Signature Sleep Braga 6-Inch Bonnell Coil Futon Mattress review

The Signature Sleep Braga is the cheapest way onto this list and the cheapest coil futon mattress we found with a clear spec sheet. It sits on a 12-gauge, 264-count steel Bonnell coil base topped with a thermobonded high-density polyester fiber layer, a combination the maker says is less prone to sag. The fill is 50% recycled polyester, the mattress is GreenGuard Gold certified, and it is assembled in Canada. It is a no-flip design that folds from sofa to bed in one movement and fits standard full futon frames. At $145 on Walmart.com when we checked, it undercuts every 8-inch pick by at least $37. The limits come from the format. Six inches of coils and fiber gives less cushioning than 8 inches of foam, Bonnell coils are wired together so they pass more motion than pocketed coils, and this listing is sold by a third-party seller rather than the brand. Signature Sleep rates it medium support.
