About The Smooth Top Softside Waterbed Mattress Deep Fill


Is there a sleep system that can do everything? We believe the answer is yes, it’s our Geneva FR8300-127 or Smooth Top Softside Waterbed Mattress. This particularly rare and hard-to-find sleeping surface is basic in design like the old waterbeds of the past which really helps to lower your final cost. This floatation mattress really brings back that memorable waterbed feel everyone loved so much from days gone by, but with all of the modern conveniences.


It is constructed with a unique Stretch Kit Smooth Top Softside Waterbed cover that zips on or off and includes an even bigger throwback, a deep fill 8″ water cavity. The end result is an extraordinary night of temperature-controlled support and luxurious floating comfort. The stretch knit fabric is our only cover that is machine washable, (see instructions) durable, and smooth.


The best part is that it does not interfere with the old-fashioned “waterbeddy” feel. When we say a no-frills cover, it means without a bunch of quilting like pillow tops that for some take away from that old-time waterbed feel. Additionally, without a euro or pillow top, there is no thick quilted surface that can flatten out over time.


This top with this stretch knit cover is for a waterbed purist that is fed up with their regular coil spring mattress. This dreamy sleeping surface is like nothing else you will ever find, plus its modular design is easy on the environment. This 100% completely customizable floatation bed offers sleeper’s the experience of complete muscle relaxation through unmatched pressure relief.


The sleep system is regulated with a temperature control system to warm or cool your sleep environment throughout the night. A person can regulate the temperature of their home or car, why shouldn’t they be able to control their mattress temperature as well? With the simple touch of an easy-to-use digital readout control, simply choose your favorite temperature setting or opt-in for optional individual temperature controls for each sleeper.


Upgradeable Interchangeable Sleeping Surface Layer


When it’s time to replace or upgrade your mattress cover, you can choose from 4 different cover options: Stretch knit, plush comfort, standard pillow top, or deluxe euro top.


  1. 8300-127 Stretch Knit Top Geneva Softside Waterbed Top
  2. 8300-167 Plush Top Geneva Softside Waterbed Top 
  3. 8400-247 Pillow Top Geneva Softside Waterbed Top
  4. 8500-167 Deluxe Euro Pillow Top Geneva Softside Waterbed Top

The “top panel” is the bed surface and is upgradable or downgradable to help improve the contouring comfort of your Sterling Softside Waterbed. The Stretch Knit  Smooth Top Softside Waterbed Mattress Cover is an ultra-thin and flexible top panel. It is treated with aloe vera to make the fabric very soft and is the very top layer next to your body.


The removable cover can be easily unzipped at the head end and reattached for easy moving, replacement, or to simply change the surface feel in just a couple of seconds. This top cover adds a traditional 1970’s waterbed feel that mimics the old traditional wood-framed waterbeds with a vinyl mattress.  It is safe to say that if you like the old hardside waterbed feel with a thin white mattress pad, you are going to love this modern take.


This comfort encasement creates just a little bit of space between the body and the mattress surface to add comfort, protection, and breathability without changing or affecting the feel of the mattress underneath. It also does not affect the support from the mattress below. If you decided this good old-fashioned feel is for you, now it’s time to decide on whether you prefer the mattress with a lot of wavy movement or not? Choose one of the water bed bladders (mattresses) from below.


Extend the life of your Smooth Top Softside Waterbed Mattress Deep Fill indefinitely with replaceable parts. Every part and piece of this bed can be replaced should it wear out or upgraded and changed if you so choose. Example: It includes a top panel that can be zipped on, replaced, and upgraded, in just seconds. It unzips like your jacket and separates the top panel from the bottom panel. Think of it as a bucket with a lid that zips on.


The side rails come as a set and the end rails come as a set. Should your sides lose their original shape, wear down, or be lost in a move one set of rails can be replaced. NOTE: Many companies only sell 1 piece side end and end rail tubs. If 1 side or end rail goes bad, the entire one-piece tub will have to be replaced at a greater cost.


Earth Friendly Design Water Mattress


Why replace a whole bed when you can simply replace the support and comfort portion. Save money and the strain on the environment by replacing old what needs to be replaced instead of a whole new bed. Top, sides, foundation, mattress, heater liner. Whatever needs replacing or you want to change. It is up to you.


Wave Reducing. We Offer 4 Different Bladders To Choose From:


The Smooth Top Softside Waterbed Mattress can conform naturally to your body’s curves, to help minimize painful pressure points for increased blood flow (circulation) that causes tossing and turning and disturbs sleep.


Choose from a wide variety of mattresses that can increase support, reduce wave movement, disturbance from one person to the other, and increase comfort. NOTE: Additionally, you can dampen wave movement with a thicker more luxurious zip-on topper panel. The second rating below is the approximate amount of time it takes the water movement to settle and stop. The best part is you can upgrade or replace just the mattress/ bladder for the best deep sleep and restorative healing without buying a whole new bed.

Product Features


Smooth Top Softside Waterbed Mattress Contains The Following:


  • Mattress Thickness: 8″.
  • Zippered Encasement: Removable Stretch Knit Top panel and Bottom bucket. Easy to zip on or easy to zip off.
  • Super Heavy-Duty Zipper: Made from molded plastic, while it takes more time, precisely sewing each corner and having a precise number of teeth allows for easy removal or replacement of the top mattress panel without the need to drain the water out of your bed. Other brands save money with cheap smaller toothed zippers that are quickly sewn on. Their top panel is NOT Removeable and the bed must be drained to change or replace.
  • 8” Deep Fill Design: Best simulates that old wood frame waterbed feels and support. Won’t bottom out when you are sleeping like 6” and 4” deep versions.
  • Comfort Perimeter: Includes 4 Heavy Duty Foam Side Rails and End Rails. The Sterling 8″ Softside Foam Rails have a slanted design to decrease outward wall pressure from the water while maintaining a comfortable seating edge.  The head and foot rails are connected to each other by fabric, as are the left and right rails. They include a 2-stage layered design. Top foam has 1.8 density and is softer for an easy transition in and out of the bed. The 2.0 super high-density transition foam supports you as you transition. You won’t feel like you are climbing over an old wood frame like waterbeds from the past.
  • Wrapped Side and End Rails: Heavy-duty fabric connects the side rails. Simply unroll them and put them into place. Do the same with the end rails. The weight of the water helps hold the rails in position and keeps them from losing their shape and bowing with use and age.
  • Sloped Inner Wall Design: This design will increase sleeping space, after all, additional sleeping space leads to greater comfort. The side and end rails that make up the waterbed cavity are sloped like a hillside. This increases overall sleeping space, giving both sleepers more room than thicker vertical wall designs. Additionally, by sloping the wall like the back side of a dam, it helps disperse the weight of the water pressure that pushes outward and makes most vertical walled soft sides start looking like an old whisky barrel in shape over time.
  • Energy Efficient Low Watt Softside Waterbed Heater: We only use a solid-state waterbed control unit. Our heating system focuses on the details. Our large heating pad is extremely safe and includes overheat protection and is very reliable. No other waterbed heater lasts longer. Easy to read digital control for day or night. Easy to operate and install. See full instructions for care and operation instructions. It is recommended these days to put a heater in the bed. Dual systems should have 2 heaters. One for each bladder and individual temperature control.
  1. Prevents condensation, mold, and mildew.
  2. Keeps vinyl warm and pliable so vinyl does not get stiff and cold crack after time.
  3. Maintains comfortable healthy sleeping temperatures.
  • Fitted Safety Liner: 8mil thick vinyl. Fits perfectly with deep fill softside waterbeds measuring 8 inches deep. This is designed to hold the contents of a leak in the improbable instance you should ever have a leak.
  • Waterbed Fill and Drain Kit: Includes all the necessary tools to not only fill your water mattress but also to drain it down, completely. The pieces that are included allow you to connect your new clean garden hose to the closest sink available. You can do this using included faucet adapter.
