The TEMPUR-Ergo 3.0 adjustable base combines head-and-foot positioning with adjustable lumbar support, massage, under-bed lighting and USB charging. It adds physical comfort and bedside convenience features above EASE without requiring the Sleeptracker-AI features of the Smart models.
TEMPUR-Ergo 3.0 features
Adjustable lumbar support
Raise the lumbar section to change the support you feel beneath your lower back.
Head and foot positioning
Use the wireless remote for separate adjustments, Zero Gravity, QuietMode and a return to flat.
Massage and convenience
One-zone massage, lighting and charging add useful options to your time in bed.
Positioning and massage controls
Choose a preset as a starting point or adjust the head, foot and lumbar sections to your preference. QuietMode raises the upper section to an anti-snore position; it is a manual positioning feature, not the automatic snore-detection system found on the Smart bases.
One-zone massage provides a vibration feature for relaxation. Keep the remote for the supplied base generation with its matching operating instructions.
Lumbar support, lighting and charging
The lumbar section can raise up to six inches to change lower-back support independently of the main head-and-foot adjustments. Try different positions with the mattress you intend to use rather than selecting a base on features alone.
Under-bed lighting provides low-level illumination around the base. Built-in USB charging keeps compatible devices close while you read or relax.
Sizes and dimensions
Choose from the sizes shown in the product selector. The dimensions below describe the base, which is intentionally slightly smaller than the corresponding mattress.
| Configuration | Approximate base dimensions |
|---|---|
| Twin XL / Twin Long | 37.5 × 79.5 inches |
| Full | 53.5 × 73.5 inches |
| Queen | 59.5 × 79.5 inches |
| King | 75.5 × 79.5 inches |
| Cal King | 71.5 × 83.5 inches |
| Split King | Two pieces; each approximately 37.5 × 79.5 inches |
| Split California King reference | Two pieces; each approximately 35.5 × 83.5 inches; not a selectable option on this listing |
The base platform is approximately 3.67 inches high without legs; dimensions may vary. Stackable legs offer 3, 6, 9 or 12 inches of leg height. A suitable zero-clearance platform installation is also possible under the manufacturer's instructions.
Mattress and Split King compatibility
Use a mattress approved for adjustable-base articulation. Split King arrangements use two Twin XL mattress and base sections for separate positioning. A solid King mattress and a one-piece Split Head mattress have different movement requirements; they should not be treated as interchangeable with a fully split mattress system.
For the mattress configuration, use our Split King mattress guide. For frame-fit and feature questions, see our adjustable-base guide.
