Step 1
Decide if you want a hardside or softside waterbed. Hardside beds are mattresses filled with water that sit on top of a wooden frame. Softside beds are water-filled mattresses that are inside a foam frame encased in vinyl.
-
Step 2
Measure your room. While softside beds look like regular beds and come in conventional sizes, hardside beds have rigid external frames, which make them a more unconventional size, and they sometimes come in slightly oval shapes. Account for extra space if you want to add a headboard to your waterbed.

Step 3
Determine how soft or firm you want your waterbed to be. If you want more cushioning, add a pillow top. You can also add memory foam on top of your bed so it molds to the shape of your body.

Step 4
Shop around. Prices for waterbeds range significantly. Comparison shop at websites such as eWaterbedStore.com and Waterbed.com.
