Nectar Premier   Review

This mattress uses mostly lower-quality foam. The memory foam upper comfort layer isn't dense enough to be considered good quality, so it's prone to forming indentations sooner compared with higher-quality materials. The polyfoam transition layer is also lower-quality. That said, the support layer polyfoam is just dense enough to be considered good quality, which will help the mattress resist sagging for longer compared with models with lower-quality support layers.

The comfort layer is made of memory foam, which is soft and contouring. There's a firmer polyfoam transition layer, which prevents the heavier parts of your body from sinking too far. A firmer layer of polyfoam below provides support.

This 'Medium' mattress has a fantastic body conformity performance for people in the heavier weight category, whose shoulders will compress it enough to relieve pressure. Its performance is also good for average side sleepers. However, lighter people won't compress it enough for comfortable side sleeping and will likely need a plusher mattress.

The comfort layers are quite enveloping. The upper comfort layer compresses nearly completely without much pressure, so even the lighter parts of you will sink into it. However, its lower layers are firmer, so you don't sink very far. The mattress's upper layers contour closely around you, so most of your body is in contact with the mattress as it molds to your shape, which helps create a more enveloping feel despite its low sinking.

This mattress only provides good support for lighter people. If you're in the lighter weight range, your hips will sink in a little more than your lower back or abdomen, but overall, it provides good support for the heavier parts of your body. While it's also fairly supportive for people in the average weight category, back/stomach sleepers in that weight range may find it's not supportive enough for proper alignment. It provides just passable support for heavier individuals, who will likely need a more supportive mattress, like the Casper Cooling Select, especially for back and stomach sleeping.

It has great cooling. Somewhat surprisingly for an all-foam mattress, it dissipates heat just as efficiently as the Nectar Premier Hybrid, which has a spring support layer. It doesn't feel overly warm when you first get into bed, and it continues to dissipate heat efficiently all night, making it a good option even for hot sleepers.

It has excellent motion isolation. You'll only feel bigger movements nearby, so you'll feel the initial shock in the lumbar area when your partner rolls over, but you won't feel it around your head or feet. Motion also dissipates very quickly, so while you'll feel the initial shock of movement, you'll never feel like the mattress wobbles with every little motion.

The Nectar Premier is a very responsive mattress. It recovers its shape quickly after being compressed, so you don't feel stuck in place.

It's decently bouncy. Although it's an all-foam mattress, it doesn't have a lifeless feel. Its moderate bounciness helps make it feel easier to move around on.

The memory foam upper comfort layer has low resilience, or bounciness. It doesn't 'push back' very much when compressed. This is normal for memory foam, which has a sinking feel and contours around your body closely. The other layers are much bouncier, so they offer more push-back and help make the mattress feel easier to move around on.
