Side Sleepers

The all-foam ViscoSoft Edge Mattress works well for side sleepers of all body types. Its memory foam comfort layers contour to the body’s natural curves, which is essential for side sleepers because they need the mattress to accommodate their hips and shoulders.

Additionally, the slightly springy polyfoam in the comfort system and dense polyfoam in the support core distribute weight evenly, ensuring side sleepers aren’t enveloped by the softer comfort layers.

Our testing shows that side sleepers weighing less than 230 pounds receive excellent support and comfort from the ViscoSoft Edge. Those over 230 pounds may experience slightly deeper sinkage but are still well supported.

Back Sleepers

Back sleepers generally don’t need significant pressure relief or cradling, and instead require a mattress that firmly supports their spine. While the Edge’s soft memory foam comfort layers conform closely around the body, the more responsive polyfoam layer beneath offers buoyant support. The 6 inches of high-density polyfoam in the support core also adds to the bed’s medium firmness and keeps the spine from falling out of alignment due to deep sinkage.

Our tests demonstrate that the ViscoSoft Edge Mattress provides excellent spinal support and appropriate cushioning to back sleepers weighing less than 130 pounds. Back sleepers between 130 and 230 pounds also enjoy a good sleep experience. Those weighing more may want to consider a firmer bed with less contouring for stronger posture support.

Stomach Sleepers

Stomach sleepers require the most significant support and need the least contouring. Without adequate firmness, some stomach sleepers experience sinkage in the abdominal and chest areas, leading to poor posture, discomfort, and sleep disruption.

The ViscoSoft Edge Mattress’ medium firmness level and plush cushioning don’t give most stomach sleepers the firm support they need to keep their spine aligned. The polyfoam in the bed’s comfort system and support core doesn’t sufficiently counteract its softer memory foam materials, making it a questionable choice for stomach sleepers weighing more than 130 pounds.

However, stomach sleepers under 130 pounds receive adequate support since they put less pressure on the mattress and experience less sinking.

ViscoSoft Edge Mattress Review Breakdown

The ViscoSoft Edge Mattress is topped with a cozy, visually appealing cover that’s knitted with phase change yarn. The phase change material is engineered to regulate temperature by absorbing and dissipating heat.

Beneath the cover, a 2-inch layer of silver-infused memory foam in the comfort system provides posture support and cushioning. An additional 2 inches of plush memory foam offers gentle contouring to relieve pressure points while minimizing motion transfer. A 2-inch layer of polyfoam completes the comfort system. Called faux latex, the polyfoam has a bouncy feel similar to natural latex that prevents deep sinkage and promotes spinal alignment.

In the support core, a 6-inch layer of high-density polyfoam reinforces the comfort system and the bed’s perimeter. The dense foam adds durability, reducing the chances of premature sagging. The base of the mattress is wrapped in a jacquard-knit cover with anti-slip beads for extra stability. 

The combination of foam materials in the ViscoSoft Edge Mattress creates a medium firmness level that adequately supports a range of sleepers. Its pressure-relieving design is especially well suited to side sleepers, as well as back sleepers who weigh less than 230 pounds. However, heavier back sleepers and stomach sleepers over 130 pounds may prefer a coil-based hybrid or innerspring model that provides greater support and a firmer feel.
