What You're Getting

A split king Contemporary IV is two Twin XL bases that sit side by side under a split king mattress set, each moving independently, with a sync cable so you can also run them together. These are the showroom display units, so they carry the normal light handling marks of a floor model and are priced well under what they sold for new.

  • Adjustable Edge-to-Edge Lumbar Support
  • Motorized Head Tilt
  • Full Head and Foot Positioning — head incline to 65°, foot incline to 32°
  • Four Preset Programmable Positions: One-Touch Flat, Anti-Snore, Zero Gravity, and Leisure
  • 4 Easy Access USB Ports — USB-A and USB-C on each side
  • Programmable Wireless Ergonomic Remote and Voice-Powered Mobile App
  • Therapeutic Dual-Motor Massage
  • LED Motion Activated Under-Bed Light
  • Six Stackable Legs for Top Deck Heights from 4.6” to 18”
  • 850 lb Lift Capacity Per Base

Rizer Kit Assembly — included with the With Rizer Head Lift Kit configuration

The Rizer kit sits between the mattress and the deck and lifts the entire head section a further 5”, so the head of the bed rises as a unit instead of folding at the shoulders. It installs on the Contemporary IV without tools beyond the included hardware.
