Description

Head and feet adjust independently, a wireless remote runs the show, and two USB ports charge the nightstand clutter — the Cosmic Power Base covers the adjustable essentials without ceremony or a premium invoice.

Compatible with the foam, hybrid, and wrapped-coil mattresses that dominate modern bedrooms, and now sized Twin XL through California King on one listing, it is the base for readers, late-night TV watchers, and anyone whose circulation appreciates raised feet.

Galloway, Linwood, and Ventnor shoppers can run it through its positions at The Mattress Store inside our Northfield showroom — the remote explains itself.
