Novaform ComfortGrande Plus   Review

It's a Medium-Firm mattress, so it's best suited for average-weight back and stomach sleepers. It might offer enough pressure relief for lighter back and stomach sleepers, while heavier people may want something firmer. Most side sleepers will want a plusher mattress, such as the similarly designed Novaform Serafina Pearl, for extra pressure relief in the shoulder area.

The upper comfort layer of memory foam is 3 inches (7.5 cm) thick, and since it's quite soft, it contributes to the mattress's moderate sinking. However, you won't sink very far since the polyfoam layer below is much firmer. This 2.8-inch (7 cm) transition layer helps prevent you from feeling the much firmer support layer directly. This 8.3-inch (21 cm) layer of polyfoam adds support for the heavier parts of your body.

The memory foam upper comfort layer is medium-soft. You'll sink into it a little, depending on your weight, but it's not soft or conforming enough for many side sleepers, especially because the polyfoam layer below is much firmer. This layer and an even firmer polyfoam support layer help prevent the heavier parts of your body from sinking in overly far and help give the mattress its decent overall support performance.

All of the foam used in the mattress is dense enough to be considered good-quality foam. The most durable layer is the transition layer, which is made of dense, high-quality polyfoam that will resist sagging for longer than lower-quality foams. The upper comfort layer and support layer foams both just meet the standard for good-quality foam. This will help prevent sagging for longer compared with low-quality foams, but mattresses with high-quality foams will be more durable.

This mattress offers great body conformity for people in the heavier weight category. If you're sleeping on your side, your arm and shoulder will sink in enough to relieve pressure. It also performs decently for average-weight people. However, as expected for a Medium-Firm mattress, it won't let lighter people sink in enough for comfortable side sleeping.

This mattress feels decently enveloping. The upper comfort layers aren't very contouring, so less of the mattress's sleeping surface is in contact with your body, resulting in a less hugging feel. However, your whole body will sink into it quite a bit, so its upper comfort layers feel plush, which helps with pressure relief. If you're looking for a foam mattress that offers more contouring, consider the Novaform DreamAway.

This mattress offers different levels of support depending on your weight. It performs best for lighter people, who will be well-supported, so if you sleep on your back or stomach, your hips will stay in line with the rest of your body. While it's less supportive for average-weight and heavier people, it still offers satisfactory support for people in both weight categories. This makes it more suitable for average-weight and heavier back/stomach sleepers than some Medium-Firm mattresses.

It has a good cooling performance. It doesn't feel overly warm when you first go to bed, and it dissipates heat well overnight. It's cooling enough to keep most people comfortable. However, if you're a hot sleeper, you might prefer a memory foam mattress with better cooling, such as the SweetNight CoolNest or the Silk & Snow Mattress.

It has fantastic motion isolation. You'll only feel movements near where they originate, and may not feel smaller movements at all. Motion dissipates quickly, so you never feel like the mattress wobbles when someone rolls over or a pet jumps into bed.

The Novaform ComfortGrande Plus is fairly responsive. It's not the slowest-moving mattress; some models, like the Nectar Classic, are noticeably less responsive. Still, it adapts quite slowly when you move, which creates a hugging feeling but also makes it harder to move around in your sleep.

This all-foam mattress has very little bounce, which gives it a slightly sluggish feel and makes changing sleeping positions feel more difficult.

The memory foam upper comfort layer has very low resilience. It's slow-moving and doesn't offer much "push back," which is normal for memory foam. The other polyfoam layers are made of more resilient foams, which helps make the mattress a bit bouncier overall. 

The Novaform ComfortGrande Plus has decent edge support. The edges compress when you sit on the very edge, creating a slight ramp that can make you feel like you're sliding off the mattress. If you want a mattress with better edge support, the Sealy Posturepedic Plus Mount Auburn has a significantly better performance and a similar firmness level.

This mattress has nothing built into its edges for reinforcement, and its edge support is just decent.
