Features of 600SXE Super Waveless Waterbed Mattress
The 600SXE offers the highest level of wave control available, so you can fall asleep fast and stay asleep all night without disturbing your sleep partner. The Progressive Rate Spring layer provides additional support along the lumbar region to prevent back pain and along the edge to keep the mattress level with its frame.
- Progressive Rate Spring
- Six Layers of Support
- Tethered Wave Control
- Most Waveless
Minimal Transfer
For some sleepers, waves can make it difficult to fall asleep and might wake you up when your partner moves during the night. The 600 SXE minimizes motion transfer so you can fall asleep and stay asleep.
Individualized Support
The struggle to find the perfect balance of firm and soft is over. The Progressive Rate Spring system creates individualized support based on each sleeper’s weight, adjusting to each part of the body independently.
Lumbar Support
Additional support along the lumbar region gives your spine the support it needs to maintain its natural curvature whether you sleep on your back or side, so you don’t wake up in the morning with posture-based back pain.
Edge Support
If you ever rolled around on a waterbed in the 90s, you might remember rolling into the corner between the water bladder and the mattress’s frame. Back then, it was fun, but today, you can sleep through the night without falling in.

Best Waterbed Mattress EVER!!!!
I love my new 600SXE Super Waveless Waterbed Mattress. I've been sleeping on a waterbed for the last 25 years and this waterbed mattress is by far the best I've ever had. The whole buying experience was outstanding!!!


Received replacement mattress in days
Excellent--we're impressed!

This review is simple. The 600SXE is without question, the most comfortable mattress that I’ve had..,. Maybe ever. Thank you Sterling! Extremely happy with my purchase decision, and a comment like that from me happens almost never.

Love my new 600SXE waterbed mattress!
We love our new 600SXE waterbed mattress! We previously had the 400 version and I loved that one too, but for the replacement we needed, we decided to try something a little more firm. The first night I couldn't decide if it was too firm or not, but after that I can tell you that it is just perfect. I sleep so comfortably and love that it is a litte more firm and more waveless. Every waterbed should be like this!

Happy with our Sterling Sleep Systems 600SXE Super Waveless Edge Support Back Support Hardside Waterbed Mattress
