Have a wood framed waterbed. Wander if a regular mattress like a Sealy, Serta would fit it? We are answering the the question:
Are Standard Mattress Sizes The Same As Waterbed Sizes?
No they are not. Wood framed waterbed mattresses and standard size mattresses are not the same size. However below are the 3 standard wood frame waterbed sizes. Along with them are the common correlating standard mattress sizes people often think will fit. As you will clearly see regular mattresses are not a good fit. Below the measurement I have provided a link that will solve such a dilemma.
- Super Single waterbed cavity is 48 by 84 where twin size standard mattresses are 38 by 75 and full size standard mattresses are 54 by 75.
- California Queen waterbed cavity is 60 by 84 and a standard queen mattress is 60 by 80
- California King waterbed cavity is 72 by 84 and standard king mattresses measure 76 by 80
See our Waterbed Inserts page for more detailed information on various standard mattresses that are specially made to fit inside of a wood waterbed frame.
