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. For the trade-offs between the two, read our ES500 vs ES700 comparison.
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; ES200 may require additional components. That creates a different body angle from simply raising the head section.
Hi-Low Lift Kit
The separately purchased Hi-Low Lift Kit raises or lowers the entire bed frame and adds tilt positioning. Symphony lists a height range of roughly 10 to 31.5 inches and lifting limits of 350 lb per Twin XL side or 650 lb for Queen. These limits differ from some base ratings. Verify the size, combined load, compatible parts and installation requirements before ordering.
SleepSense
The optional SleepSense accessory 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 positions. It is a consumer comfort and tracking feature; consult a clinician for concerns about snoring or sleep-disordered breathing.

Frequently asked questions
Does ES500 have adjustable lumbar support?
No. Symphony lists active lumbar on the ES600 and ES700. The ES500 still adjusts the head and foot sections.
Is the Hi-Low Lift Kit included?
No. It is a separate accessory. Check the model, size, installation requirements and its own load rating before purchasing.
Can a split king move independently?
Two compatible Twin XL bases and mattresses generally allow each side to move independently; confirm the configuration, controls and any synchronization options with the seller.
Can I return an adjustable base to Yawnder?
Adjustable bases are final sale under Yawnder’s return policy. Confirm the written terms and compatibility before ordering.
Adjustable-base compatibility depends on the mattress and bed frame. Confirm current sizing, accessories and floor-model availability with Yawnder before ordering.
