Waterbeds and Electromagnetic Frequency (EMF)
What are electromagnetic fields?
Electrical currents are what causes electromagnetic fields. Common household current is alternating current (AC), which reverses its direction (its charge) then switches back. A complete cycle per second is one hertz (Hz). For example, if your waterbed heater operates at 60 Hz, then its current changes direction 60 times per second. This cycle creates electric and magnetic fields at the same frequency. The fields created by power lines that distribute power throughout the country are power frequency fields. These currents are nearly everywhere we live. It exists in cars, trains, elevators, massage chairs, tv's and video terminals, just to name a few. Emf is ubiquitous throughout our society.
Most waterbed heaters manufactured today are low emf, or emf reduced, thus minimizing exposure. For those who wish to exercise extra caution, a timer can be used to run the heater when waterbeds are not in use. This we will recommend during pregnancies just to remain on the safe side. A waterbed mattress will usually not require heat in the summer months or warm climates for many of us, though some will disagree. Again, this issue is only theory. Generally, scientists on both sides say they are dealing at most with rare diseases and an increased risk that is almost infinitesimal, especially compared with life's other everyday risks.
Conclusion;
No scientific data support definitive answers to questions about the existence or nonexistence of health risks related to wood frame waterbed heaters or softside waterbed heaters and electromagnetic fields. More research to produce more reliable information is needed before any conclusions can be drawn.

Waterbed Heaters and the Softside Waterbed
Deepfill waterbeds have eight inches of water, and are most similar to their hardside counterparts, requiring that a heater be used because the user is in close contact to the watermattress, which has about 200 gallons of water in a king size. A standard waterbed heater (300 watt) can be used on this type of waterbed, but only if it is placed on a wooden surface. If the deck surface is made of foam or fabric, a low-watt heater (120 watt) should be used instead to reduce the risk of overheating the heater, and scorching the foam or fabric surface, which can lead to heater failure or, in extreme cases, fire damage.
These lower wattage heaters operate at a lower temperature using a wire alloy heating element, which is a bit more expensive, instead of stainless steel or foil.
Midfill waterbeds have about six inches of water, and augment that with at least two inches of foam over and/or under the watermattress. A low-watt heater ONLY can be used for this type. Full watt waterbed heaters should never be used on a midfill waterbed, as they produce more heat than can be carried off and dispersed by the watermattress, creating an overheating hazard.
Shallowfill waterbeds do not need a heater, as the ambient air temperature, combined with body heat is adequate warmth. Shallowfill can be either a tube system, or a watermattress. While some may think it's safe to use a low-watt heater, aka a tube heater, we do not recommend doing so.
There is also the issue of electromagnetic frequency (E.M.F.) with regard to waterbed heaters to be discussed. This will be the subject of a later post.

Waterbed Sheets and Bedding Primer Part 2
If you have chosen a hardside, or wood frame waterbed, you will need to buy waterbed sheets. These come in 3 sizes; king, queen and super single. These are all california, or western sizes. They are 6, 5, or 4 Feet wide, respectively, all by 7 foot long. These dimensions were adopted industry wide to make the most efficient use of lumber in their construction. These sheets are often packaged as a set with a top sheet, bottom sheet, and 2 pillowcases. Super single waterbed sheets usually have only one pillowcase. When applied to a properly filled watermattress correctly, these sheets stay put very well. We will explore this further in the next blog.

Waterbeds and Sex Part 2- Sex and the Softside Waterbed
The deepfill is the softside type that is most akin to a hardside waterbed, as they are about the same depth and can be offered with the same watermattress types, and both require a waterbed heater. Depending which type watermattress is ordered will determine the amount of motion. Some models offer pillowtops, others come with a plushtop. The plushtop is thin, and leaves very little between yourself and the vinyl watermattress, while the pillowtop provides a soft, billowy buffer. Other than that, with regard to sex, the same rules apply as with wood frame waterbeds with one exception; the soft sides are made of foam instead of wood and can be much more forgiving in the event of any accidental impact (giving new meaning to safe sex!).
The midfill and shallowfill softside waterbeds are a hybrid of a waterbed and an innerspring bed (what we like to call a "dead bed"). Because a waterbed needs 8 inches of fluid support, these beds augment this with the use of foam. A midfill will use 6 inches of water, buffered with at least two inches of foam, and a shallowfill will have 4 inches of water, in either tubes or a watermattress, with a minimum of 4 inches of foam above and/or below the water. Heaters are optional on midfill waterbeds, and are NOT recommended on shallowfill waterbeds. All three types can be purchased with a plushtop or pillowtop, and some high-end models offer visco memory foam toppers. These beds are more comparable to regular mattresses because they move less, and allow for better "traction". Instead of using springs for base support, which will compress in the same place nightly from your bodyweight, and eventually sag, they use water, which will resilliently feel the same in 20 years as it does today, topped by a soft and supple foam or pillow top. It really feels great! They all will have some rocking motion, but the shallower the fill, the less action. Tube beds have almost no side-to-side motion, but will still have some head-to-foot motion, so you can still "go with the flow" on all types. (Of course, playing a Barry White cd may enhance your experience.)
I am now confident that, given the information here, you can make an educated and informed choice of which type of waterbed will best suit your needs for practicality, comfort, and fun. Please post any feedback or questions you may have on this or any other relevant subject.

Waterbeds and Sex Part 1- Hardside Waterbeds
When considering which type of waterbed might best suit your sexual preferences we offer the following primer; If you choose a hardside waterbed with a full motion (aka freeflow) water mattress, you can expect wild, exciting active sex. Alternately, a wood frame waterbed with a reduced motion, or waveless waterbed mattress would allow for a slower, more sensual sex. After having chosen your new indoor playground, (which happens to also be the most comfortable sleeping surface on earth), you may need to make some minor adjustments.
First, feel how the warm water relaxes you and your partner during foreplay. A heated waterbed mattress can stimulate blood circulation, priming your bodies for a sexual encounter.
Next, you may need to modify your technique. Methods that worked well before may no longer be the best approach on a waterbed. As any surfer knows, when it comes to waves, timing is everything. Familiarize yourself with the wave energy and notice the reaction of the bed in response to your movement.
You may need to experiment with a few various positions to see which ones work best for you and your partner. While some find it difficult to to get leverage on a waterbed mattress no matter which partner is on top, others find it to be unecessary and learn to just "go with the flow". Remember, for each movement you make you get two free. Now, all you need is love, tiger!

Waterbed Myths Part 3; The Seasickness Myth
Wikipedia defines seasickness as; "A form of motion sickness characterized by a feeling of nausea and, in extreme cases, vertigo experienced after spending time on a craft on water".
This is usually caused by visual confusion and inner ear imbalance due to loss of horizon and constant pitch and roll of the sea for a long period of time.
That said, let me go on the record as saying nobody has ever gotten seasick on a waterbed, period. Many people think it's just a funny thing to comment when they lay down on a full motion watermattress for the first time. As a salesman, many times I would chuckle to be polite, ever pretending to have heard it for the first time, but quickly changing the subject to waveless waterbeds as a "solution" for that "problem".
The truth is, we sell more full motion mattress than we do ultra waveless waterbed mattresses, which clearly indicates that many people love the gentle rolling motion of flotation sleep. A free flow mattress will rock for about 10-15 seconds after laying down, then it will remain motionless until it is pushed again. Different degrees of wavelessness are achieved by manufacturing watermattresses with more or less wave inhibitor inside. These are known as fiberfill mattresses. The greater the density and volume of fiber inside the mattress determines how much motion is reduced. An ultra waveless usually has 8-10 layers of nylon fiber throughout the entire inside (zero second stop), while an 80% waveless watermattress will have 3-5 layers occupying about two thirds of the interior (3-5 second stop). That is how wave reduction is achieved.
So let's hope this puts yet another waterbed myth to bed. Seasickness is caused by the sea, not by a waterbed!

Waterbed Myths Part 2- The Weight Myth
Thursday, May 22, 2008
Waterbed Myths Part 1
Let's start with this old favorite; "Waterbeds can burst". While it is possible for a filled waterbed mattress to explode if it were to be dropped from a ten story tower, (think David Letterman), it is not at all likely to rupture under normal circumstances. You see, the water in a properly filled waterbed mattress is not under pressure. A deep fill type mattress has about eight inches of water depth inside. So the stress near the bottom is about the same as a filled glass of your favorite beverage in a container the same height.
That said, I can attest to witnessing some extreme abuses of waterbed mattresses under abnormal circumstances, and can report that they have NOT burst, ever. Check out this video from one of our competitors in California doing a publicity stunt: http://technorati.com/videos/youtube.com%2Fwatch%3Fv%3Dmx1nbWjZ4oA .
While the video should speak for itself, I'll tell you about a few other bladder abuses that I have observed; I once filled a ten-plus year old, king sized full motion waterbed mattress on a beach at my vacation home for the kids to play on. Well, the kids loved it, and it not only was jumped on just about every day all summer, but a friend of mine actually backed her jeep over it (on purpose), and it never even sprung a pinhole. To this day, there is one in my back yard playground. As a salesman, I often jumped on the showroom models just about every day to demonstrate the strength of a waterbed, and I weigh over 250 lbs.
Back in the early eighties at a grand opening party for one of our retail showrooms, we had 14 adults piled onto a floor model for a photo op. I wish I could find that picture. That waterbed store has since moved to the internet.
As I said, the water is not under pressure. If you were to stab the surface of a properly filled waterbed, you would only see a few drops of water.
So, I think I have made my point. A correctly filled waterbed, whether it be a hardside, (wood frame waterbed) or softside, full motion or waveless water mattress, will not burst, even under extreme circumstances.
Now, on to the next myth.

How to Drain a Waterbed
Your first step as you begin to drain your waterbed is to make sure you have unplugged your waterbed heater. This is critical because as the heater loses a sufficient depth of water, it will overheat and eventually burn itself up, along with your liner and watermattress. This can be dangerous and expensive.
Next you will need to remove all the air bubbles that have accumulated inside the watermattress, also known as "burping" your waterbed. This is easily done by gently sliding a broom stick (or any similarly shaped device) with gentle, downward pressure, across the top surface of the vinyl, toward the uncapped valve, allowing any trapped gasses to vent out of the watermattress. This is also a critical step to evacuating as much water as possible. Remember, that the last ten gallons can be the most difficult to remove because as the water drains out, a vacuum is created inside, and as the bed empties out, any air present will negate the vacuum, making the mattress very heavy and bulky. So be sure to remove all the air bubbles before proceeding. Now you must choose which draining method you will use.
The first method of draining is to use a venturi pump. This is the T-shaped plastic fitting found in a waterbed fill and drain kit. Most reputable waterbed dealers will provide this with the sale of a waterbed, and they should have come with instructions. While these do work well on free flow and semi-waveless water mattresses, they are not recommended to drain an ultra-waveless (90-100% wavelessness) mattress. This is because they do not provide a strong enough vacuum that is needed in order to drain them sufficently to be picked up. These pumps rely on water pressure and gravity. They are only effective with the water flowing downhill, and with strong water pressure. The tap water must be kept running until the mattress is empty. This is the most inefficent and time consuming method. It also wastes a lot of water.If you live in a basement, it may be your only choice, unless you can get your hands on an electric pump.
An electric pump is usually the fastest method. How fast is determined by how powerful your pump is, and whether the water is flowing up or downhill. Most will take 30-90 minuites. This is the most effective way to drain an ultra waveless watermattress. If you live in an apartment building, place the hose as deep as possible into a toilet bowl, and close the lid before starting. Many pumps will need to be primed (pre-filled with water) in order to get started. This method, of course, requires electricity.
The siphon method will require only a hose. A male hose adapter, which also comes with a fill and drain kit, is helpful, but not necessary. Following the above instructions, next, place the male end of the hose into the valve of the waterbed. The other end of the hose needs to be placed as low as possible, in relation to the mattress. The more vertical drop, the faster the bed will drain. Next step is to suck on the lower end of the hose to start the water flowing. Once it begins to flow downhill, it will continue to do so until there is no more water left. For the squeamish, a wet-vac can be used to start the siphon.
Whichever draining method you choose, it is also important that you replace the plug and cap quickly after removing the hose from the watermattress, preserving the vacuum. Do not allow it to back fill with air. This will ensure that the fiberfill inside a waveless mattress will not shift, and bunch up into a big lump. This will be the subject of my next blog; Fibershift.

About the Waterbed Guy
Filling Your Watermattress
What is the ideal waterbed depth? In my quarter century + of experience as a professional waterbed installer and service provider, this has been the most insideous problem that has faced the waterbed industry. First of all, water cannot be compressed. It is physically impossible. That said, overfilling a watermattress can only be problematic. It can't get firmer, but it will get rounder (hemispherical). You want it to be box shaped. It is cut to be filled to a certain depth (usually 6-8"). Exceeding the recommended depth will:
-Stretch the vinyl and weaken the seams.
-Increase electrical consumption (more water to heat).
-Stress and warp the sides.
-loosen screws and break brackets.
-Cause undue stress to supporting structures.
-Make it more difficult to tuck in sheets and bedding . (excess weight to lift)
-Make your bed LESS comfortable.
I have seen this all happen firsthand.
An air mattress will get firmer as you add more air, because air beds are filled with a gas, not a liquid. Gasses will compress. liquids cannot.
Underfilling is the lesser of two evils. It only causes bottoming out on the deck when sitting or kneeling, but that can lead to overheating the heater and damaging the vinyl (and the heater).
I have seen properly filled waterbeds last 20+ years. The best advice i give to my customers on filling a waterbed is to lay a broomstick, or similar device across a wide corner of your hardside or softside waterbed at it's lowest point. When the water level begins to lift the broomstick off of the wood or foam frame, shut off the water. Adding more water is of no benefit to you.
Now, disconnect your hose from the sink, and as you coil it, hold it higher than the bed to let it drain into the bed. After that, couple both ends of the hose together to prevent spillage.
Next is the burping process. this is easy if you didn't overfill your watermattress. Gently use the broomstick to influence any trapped air bubbles to move toward the open valve. You can usually see them in sufficient light. Lay the stick flat on top of the mattress like you are floating cement, gently pushing the air towards the valve. Repeat this a few times. The air will easily vent out until there is no more splashing noise inside. This should be done again as necessary. The best time to do it is when you change the sheets. But, if you like a noisy bed, leave the bubbles in. It is not a critical step.
Before replacing the cap, you now should now add the waterbed conditioner. Which will be the subject of the next blog.
