SweetNight Prime Gel Memory Foam Mattress Review Breakdown

SweetNight Prime is a flippable bed with a soft and firm side. Regardless of how you orient your mattress, both sides have top and bottom memory foam layers surrounding interior sections of layers of foam stacked in a Contouring Curve Design. All SweetNight Prime Foams are CertiPUR-US certified, meaning they are free from pollutants and harmful chemicals.

The cover

The SweetNight Prime Mattress starts with a breathable, high-density, anti-pilling, and anti-slip knitted fabric cover. This temperature-regulating surface will keep you resting at a perfect temperature for deeper and longer uninterrupted sleep.

Cooling gel-infused memory foam layer

This layer is made of a cooling gel memory foam engineered to mold to your body to disperse excess body heat for a cooler and more comfortable sleep.

Pressure-relieving foam layer

This layer is designed to respond to your body shape, heat, and movement. It remains static as you change positions in bed and relieves pressure by evenly distributing your weight over the mattress at a continuous low pressure. This makes SweetNight Prime a good mattress for back and stomach sleepers.

Zoned Open cell comfort foam layer

This unique layer comprises different curved memory foam layers stacked together to create firmness zones throughout the mattress. It is designed to keep your spine correctly aligned, irrespective of your preferred sleeping position.

Here, you’ll also find the support core of both sides of the mattress. This layer prevents you from sinking deep into the soft side of the bed when you flip your mattress.

Mattress Feel and Firmness

When looking for a new mattress, it’s always wise to consider a bed’s feel and firmness. These factors have a significant impact on whether your mattress will feel comfortable and suit your preferred sleeping position.

SweetNight Prime mattresses represent SweetNight’s commitment to bringing modern sleep solutions to modern sleepers. Most gel memory foam mattresses today only offer up to two firmness options.

Mattress Feel and Firmness

With the SweetNight Prime mattress, you’ve got four levels of dynamic firmness to choose from: soft, firm, medium-soft, and medium-firm. It features an innovative Contouring Curve Design that allows you to enjoy your desired firmness level by just flipping or rotating your mattress. This unique design has different high-density curved memory foam layers stacked together to create dynamic firmness zones that accommodate different sleeping positions.

The soft side should allow sleepers to sink further into the sleeping surface and have more of that classic and hugging memory foam mattress feel. The firm side, on the other hand, should make you feel like you’re lying on top of the surface.

Mattress Performance

This bed’s performance depends on your unique specifications and needs as a sleeper, such as your body weight, preferred sleeping position, and whether or not you suffer from chronic pain. Generally, the gel-infused memory foam layers in the SweetNight Prime Mattress work harmoniously to give you a cool, restorative sleep throughout the night.

Pressure Relief

The SweetNight Prime Mattress has a high-density gel memory foam comfort system that results in excellent pressure relief. The soft foam layers between the mattress conform closely to your body shape, cushioning pressure points at the back, hips, and shoulders. This benefits the side and lightweight sleepers, as the layers relieve tension and minimize aches and pains.

The firm side of SweetNight Prime Mattress is better for stomach and back sleepers weighing more than 130 pounds. This side of the bed gently contours to your body but has a thinner comfort layer and a firmer surface. So you won’t have to worry about the aches associated with saggy, uneven mattresses.

SweetNight Prime Performance for Couples

If you sleep with your partner, you’ll want to consider additional factors like edge support, cooling, motion isolation, and whether or not your bed is suitable for sex.

Edge Support

Edge support measures whether or not the edges of your mattress are strong enough to support you when you sleep on them or roll toward the edge of the bed.

Memory foam beds often lack edge support because they don’t have reinforced perimeters. However, the high-density and curved foam layers offer better-than-average support than other all-foam mattress models.

Individuals weighing less than 230 pounds are more likely to receive sufficient support when sleeping on the soft and medium-soft sides. Heavy sleepers, on the other hand, may notice sagging around the edges when moving in and out of bed. These sleepers will be better off sleeping on the firmer side of the mattress.


Generally, two people sleeping on the same bed overheat more quickly than one, so purchasing a cooling mattress is vital for couples and hot sleepers.

Most memory foam SweetNight mattresses retain body heat to some extent. SweetNight crafted their Prime beds to be more temperature neutral than traditional memory foam. Like the SweetNight Twilight Mattress, this model is very cooling thanks to its gel-infused memory foam, which promotes airflow throughout the sleep surface.

It also features a breathable jacquard cover which aids in dissipating heat and moisture from the sleeper’s body. Lastly, the SweetNight Prime Mattress boasts air-cell technology, which provides you with an incredibly cool and comfortable sleep if you're a hot sleeper.

The unique nature of this technology allows air to flow freely in and out of your mattress, eliminating hot spots and promoting thermo-regulation. This keeps you warm in winter and cool in summer.

Remember, your mattress isn’t the only factor when it comes to temperature regulation. The bedding, bedroom temperature, and sleepwear you choose also affect how cool or warm you feel overnight.

Motion Isolation

Motion transfer is the body movement noticeable from one side of the mattress to the other. It’s crucial for couples as it shows whether you’ll feel your partner’s night movements from their side of the mattress on your side.

Memory foam mattresses usually absorb impact from movement, and the SweetNight Prime Mattress is no exception. Like the SweetNight Sunkiss Mattress, the Prime model prevents motion from transferring across the bed so that everyone enjoys the good night’s sleep they deserve.

The softer side of the mattress has a high-density foam and a softer transition foam layer. These layers isolate motion exceptionally well. You shouldn’t feel your partner’s movements during the night, resulting in fewer sleep disturbances.


Hybrid mattresses like the SweetNight Dreamy Hybrid bed are generally more suitable for intimate activities than the conforming Prime model. The bounce of the individually wrapped coils facilitates movement, which is perfect for changing positions.

However, the SweetNight Prime Mattress is a virtually silent bed which is a plus during sex. Unlike hybrid and innerspring mattresses that may squeak, this mattress shouldn’t produce any sounds in response to body movement. And, if you and your partner prefer softer mattresses for amorous activities, the medium soft side of the Prime model should be suitable.

Ease of Movement

Because SweetNight Prime is an all-foam mattress, it doesn’t offer the easiest sleep surface to move around in. When you lie on the surface, the gel memory foam hugs your body. When you move, an impression of your body remains on the mattress for a period of time, which can inhibit movement.

Innerspring, latex, and hybrid mattresses bounce back faster than all-foam beds, making movement easier. They’re springier mattresses that don’t conform to the sleeper’s body. If you don’t enjoy the “hug-feel” of traditional memory foam, you may opt for a hybrid model such as the Twilight Hybrid Mattress.

Sleeper Types and Body Weight

Sleepers of different body weights and sleeping postures will experience the SweetNight Prime Mattress differently. Let’s look at how this SweetNight mattress will feel for side, stomach, and back sleepers.

Side Sleepers

Generally, side sleepers may feel pressure build-up at their hips and shoulders, especially if their bed is too firm. You’ll be glad to know that the conforming feel of the Sweetnight Prime Mattress relieves pressure in these areas. It is responsive, meaning it reacts proportionately to pressure build-up for side sleepers and keeps their spine aligned.

The soft side of the bed is ideal for side sleepers who weigh 230 pounds or less. The cushioning memory foam is beneficial for the hips and shoulders, while the high-density foam keeps the spine aligned. However, this side of the bed may be too soft for heavier sleepers (those who weigh 230+ pounds), as they’re more likely to sink into the surface excessively.

The firm side provides excellent support for side sleepers weighing more than 230 pounds. The firmness of the surface is more supportive than the soft side, and memory foam’s comfort layer contours more moderately.

Stomach Sleepers

Stomach sleepers need a firmer mattress to support their abdomens and hips, especially if they carry more weight around these regions. The firm and medium-firm side of the SweetNight Prime Mattress is supportive enough for stomach sleepers.

The soft side is suitable for stomach sleepers who weigh 130 pounds or less. This firmness cushions the chest and shoulders while supporting the lower half of your body. Those weighing more than 130 pounds may find this side uncomfortable and less supportive, as they may sink into the surface too much.

Back Sleepers

Back sleepers are highly likely to maintain a neutral position as they sleep. These sleepers benefit from conforming mattresses that relieve pressure and support the lower back. With four firmness alternatives that suit different body types, this SweetNight mattress is a perfect pick for back sleepers.

Its soft side is ideal for back sleepers weighing less than 130 pounds. These individuals won’t sink into the surface excessively as the memory foam will support their lumbar region and contour to their body shape. Back sleepers weighing more than 130 pounds can press into the soft curved layers too much, which may lead to spinal misalignment.

If you weigh more than 130 pounds, you should consider sleeping on the firmer side instead. There’s enough contouring on this side for lumbar support and pressure point relief. You can also opt for the SweetNight Breeze Mattress. It features a triple-layered foam design and a supportive alignment technology that allows your joints, muscles, and back to rest as you sleep.

Closing Thoughts

It’s the best pick for sleepers who aren’t sure what mattress firmness level they need, as they can choose what best suits them by simply rotating or flipping the bed.

The unique curved foams used in the comfort layer of this mattress offer the traditional memory foam feel of contouring and body hug without making you sink deeply into the surface.
