No sourced tester review yet.
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. (1 sourced review.)
Praised: Premium Plus adds pillow tilt, lumbar support, head/foot massage, three memory settings and motion-activated under-bed lighting on top of the four presets; App- and remote-controlled presets (zero-gravity, lounge, anti-snore, flat) work seamlessly with Purple Essential, Premium, and Luxe mattresses; Useful for people with back pain or snoring via the zero-gravity and anti-snore presets and lumbar support.
Flagged: Recommended mainly if you already own a Purple mattress, not as a standalone buy; Source is an editorial preview, not a hands-on lab test, so there is no measured performance data (motor speed, articulation angle, dB, stability).
