Symphony Sleep Adjustable Bases Compared: ES200 vs ES500 vs ES600 vs ES700
Symphony Sleep’s main adjustable-base ladder is easy to understand once you know what each step adds. ES200 handles the fundamentals, ES500 adds massage, presets, charging and under-bed lighting, ES600 adds active lumbar support, and ES700 adds the SonicSleep speaker/massage system.
Feature-by-feature comparison

ES200 vs ES500: the biggest jump in everyday convenience
The ES200 gives you the core adjustable-bed experience: independent head/foot articulation, wireless control, multiple height options and a memory position. ES500 is where the base starts to feel genuinely premium—massage, Zero Gravity, Anti-Snore, USB-A/USB-C charging, under-bed lighting, more memory positions and SleepSense compatibility all arrive together.
ES500 vs ES600: lumbar is the reason to upgrade
Most of the ES500 and ES600 feature set overlaps. The important difference is active lumbar support. If you specifically want adjustable support under the lower back, ES600 earns its place. If you do not care about lumbar adjustment, ES500 already gives you most of the premium convenience features.
ES600 vs ES700: the upgrade is SonicSleep
ES700 keeps the ES600’s active lumbar, presets, charging and premium frame features, then adds Symphony Sleep’s SonicSleep technology and under-bed speaker system. That makes ES700 the audio/sonic-massage flagship rather than a fundamentally different articulation platform.
The accessory ecosystem matters
Elevation Kit
The Elevation Kit is more than extra head lift. It tilts the entire base up to 12.5 degrees with its own lift motor and is compatible with ES200, ES500, ES600 and ES700. That creates a different body angle from simply raising the head section.
Hi-Low Lift Kit
The Hi-Low system raises or lowers the entire bed frame and adds Trendelenburg / reverse-Trendelenburg positioning. Symphony lists a height range from roughly 10 inches to 31.5 inches depending on configuration, making it a mobility-oriented accessory rather than a normal comfort upgrade.
SleepSense
SleepSense works with ES500, ES600 and ES700. Symphony says it can track heart rate and breathing, provide sleep scoring, and use audio monitoring to detect snoring and automatically move the base through preset anti-snore positions.
Which Symphony Sleep base should you start with?
- Just want articulation: ES200.
- Want the best feature/value jump: ES500.
- Want adjustable lumbar: ES600.
- Want the flagship sonic/speaker system: ES700.
- Need whole-bed incline: add the Elevation Kit.
- Need height adjustment for mobility/access: look at the Hi-Low Lift Kit.
Adjustable-base compatibility depends on the mattress and bed frame. Confirm current sizing, accessories and floor-model availability with Yawnder before ordering.
