Linenspa 6" Gel Memory Foam Mattress review

Linenspa's 6-inch Gel Memory Foam Mattress is the simplest foam option here, and the maker pitches it for exactly this job: it says the six-inch profile is designed to shine on bunk beds, trundle beds, RVs and guest rooms. The build is two inches of plush memory foam over four inches of gel-infused foam with a convoluted center meant to cushion pressure points and move air. Linenspa rates the feel medium-firm and suitable for side, back and stomach sleepers. The foam is CertiPUR-US certified, the cover is quilted cotton, and the twin measures 39 by 75 inches. It costs $119.99 for a twin on linenspa.com and carries a 10-year limited warranty. The weak point for a child's bed is cleaning: Linenspa says not to remove the cover and to spot clean only, so pair it with a waterproof protector. There is also no sleep trial on the product page, unlike Helix, Nectar and Novilla.
