Luxury Support 100 Chamber Mid Fill System Free Flow Luxury Support Innomax Waterbed Fluid Chambers A waterbed fluid chamber is a necessity for your softside waterbed. With a fluid chamber you have the ability to customize your softside waterbed to suit your exact tastes. You can get a free flow water chamber which will allow the water to circulate openly throughout the chamber. This will create more wave action and give you a softside bed with more motion. A waveless fluid chamber has fiber elements inside the water chamber that inhibit the flow of water. This will dampen the wave-effect in the mattress and create a more stable surface with less partner disturbance. This will reduce any motion transfer between partners, while still giving you the same great Sleep-on-Water feel. Available Mattress Sizes: Twin, Full, Queen, King, Cal King. Important Note: This is only the waterbed fluid chamber. For a complete bed system, you will need to include a Waterbed Heater. In addition we highly recommend: a waterbed safety liner, to catch any leaks; water conditioners, to keep the water in your waterbed from becoming unpleasant; and a fill & drain kit, to make filling your waterbed as easy as hooking up to the closest faucet. We offer get package deals on everything you need to get up and running with a new hardside or softside waterbed.
