The Mattress Nerd’s Take: The Sweetnight 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.
At Mattress Nerd our firmness scale ranges from 1–10, with 1 being the softest. The Sweetnight 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.
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 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 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.
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.
|Body Type:||BACK SLEEPERS||STOMACH SLEEPERS||SIDE SLEEPERS|
|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
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.
Sweetnight 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 Sweetnight 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.
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.
The Sweetnight 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.
Sweetnight 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.
Sweetnight 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, Sweetnight will repair or replace your Sunkiss for free during the time of this 10-year warranty (minus the cost of shipping).
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? Sweetnight 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:
We think the Sweetnight mattress is good if you sleep with a partner and are easily awoken or if you’re looking for a memory foam mattress that will work with your budget. The Sunkiss won’t be as good if you weigh over 230 lbs or sleep very warm.
Sweetnight 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.
Generally, bed-in–a-box mattresses are ready to go as soon as you let them out. You can sleep on the Sweetnight 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.
The Sweetnight 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.
The Sweetnight Breeze is a plush, soft all-foam mattress, similar to the soft side of the Sunkiss: They both isolate motion well, hot onto body heat, and have poor edge support. I will say, that the Breeze blew the Sunkiss out of the water when it comes to relieving pressure.
The Sweetnight Twilight is a hybrid mattress with a simple construction and low price. These mattresses have very little in common: The Sunkiss is better at isolating motion and supporting side sleepers, and the Twilight is better at responding to your movements and keeping you from overheating.
Zinus has a line of affordable foam and hybrid mattresses, mostly sold on Amazon. Zinus is the more affordable option, but Sweetnight has better quality materials.
Nectar is a bed-in-a-box classic and is a bit more luxurious when compared to the Sweetnight Sunkiss. This all-foam mattress has a removable, washable cover and a 365-night sleep trial period. The Sunkiss is still the more affordable option.
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.
The Sweetnight 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.
