The Novaform ComfortGrande Plus Mattress is an all-foam model with three distinct layers. These include a comfort section made with gel-infused memory foam and air channel foam, and a high-density polyfoam support core. All of the foams used in the mattress are made in the U.S.
To help fight the heat retention that is typical of memory foam mattresses, the ComfortGrande Plus contains 3 inches of proprietary EVENcor GelPlus memory foam in its top comfort layer. The gel infusions aim to maintain a consistent temperature by drawing away heat from the surface of the mattress. Memory foam also hugs the sleeper and cushions potential pressure points in the shoulders, back, and hips.
Underneath this layer of memory foam is 3 inches of air channel foam. This foam has a ridge-like design similar to an egg crate, designed to enhance breathability by allowing air to flow through. The grooves also help reduce pressure points by lifting the lower back and preventing the spine from sinking in too deeply. The ComfortGrande Plus has a medium firm feel, or a 6 on the 10-point firmness scale.
In the support core, 8 inches of high-density polyfoam provide a durable base that helps maintain proper spinal alignment.
Encased in a quilted cover, the mattress has a 14-inch profile. Due to the above-average height of this mattress, deep pocket sheets may be necessary.

Compared to many other memory foam models, the ComfortGrande Plus Mattress comes in at a below-average price-point. Moreover, Costco frequently offers discounts on Novaform products, which can significantly lower the sticker price of the mattress.
This mattress is available in five standard sizes: twin, full, queen, king, and California king. Novaform does not offer a twin XL option.
Despite being slightly heavier than some foam mattresses due to its extra height, the mattress has sturdy handles on each side that allow customers to move it more easily.
Most side sleepers should find the ComfortGrande Plus Mattress suitable for their needs. Side sleepers need ample cushioning around their shoulders and hips to prevent pressure buildup, and pressure relief is where the ComfortGrande Plus Mattress stands out.
The gel-infused memory foam and air channel foam cushion sharp pressure points, while 8 inches of high-density polyfoam in the mattress’ support core gently support the hips and help keep the spine aligned.
For side sleepers under 230 pounds, the ComfortGrande Plus Mattress provides the right balance between cushioning and support. The mattress is particularly appropriate for individuals between 130 and 230 pounds, as side sleepers under 130 pounds may prefer a slightly softer mattress for deeper contouring.
Sitting at a 6 on the 10-point firmness scale, the ComfortGrande Plus may feel too soft for side sleepers over 230 pounds. Individuals in this weight range typically need a firmer mattress for optimal support. This mattress’ plush comfort layers allow the hips to sink in too deeply, which can shift the spine out of alignment.
The Novaform ComfortGrande Plus is an excellent choice for back sleepers under 130 pounds. Back sleepers do best with a mattress that delivers equal parts pressure relief and support to keep the spine on an even plane. The mattress’ combination of contouring comfort layers and supportive high-density polyfoam help align the spine and contour to the lumbar zone for maximum pressure relief.
Back sleepers between 130 and 230 pounds should also find the ComfortGrande Plus adequate. For these individuals, the mattress cushions the upper body without causing excessive sagging. However, some back sleepers between 130 and 230 pounds may prefer a firmer mattress that delivers more support for the lumbar spine.
Despite its 8-inch support core, the ComfortGrande Plus may not feel supportive enough for back sleepers over 230 pounds. These sleepers exert more pressure on the mattress and may find their hips sink in too deeply. Not only can this push the spine out of alignment, it may also cause pressure buildup in the lower back.
The ComfortGrande Plus Mattress is a suitable choice for stomach sleepers under 130 pounds.
Stomach sleepers typically need a firm mattress that supports the midsection to avoid straining the back. Individuals who weigh less than 130 pounds don’t sink as far into the mattress. These sleepers should find the mattress relieves pressure from the lower back while keeping the spine aligned.
Individuals who weigh more than 130 pounds may find the mattress is too soft, allowing the hips to sink and putting pressure on the lower back. This is particularly true for stomach sleepers above 230 pounds. Stomach sleepers weighing more than 130 pounds usually need a firmer mattress to maintain healthy spinal alignment.
