Serta Perfect Sleeper Innerspring  Mattress Review

This is a thick 14-inch mattress, so you might need to use deep-pocket sheets.

This 'Medium-Plush' mattress is best-suited for average and heavier side sleepers as well as lighter back and stomach sleepers. However, its pressure relief isn't good enough for lighter side sleepers. On the other hand, it's not supportive enough for average or heavier individuals who sleep on their back or stomach.

The Serta Perfect Sleeper Innerspring has the best body conformity performance for average and heavier sleepers. It offers fantastic body conformity for heavier individuals, who will compress it enough to effectively relieve pressure when sleeping on their side. Its performance is also excellent for average people, so while you'll feel a little more pressure on your arm and shoulder, it's still well-suited for side sleeping. Unfortunately, its body conformity for lighter people is mediocre. Despite its 'Medium-Plush' firmness level, lighter people won't sink in enough for comfortable side sleeping.

This mattress only offers good support for lighter people. If you're in the lighter weight category, it'll keep your hips well-supported and your spine aligned when you're sleeping on your back or stomach. However, its support for average and heavier people is just passable. It won't do a good job of keeping your spine aligned if you sleep on your back or stomach.

It's decently bouncy, allowing it to avoid the completely static sensation of some all-foam mattresses without having an extremely lively, springy feel. This moderate bounciness helps make changing sleeping positions feel easier than on less bouncy models.

This mattress has a very enveloping feel. Your whole body will sink into its soft, quilted layer, which contours closely around you. This creates a hugging feel that helps with pressure relief, while also creating a sensation of being more 'in' your mattress.

It recovers its shape extremely quickly after being compressed, so you don't feel restricted or stuck in place.

Its motion isolation performance is just okay. You'll feel even smaller movements across the mattress. Movement in the lumbar area is slow to dissipate, which can make it feel like the mattress is wobbling after every movement. If you prefer a hybrid with better motion isolation, consider the Nectar Classic Hybrid or the DreamCloud Classic Hybrid.

It stands out for its fantastic edge support. Even compared with pricier options like the Stearns & Foster Lux Estate, its edges hold up very well when you sit or sleep on the side of the bed. This makes it easy to get out of bed, especially if you have mobility issues, and allows you to sleep on the very edge without feeling at risk of sliding off.

It has good cooling. While it's not the most cooling mattress, it shouldn't make you feel overheated overnight if you don't usually sleep hot. However, it's not cooling enough for hot sleepers. Compared to some mattresses, it feels warmer during the first hour or so as you fall asleep, with somewhat better cooling performance over the course of eight hours. However, if you regularly sleep hot, you may prefer a more cooling mattress, such as the Saatva Classic (Plush Soft).

This mattress has firm polyfoam built into its edges, which contributes to its fantastic edge support.

The quilted top layer is made of polyfoam and fiberfill and is soft, allowing you to easily sink into it. The next layer of polyfoam is firmer and bouncier. Below it is a layer of memory foam, which helps with contouring and adds plushness but doesn't create a slow-moving memory-foam feel since it's below more resilient layers. The transition layer of polyfoam is the firmest foam, helping to prevent you from sinking into the springs.

Most of the foam layers are made of low-quality foam, including the memory foam lower comfort layer and polyfoam transition layer. There are a couple of different foams used in the quilted layer. The white foam comprises most of the layer and has a density of 20 kg/m³, while the yellow foam has a slightly lower density of 19 kg/m³; however, neither is dense enough to be considered of good quality. While the upper comfort layer is made of high-quality polyfoam and will resist forming permanent indentations for longer, the rest of the layers aren't as durable, which may lead to body impressions or sagging sooner than mattresses that use higher-quality materials.

The mattress has about six inches of foam above its pocket coil layer. The lower comfort layer of memory foam is just 1" thick, and since it's below nearly four inches of more responsive foam and fiber fill, including 2" of medium-firm polyfoam, you don't get the sluggish feel of memory foam.

This mattress features pocket coils for its support layer, which generally provides better contouring compared to other types of coils. The springs in the lumbar region are a lower gauge than the others and add some firmness in that area, which can help keep your hips from sinking further into the mattress. Here are both types of springs side by side.

The quilted top is soft, so you'll easily sink into it. The upper comfort foam is medium-firm, with a layer of soft memory foam underneath, so if you compress the polyfoam, it'll allow heavier parts of your body to sink further. The transition layer of polyfoam above the springs is much firmer, which helps avoid you feeling the springs if the foam layers above are compressed.

The lower-gauge springs in the lumbar area are firmer, which can add support to your hips. The springs are all quite soft, which helps explain the mattress's overall medium-plush feel.

The quilted top and polyfoam upper comfort foam are quite resilient, or bouncy, which contributes to the mattress's bounciness. The memory foam lower comfort layer isn't very resilient, which is typical of memory foam, as it's usually contouring and soft but not bouncy. The firmer transition layer below has a medium amount of resilience.

The springs have a lot of bounce, which helps give the mattress its moderate bounciness.
