Overview of the 400SX Super Waveless Waterbed Mattress
The 400SX is one of our most popular models because it prioritizes the support that many people are looking for when they browse waterbeds: lower back support. Super wave reduction and three layers of lumbar support keep you comfortable and supported all night long, so you wake up feeling rested and pain-free.
- Three lumbar layers
- Super wave reduction
- Seven comfort layers
- 2nd most waveless
Wave Reduction
Super wave reduction reduces motion transfer to help you fall asleep and stay asleep, even when your partner moves. The 400SX falls in our second tier of wave control with the perfect combination of stability and cloud-like softness.
Triple Lumbar
Three layers of lumbar support help eliminate sleep-related back pain by holding your spine in a more natural position throughout the night. Whether you sleep on your side or your back, the 400SX provides support where you need it.
