Frequently Asked Questions
Do I need a special bed frame for a softside waterbed?
You do not need a specialized frame, but you must have a solid surface to support the mattress. A wooden platform or a sturdy box-style foundation works perfectly well. Just avoid using slatted frames with wide gaps, as the weight of the water will push the mattress through the slats. You want a flat, unyielding base that supports the entire footprint of the bed.
How much does a filled waterbed weigh?
A full-size softside waterbed can weigh anywhere from 800 to 1,500 pounds depending on the depth of the bladder. This sounds like a lot, but the weight is spread over a large surface area. Most residential floors are built to handle this load, but it is wise to place the bed near a load-bearing wall. If you live in an older home, you might want to confirm your floor joist capacity first.
Will I feel my partner moving during the night?
This depends entirely on the baffle system inside the bladder. If you choose a full-motion mattress, you will certainly feel every movement and ripple. If you prefer a calm sleep environment, opt for a multi-layer fiber mattress. These designs significantly dampen motion, making it much easier to sleep undisturbed even if your partner tosses and turns.
Is it hard to set up a softside waterbed?
Setting one up is straightforward if you have a garden hose and a helper. You simply place the liner, insert the bladder, and fill it to the recommended level. The most time-consuming part is waiting for the integrated heater to warm the water to your preferred temperature. This process can take up to 48 hours, so plan accordingly.
How often do I need to add water to the mattress?
You should rarely need to add water once the mattress is properly filled. A small amount of evaporation is normal over several years, but it usually does not affect the feel of the bed. If you notice the mattress feels too soft or you can feel the frame, you may need to add a few gallons to reach the ideal fill line. Always use a conditioner whenever you introduce new water to keep the environment sterile.
