Milliard 6-Inch Memory Foam Tri Folding Mattress review

Milliard's 6-inch tri-fold is the most clearly documented folding mattress we found. The listing spells out the build: 1.5 inches of 3 lb memory foam on a 4.5-inch supportive foam base, CertiPUR-US certified, under a removable jacquard bamboo cover with an anti-slip bottom. Flat, the cot size measures 75 x 31 x 6 inches; folded, it becomes a 31 x 25 x 18 inch block that fits in a closet. Milliard describes it as ventilated for airflow and suited to guests, dorm rooms, camping and travel, and the listing says the same tri-fold comes in Twin, Full and Queen, so it scales from a single sleeper to a couple. At $129.99 for the cot size when we checked, it costs a little more than the Soges and VK Living twins, which are wider. The 31-inch width is the main limit: larger adults may prefer a twin. Walmart also lists the comfort level as firm and shows no written warranty. We compared documented features and published prices and did not test it.
