Mattress Type: Double-sided innerspring with double edge guard side supports

Warranty: 20-year total (7 full, 13 prorated)

The Quiet Night Duo mattress takes the same 13-gauge steel innerspring construction as the original Quiet Night and makes it fully double-sided, with six double edge guard side supports reinforcing the perimeter on both top and bottom, a sturdier system than the single-sided edge support found on standard innerspring mattresses. Comfort layers of quilted cover, polyurethane foam, and convoluted foam mirror each other on both sides, so flipping the mattress gives you the same supportive feel rather than a compromise.

Like every Monarch Rest mattress, craftsmen hand-assemble the Quiet Night Duo in Sugarcreek, Ohio, carefully insulating each foam layer against the innerspring beneath it to prevent premature wear or body impressions, a detail many mass-produced mattresses skip entirely. Because both sides are built to the same standard, you can flip it each spring and fall and rotate it head-to-foot in between, which keeps both sides wearing evenly for years to come.

Monarch Rest backs the Quiet Night Duo mattress with its full 20-year limited warranty, and you can add the optional PE Cool Cover upgrade if you tend to sleep warm. It pairs by default with a 14-slat wood foundation for a strong, solid base, though boxsprings and bunkie boards are also available depending on your bed frame. For shoppers who want the classic Quiet Night feel but value the extended life a flippable mattress provides, this is the natural upgrade.
