Novaform is a mattress company that specializes in memory foam products. The company sells a diverse range of affordable mattresses, mattress toppers, and pillows. The current mattress lineup includes the Serafina Pearl Cool Mattress, the ComfortGrande Plus Mattress, the Overnight Recovery Gel Memory Foam Mattress, the Advanced Back Support Specialized Mattress, the SoFresh Responsive Foam Mattress, and a basic Gel Memory Foam Mattress.

The ComfortGrande Plus is one of the company’s most competitively priced mattresses. Standing at 14 inches tall, the mattress has room for a full support core and a thicker comfort system than most other mattresses in this price range.

The Novaform ComfortGrande Plus features a layer of gel-infused memory foam over a second layer of air channel foam, similar to convoluted polyfoam. The support core consists of 8 inches of high-density polyfoam. With a medium firm feel, the mattress is designed to appeal to the vast majority of sleeper types.

This memory foam mattress is an appealing choice for shoppers on a budget. We’ll take a closer look at the construction of the Novaform ComfortGrande Plus, and discuss how the mattress performs for different types of sleepers.

Mattress Performance

Motion Isolation

As an all-foam mattress with 3 inches of contouring memory foam, the ComfortGrande Plus excels at motion isolation.

The 6-inch comfort system absorbs excessive movement and prevents it from transferring across the surface of the mattress, reducing disturbances for sleepers who share the bed. Most people should be able to switch sleeping positions and get in and out of the bed without awakening their partner.

Pressure Relief

The ComfortGrande Plus has a medium firm feel that alleviates pressure points for most sleepers.

Memory foam is a naturally contouring material that conforms closely to the shoulders and hips to relieve pressure in these sensitive areas. The convoluted polyfoam in the second layer supports the lumbar area to prevent pressure buildup in the lower back.

Temperature Control

Temperature regulation is not a strength of the ComfortGrande Plus.

Memory foam is known for trapping heat. To get around this problem, the ComfortGrande Plus is constructed with cooling gel-infused memory foam and air channel foam designed to promote airflow.

However, while the ComfortGrande Plus may stay cool enough for some people, those who tend to sleep hot may want to consider another type of mattress. Hybrid, innerspring, and all-foam mattresses with more advanced cooling technology are more suitable for those who prioritize temperature regulation.

Edge Support

All-foam mattresses tend to offer below-average edge support, and in line with these expectations, the ComfortGrande Plus lacks a resilient perimeter. Despite the sturdy base, the mattress has a thick comfort system that compresses considerably under pressure.

Individuals who sleep near the edge of the bed, or who like to sit near the perimeter of the mattress, may need the stronger edge support of a hybrid or innerspring mattress.

Ease of Movement

Despite its medium firm feel, the ComfortGrande Plus Mattress may contour too closely for individuals who often move around during the night. The memory foam is slow to respond and may give some sleepers the feel of being trapped in the bed.

Individuals who frequently switch sleeping positions may prefer an innerspring, hybrid, or latex mattress. The materials in these mattresses are more responsive than foam alone.


Couples may find it difficult to be intimate on the ComfortGrande Plus Mattress. The mattress’ contouring memory foam and air channel foam don’t offer much bounce. As a result, couples may have difficulty changing positions. Some couples may also find the mattress can become uncomfortably hot.

For couples who prefer a bit of traction during sex, the ComfortGrande Plus may be more appropriate. Another advantage is that the mattress is virtually noiseless due to its all-foam construction.


While off-gassing is common with most foam mattresses, sleepers may find the ComfortGrande Plus takes a little longer to air out due to its thick profile.

Off-gassing refers to the levels of volatile organic compounds (VOCs) that a mattress releases when it is first unboxed. The foams in the Novaform ComfortGrande Plus carry the CertiPUR-US label, indicating they are low in VOCs. However, the mattress may still release some tiny particles that can give off an unpleasant odor during the first few days.

That said, this odor should dissipate over time. To accelerate the process, allow your mattress to breathe in a well-ventilated room for about 3 to 7 days before using it.

Side Sleepers

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.

Back Sleepers

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.

Stomach Sleepers

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.

Novaform Mattress Review Breakdown

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.
