Overview

Sealy Ease 4.0 Adjustable Foundation, Twin XL

The Sealy Ease® 4.0 Adjustable Foundation is a power base built for the sleeper who wants ergonomic positioning without a complicated setup. Raise your head to read, elevate your feet after a long day, or tap into Zero-Gravity mode and let the base lift both ends until your back stops feeling the weight of the world. Whatever position you land on, Position Lock holds it there all night. No creeping back to flat while you sleep. The slim, low-profile frame slides cleanly into existing bed frames, platform bases, or headboard setups. Stop by any Mancini's Sleepworld location and our sleep specialists will walk you through every position side by side so you can feel the difference before you decide.

COMFORT AND FEEL: Fully adjustable positioning delivers personalized support from head to toe throughout the night.

SIZE: This Twin XL sized foundation is a smart fit for taller single sleepers, college setups, and split-king configurations with an independent partner.

BEST SLEEP MATCH: Ideal for back sleepers and combination sleepers who want to relieve lower back tension or reduce pressure by dialing in a custom elevation that a flat foundation simply cannot offer.

BEST FOR: Ideal for sleepers dealing with lower back tension, acid reflux discomfort, or anyone who reads, works, or watches TV in bed.

CONSTRUCTION SPECIFICATIONS: The steel frame sits on four-in-one tapered legs you can adjust to 3, 6, 9, or 12 inches without tools. The deck surface is firm and stable so your mattress stays flush at any angle. A battery backup keeps the base from trapping you elevated if the power goes out. The child lock feature secures the base from moving with a simple two-button sequence.

SETUP AND COMPATIBILITY: Delivered flat with white-glove in-home setup included. Works with platform frames, adjustable-compatible mattresses, and existing bed frames with or without legs. No box spring required.

NOT A FIT FOR: Sleepers expecting massage or anti-snore features, as the Ease® 4.0 focuses on clean, reliable positioning without add-on settings.
