## What reviewers say

**Purple Premium Plus Smart Base** — Only one whitelisted source, Reviewed (USA Today), covers the exact Purple Premium Plus Smart Base, and its September 2023 piece is a non-hands-on buying preview rather than a lab test, so no measured performance data exists. It highlights the Premium Plus extras (pillow tilt, lumbar support, head/foot massage, memory settings, under-bed lighting) and the app/remote presets, but frames the base mainly as an add-on for people who already own a Purple mattress.
