Lucid Gel Memory Foam Topper review

Lucid's Gel Memory Foam Topper comes in 2, 3 and 4 inch profiles, and the 3-inch version is one of the cheapest ways to get a meaningful layer of memory foam from a brand's own store. Buyers choose a cooling gel, bamboo charcoal or lavender infusion, and Lucid says the foam is ventilated for airflow and meets CertiPUR-US standards. Sizes run from twin to California king and include split king, split queen and split California king halves for adjustable bases. When we checked, a 3-inch twin with cooling gel was $69.99 and a 3-inch queen with lavender was $99.99, though some infusion and size combinations were out of stock. Lucid includes a 30-night sleep trial, free shipping and a 3-year limited warranty. There is no cover, and the foam is spot clean only, so plan to put a mattress protector over it.
