a cot mattress on the website of a trusted, recommended manufacturer of specialist baby furniture. Don"t buy poor quality stuff at popular shopping centres!
