The Mattress Nerd’s Take: The Sweet Night Sunkiss is a flippable, all-foam mattress with a different firmness level on each side: medium-soft and medium-firm. This bed works best for back sleepers and those who sleep in pairs, but it has a hard time keeping you cool and supporting you along the edge.

How Does the Sweet Night Sunkiss Mattress Feel? 


At Mattress Nerd our firmness scale ranges from one to 10, with one being the softest. The Sweet Night Sunkiss has dual-sided firmness, meaning one side is medium-soft (4/10) and the other is medium-firm (6/10).

The soft side will be better for side sleepers and lightweight back sleepers because it hugs your pressure points and allows your body to sink in the right amount. The firm side will be better for back sleepers and light to average weight stomach sleepers because of its ability to keep you elevated.


The Sunkiss is a gel memory foam mattress, so it uses this gel infusion to create a cooling sensation on the surface of the bed. We felt this cooling effect more on the softer side when compared to the firmer side.

This mattress also has two open-cell, breathable foam layers for ventilation. This helps keep body heat from being trapped in the foam. Still, this is not the best option for hot sleepers because it is entirely made of foam, so it naturally traps your body heat more than a bed with coils or a latex mattress. For other options, see the best cooling mattresses.


The Sunkiss uses a layer of gel foam, a layer of comfort foam, and two layers of high-density support foam. What this means is that the mattress is going to be most supportive for lightweight and average-weight people because they will stay in the comfort layers as they lie down.

Heavyweight sleepers may sink down into the support layers, so the mattress won’t perform as intended. If you weigh more than 230 lbs, I recommend a firm mattress made of foam or something with more supportive materials, like pocketed coils.

The edge support on this mattress is less than stellar. It sinks quite a bit when you sit on the edge and feels as if you might fall when you lie there. If you don’t sleep near the edge, this may not be an issue for you, but it does indicate that this mattress may not have great durability when compared to a foam mattress with better edge support.

Back Sleepers

When lying on the Sunkiss on my back, I noticed great body weight distribution on the soft side and no pressure in my low back on the firm side. Lightweight and average-weight back sleepers should be fine on either side–it just depends on your preference. Heavyweight back sleepers, on the other hand, may want to check out our list of the best mattresses for back sleepers.

Stomach Sleepers

Stomach sleepers need a mattress that keeps the hips elevated, so the hips don’t bow down, throwing your spine out of alignment. The firm side of the Sunkiss works best for lightweight sleepers and some average-weight stomach sleepers. If you’re a heavyweight stomach sleeper, your hips will bow down no matter which side you choose; we recommend anything from the best mattresses for stomach sleepers.

Side Sleepers

Side sleepers will most likely do best on the soft side of the Sunkiss when it comes to spinal alignment. It sinks down the perfect amount for lightweight to average-weight sleepers. However, we noticed a ton of pressure buildup in the shoulders and hips on the soft side and less on the firm side

If you are a side sleeper suffering from back pain, choose the soft side. If you are a side sleeper with sensitive joints, choose the firmer side. If you need both or are a heavyweight side sleeper, take a look at our list of the best mattresses for side sleepers.

Combination Sleepers

Responsiveness in a mattress is a key factor for combination sleepers because a responsive mattress allows you to change positions easily. The firm side of the Sunkiss is way more responsive than the softer side: good for lightweight to average-weight combo sleepers.

Remember: foam isn’t as responsive as a latex mattress or a bed with coils, so if you toss and turn often or you are a heavyweight combo sleeper, check out the best mattresses for combination sleepers for more options.

Lightweight (< 130 lbs):  5 4 3
Average weight (130 – 230 lbs): 4 3 3
Heavyweight (> 230 lbs):  3 2 2

1 = Very poor, 2 = Not good, 3 = Fair, 4 = Good, 5 = Excellent

Does It Fit Your Lifestyle?


For all of you folks at home who sleep with a partner, pet, or child, a mattress’s ability to isolate motion can be the difference between a sound night of sleep and waking up every time your partner moves. When we tested the motion isolation of this mattress, we were very impressed.

Using a beaker full of liquid, we dropped a weighted ball onto the mattress to see how much the liquid in the beaker shook. Because of the Sunkiss’s thick foam layers, the liquid barely even moved. When we tested this ourselves by lying on the mattress, it was hard to even tell when our partner got off of the bed: a great sign. These motion transfer tests show the Sunkiss is a great mattress for couples.


Sweet Night offers a series of mattresses at a super affordable price. At Mattress Nerd, we classify any mattress under $1,000 as a budget mattress, and the Sweet Night Sunkiss mattress comes in at about $500 for a Queen size. If you’re on a tight budget, the Sunkiss is a great value option for your bedroom or guest room.

Joint and Back Pain

We don’t want you to wake up in any sort of pain, so let’s examine the Sunkiss’s ability to ease pressure from your back and sensitive joints.

When sleeping on your side, the Sunkiss doesn’t do the best job at relieving pressure points from the shoulders on the firm or soft side, but it does a decent job at relieving pressure from the hips. So we would not recommend this mattress to anyone with shoulder pain.

When it comes to easing back pressure, the firm side of the mattress does a better job. The soft side does a good job with pressure relief for light to average-weight back sleepers. However, heavyweight back sleepers could see some pressure build-up. For more options, see the best mattresses for back pain.

Construction: What’s Under the Surface?

The Sweet Night Sunkiss is an all-foam, flippable mattress. Each side is a different firmness level: medium-soft and medium-firm. The mattress uses gel infusions and prorated foam layers to help keep hot sleepers cool. The memory foam layers in this mattress are CertiPUR-US Certified foams, meaning they should have any harmful chemicals, heavy metals, or formaldehyde.

We broke down this mattress layer by layer so that you can get a good look inside.

Layer #1: Gel-infused memory foam: The top layer of foam uses a cooling gel infusion to move heat away from your body. 

Layer #2: Comfort foam: This comfort layer is ventilated to provide airflow throughout the mattress to help out hot sleepers.

Layer #3: Zoned open-cell foam: The star of the show is the three-zoned layer of foam, which uses varying levels of firmness at three different locations down the mattress to offer your body the right support from head to toe. This layer also uses open-cell foam to allow your body heat to escape.

Layer #4: High-density support foam: The final layer of the Sunkiss mattress uses thick, high-density polyfoam to support your body weight and keep the mattress from sagging.

How Much Does the Sweet Night Sunkiss Mattress Cost?

King $648 76” x 80” 10” 62.92 lbs

How Do the Policies Measure Up? 

Shipping & Unboxing

Sweet Night only ships to the U.S., but the Sunkiss ships free as a bed in a box (unless you live in a remote location) and should be there in seven to 15 days. You can track your order through the link they email you. Sweetnight does not offer white glove delivery at this time.

Because it is a relatively light, all-foam mattress, it only took us about a minute and a half to unbox this bed. We noticed a slight off-gassing smell (sort of like when you open up a new can of paint) which is normal with boxed foam beds. It went away after we aired out the bed for a few hours.


Sweet Night covers your Sunkiss mattress with a 10-year limited warranty. This means if your mattress has any manufacturer defects or defects in the material, splits or cracks in the foam, or sagging greater than an inch and a half, Sweet Night will repair or replace your Sunkiss for free during the time of this 10-year warranty (minus the cost of shipping).

Trial Period & Returns

A sleep trial is what makes online mattress brands stand out: who wants to buy a new mattress without being sure they’ll like the feel? Sweet Night gives you 100 nights to try out the Sunkiss and see if you want to keep it.

If you decide to return it, you must do so during this 100-night trial period in order to receive a full refund. Returns are easy:

  1. Get in contact with customer service to request your return.
  2. Provide proof of purchase.
  3. Return the mattress to Sweetnight.
  4. Receive your refund one to two days after Sweet Night receives your return.

Sweet Night Mattress FAQs

Is Sweet Night a good mattress?

We think the Sweet Night mattress is good if you sleep with a partner and are easily awoken or if youu2019re looking for a memory foam mattress that will work with your budget. The Sunkiss wonu2019t be as good if you weigh over 230 lbs or sleep very warm.

Where are Sweet Night mattresses manufactured?

Sweet Night mattresses and their materials are made in China. The cover uses rayon cotton fabric that is hypoallergenic and resistant to dust mites. The rest of the mattress is made with high-quality foam.

How soon can I sleep on my Sweet Night mattress?

Generally, bed-in-a-box mattresses are ready to go as soon as you let them out. You can sleep on the Sweet Night as soon as it finishes expanding. If there is off-gassing, I recommend that you let your bed air out until the scent dissipates before sleeping on your new mattress.


Comparing the Sweet Night Sunkiss Mattress

Sweet Night Sunkiss Mattress vs. Sweet Night Island Mattress

This mattress is no longer available for purchase. To help you find your next mattress, check out our list of the best mattresses available on the market now.

The Sweet Night Island is a hybrid mattress that features individually wrapped coils as the primary support core. The coils means it will work better for heavyweight sleepers and hot sleepers when compared to the Sunkiss. However, the Sunkiss mattress isolates motion better for couples and co-sleepers.

Sweet Night Sunkiss Mattress vs. Sweet Night Breeze Mattress

This mattress is no longer available for purchase. To help you find your next mattress, check out our list of the best mattresses available on the market now.

The Sweet Night Breeze is a plush, all-foam mattress that’s similar to the soft side of the Sunkiss. Both beds isolate motion well, but have poor edge support. If you’re a side sleeper or have joint pain, keep in mind that the Breeze blew the Sunkiss out of the water during our pressure relief test.

Sweet Night Sunkiss Mattress vs. Sweet Night Twilight Mattress

This mattress is no longer available for purchase. To help you find your next mattress, check out our list of the best mattresses available on the market now.

The Sweet Night Twilight is a hybrid mattress with a simple construction and low price. These two mattresses have very little in common. The Sunkiss is better at isolating motion, and the Twilight is better at responding to your movements and keeping you from overheating.

Sweet Night Sunkiss Mattress vs. Zinus Mattress

This mattress is no longer available for purchase. To help you find your next mattress, check out our list of the best mattresses available on the market now.

Sweet Night Sunkiss Mattress vs. Nectar Mattress

This mattress is no longer available for purchase. To help you find your next mattress, check out our list of the best mattresses available on the market now.

Nectar is a bed-in-a-box classic. This all-foam mattress provides better pressure relief and motion isolation than the Sweet Night Sunkiss, plus it has a 365-night trial period and Lifetime warranty. The Sunkiss is still the more affordable option, though.

Sweet Night Sunkiss Mattress vs. Casper Mattress

This mattress is no longer available for purchase. To help you find your next mattress, check out our list of the best mattresses available on the market now.

Casper is another all-foam mattress that comes in a box. What makes Casper stand out is their Zoned Support system that creates near perfect spinal alignment for side sleepers. It is more responsive than the Sunkiss, but the Sunkiss isolates motion better.

  • Flippable: With this bed, you get both a soft feel and a firm feel. If you’re not sure which one you like better, all you have to do is flip.
  • Budget friendly: If you’re on a budget, but want a relatively well-performing foam bed, the Sunkiss has your back with great pricing.
  • Great for couples: Sleeping with a partner can lead to sleepless nights. The Sunkiss helps by isolating motion better than hybrid mattresses.


  • Not many sizes to choose from: The Sunkiss only comes in four sizes: a Twin size, Full size, Queen size, and King size mattress. If you’re looking for a Twin XL or a California King, you may have to look elsewhere.
  • Not supportive enough for heavy people: The foam layers in the Sunkiss are cozy and isolate motion well, but they won’t provide enough support for heavyweight sleepers.
  • Subpar edge support: If you find it most comfortable to sleep near the edge of the bed or need some space from your sleep partner, you may want to look for a mattress with reinforced edges.

What’s the Bottom Line?

The Sweet Night Sunkiss is best for lightweight and average-weight back, stomach, and side sleepers. Couples shouldn’t see too much motion transfer across the surface, and it doesn’t hurt that this bed is very friendly for your wallet. However, if you sleep hot or weigh over 230 lbs, you may not love the Sunkiss as much as others.
