Super Waveless Softside Waterbed Mattress
The third layer of lumbar support in the ER400 makes it one of our most popular models. Most sleepers struggle with back pain on mattresses that are too soft and body aches on beds that are too firm. This super waveless model gives you extra support where you need it and responsive cradling where you don’t.
Three Lumbar Layers
As sleep system designers, we take back pain seriously. You don’t have to accept inadequate support. The ER400 will cradle the natural curvature of your spine with three lumbar layers to eliminate your pain.
Four Full-Size Layers
Four 1.5-ounce fiber layers envelop the water bladder to provide structure, stability, and dreamy comfort. You’ll feel weightless and serene atop our most popular model and wake up feeling energized.
Super Waveless
The seven layers and tethering system of the ER400 Softside Waterbed Mattress minimize motion so you can get comfortable faster, sleep through the night, and avoid disturbing your partner.
Deep Bladder 8”
Why choose a deep water bladder? You want to sleep like a weightless baby on plush, cloud-like comfort, and that requires more than six inches of water. If you’re looking for more firmness, try our mid-fill.
The Real Benefit
Unlike foam beds in a box, innerspring beds or air beds, waterbeds never get softer with time. The level of support you feel the very first night, is the same level of comfort you will get 5, 10, 15 years or beyond from now, making waterbeds right right choice for most sleepers. While most traditional beds may only last 8-10 years, our waterbeds are able to remain in use up to 30 years with proper care.
United StatesAmazing product
The product and customer service are top notch! If you are looking for a water bed product, this is the place to go!
United StatesBeyond Comparison
There is no comparison to a Sterling Softside. We have tried multiple brands (and types) of sleep systems. By far, Sterling Softside waterbed mattress outweighs any type of mattress system. This is our second order due to age of our first mattress system. Once you sleep on a Sterling waterbed, there is no return to a regular mattress. The back support is beyond imaginable. I have high body heat when sleeping. The Sterling Waterbed system zeroes this issue out which makes sleeping at night quite snug.
United StatesKing Waterbed
Excellent experience from setup to sleeping! Had a soft side waterbed 8 years ago & loved it. So after experiencing the memory foam, decided to go back to a waterbed. Anton was very helpful with answering my questions & recommending the right choice in our bed. Thank you!!
United Statesreview if super waveless softside waterbed mattress(s)
I like the mattress and customer service was very quick and courteous. I ordered two new mattress bladders and received them within two days. The reason that I had to order the bladders was that one sprung a leak and I have no idea how or where it was. I only know it sprang a leak because the liner did not hold the leaked water and the frame was wet. The sterling system is good - if it didn't spring a leak. Mattresses were about 4-5 years old.
United Statesvery satisfied
Having waterbed for well over 30 years, I am very satisfied with this ER400, it's firm and waveless.
