My Review of the Sweetnight Gel Memory Foam Mattress

A few years ago, my husband and I decided we needed a guest room in our house for when our parents come to visit from out of town. We had a spare room and a few furnishings, but we still needed a mattress for the room. We love our parents and wanted to get the most comfortable mattress possible—for a reasonable price. After many hours of research, we settled on the Sweetnight 10-inch gel memory foam mattress.

The price of this mattress was absolutely amazing for being a gel memory foam mattress. We had purchased a Purple brand mattress for almost double the price, and I was excited to find out how this mattress stacked up. This mattress is made in China, so would it feel like a quality mattress, or would we be left regretting our decision to buy such an inexpensive mattress?

We bought it on Amazon, got it in two days, and spent a week sleeping on the mattress to try it out. Here’s every detail on the Sweetnight mattress.

The Features of the Model We Picked

We settled on the Sweetnight 10-inch gel memory foam mattress. These are the main features of the mattress, some of which are fairly unique for a mattress-in-a-box:

  • Two Sleeping Surfaces: This mattress is flippable, so that means there is a plush and a firm side to this mattress. You can choose to sleep on either side.
  • Multi-Layered Support: The top layer is supposedly a two-inch-thick layer of gel-infused memory foam. The second layer is a five-inch thick layer of high-density supportive foam (more like traditional memory foam) and the bottom layer is a three-inch support foam. That means there are about seven inches of overall comfort memory foam-like material in this mattress, which I was very impressed with. Most mattresses only contain three or four inches of total memory foam.
  • CertiPUR-US Certified: The company advertises that the foam in this mattress is made without any harmful substances (like formaldehyde, mercury, and other heavy metals).
  • Hypo-Allergenic Mattress Cover: The mattress cover is removable, hypo-allergenic, breathable, resists dust mites, and resists bacterial growth. In case you didn’t know, bacterial growth is what can cause your mattress to smell bad or have unexplained stains. It feels like a quality cover that is made of a pleasantly soft material. It’s not “plastic feeling” at all, more of a soft cotton feeling.
  • Unique Memory Foam Behavior: The memory foam in this mattress is supposed to be cool for sleeping, resist sagging or roll-off issues, self-adjusting to body weight, and be a solution for back pain and frequent partner movements.

UPDATE: Sweetnight has now released a new version of this mattress. It features a thicker gel memory foam layer (at three and a half inches) and air-flow comfort foam to help keep you even cooler. Check out Sweetnight's new version of this mattress.

As promised, the Sweetnight mattress arrived at my door within two days of ordering it on Amazon.

Part 1: My Opinions of the Mattress

I have a self-admitted issue of over-researching things. Like with everything I buy online, I researched this mattress to death before buying it, but no matter how much you research you never can actually tell what a mattress feels like until you get to feel it in person. That’s the scary thing about ordering a bed online.

I do love the convenience of ordering a “mattress-in-a-box,” but I will say that the classic mattress store does have one huge advantage; being able to feel the mattress before ordering. That’s why I think the best thing I can do to help you make your decision is to do my best to give you as much detail as possible about what the mattress feels like so you can feel almost like you’ve tried it.

The Feeling of the Soft Side

The soft side of this mattress really isn’t incredibly super soft. I would call it closer to medium firmness. It does feel pleasantly plush in the sense that you do sink in slightly (about an inch or so) and it takes a few seconds for your body to “settled in” once you lay down. Of course, a pillow topper can always be added to increase the plushness.

I’m a side sleeper and usually need a fairly plush mattress. My husband is a stomach sleeper and although he likes a bit firmer mattress than I do for that reason, he still enjoys a bit of a soft feeling. We both enjoy the soft side of this mattress the most. Although it was slightly firmer than we expected, it was still plenty plush and extremely comfortable.

It’s important a new buyer knows though that the soft side is advertised as “plush” but it might be slightly firmer than some expect. We still both really love how comfortable the gel memory foam is on this side. The slight sinking feeling does suck you in a bit and makes you want to fall asleep immediately, which is fantastic. You can definitely tell there is a slight “gel” feeling to the memory foam which makes it quite pleasant.

It really feels like a high-end Tempurpedic type memory foam mattress (those, by the way, sell for many thousands of dollars). This side of the mattress does not at all feel cheap and feels like true high-end memory foam. Honestly, it’s incredibly comfortable for both of us.

The Feeling of the Firm Side

Flipping the mattress over reveals the firmer side, which Sweetnight says you can also sleep on. This side is, in fact, significantly firmer than the plush side. You sink in slightly, but it’s definitely obvious that this side doesn’t consist of the gel memory foam. On this side, you’re basically laying on the harder “support foam” bottom layer.

When I lay on this side, I can definitely tell I’m laying on standard foam and not memory foam. It does have that feeling of sleeping on a chunk of normal foam and feels a tad cheaper. It’s not a particularly amazing feeling, but if you like a firmer mattress, I suppose it could work. It’s significantly firmer, I’d say in the area of 50% to 75% firmer than the plush side.

Even though we won't be using this side, it is nice to know that it is an option to make the mattress firmer with a simple flip of the mattress.

Unpacking the rolled up mattress wasn't too difficult, but it doesn't hurt to have a second person to help position the 64 pound mattress.

Too Hot or Too Cold?

After a week on the mattress, neither my husband nor I have any complaints about the temperature. Each side is a little different as far as temperature and breathability, so here’s the breakdown.

The Soft Side

The soft side is definitely breathable and neither my husband nor I ever felt too hot during the night or got sweaty. I usually don’t get hot at night so that's not surprising for me, but my husband almost always gets hot. He said he had no issues with getting too hot on this which was pretty amazing to me. This side is great if you are a hot sleeper like he is.

The Firm Side

The firmer side, which is not true memory foam, did not seem to be near as breathable as the gel memory foam (plush) side. Both my husband and I had issues getting sweaty and hot on the firm side of the mattress. It wasn’t horrible for me; I just got slightly warm during the night. However, my husband complained about flipping all night long to let the side of his body that was touching the mattress cool off.

Edge Support

This mattress doesn’t have any type of separate material along the edges to bolster edge support. Frankly though, almost no quality mattresses these days do and in my mind, that would be a sign of a cheap mattress.

This mattress seems to feel just fine on the edges. The mattress does a great job of keeping its shape and doesn’t slope off in any way near the edges. Frankly, compared to the Purple brand mattress we own, the edges on this mattress feel significantly better. The edge support for the soft side and firm side of the mattress was about the same.

Off-Gassing Concerns

Like with any new large product I get, especially a mattress, I am fairly concerned about off-gassing. I have done a lot of research on this in the past and as far as I can tell, there is not a scientific method for measuring levels of off-gassing I can do at home. At least no other method than just using plain old sense of smell.

I have noticed that just about any mattress in a box (I’ve owned quite a few now) will have a considerable amount of that strong glue/plastic/new-product smell when it’s first opened. This is partially because they’re packaged up almost immediately after production, compressed, and vacuum sealed. So it really can’t air out during delivery, while sitting in a warehouse, or in the backroom of a mattress store.

Even though it was somewhat expected, this mattress did seem to have a very strong smell, stronger than other mattresses I’ve owned. Here’s what I noticed each day after unpackaging.

  • Day 1: A very strong smell was very noticeable throughout the room. I never felt light-headed, but I did feel an urge to open a window and wasn’t very excited about sleeping on it that night so we left it in the spare room to air out.
  • Day 2: Still fairly strong-smelling; still kept a window open in the room.
  • Day 3: The smell had gotten a bit more subtle and I felt ok closing a window.
  • Day 4: Smell was reduced even further.
  • Day 5: I finally felt comfortable sleeping on the mattress by day 5, although the smell was still noticeable.

Each subsequent day the odor got less intense and by day 10 I couldn’t detect any smell without burying my nose in the bare mattress. In my mind, that means it was gone completely by day ten.

As I said, it’s to be expected that these “mattresses-in-a-box” will off-gas significantly, but this mattress did seem to smell fairly strongly for quite a few days. If you decide to get this mattress, I would plan to let it air out in a separate room for a few days (a week would be even better) before sleeping on it.

The box had this felt envelope, setup instructions, warranty card, and a sleep journal.

Part 2: Mattress Options, Shipping, and Guarantees

How much a company stands behind their product and supports their customers is becoming incredibly important in recent years. Every mattress company has slightly different return periods, warranties, and options on the variations of the mattresses they offer. I got well versed on this company before ordering and learned even more after ordering.

Mattress Options

Sweetnight offers both a gel memory foam mattress (which is the one we got) and a hybrid mattress. The hybrid mattress consists of both gel memory foam and a coil-based support system. The hybrid version is not flippable. It’s called a hybrid because it's a hybrid between a memory foam mattress and a traditional spring-based mattress.

Sweetnight offers the following mattress configurations:

  • 8-inch thick gel memory foam flippable mattress.
  • 8-inch thick hybrid, non-flippable mattress.
  • 10-inch thick gel memory foam flippable mattress.
  • 10-inch thick hybrid, non-flippable mattress.
  • 12-inch thick gel memory foam flippable mattress.
  • 12-inch thick hybrid, non-flippable mattress with a plush pillow top.

All common mattress sizes are available including cal-king, king, queen, full, and twin. The mattresses work with all types of bed frames including platform, slat, box spring, adjustable beds, and even hospital beds.


I decided to order my Sweetnight mattress through Amazon. It was guaranteed to be at my home in two days, which still is impressive to me considering it’s a mattress. The shipping weight of the queen-size mattress was 72 pounds. The box it was shipped in was a convenient size that my husband was able to navigate up the stairs and through multiple doors without a problem. The box was 20” x 19.5” x 33.5” high.

Inside the box was a nice felt envelope. This contained instructions for unpacking, a warranty card, and a bright yellow sleep journal. They say you are supposed to hold onto your warranty card in case you need to use the warranty down the road. I stapled my receipt to the card and filed it away.

The mattress itself was rolled up tightly and compressed in clear plastic. This was inside a woven plastic sack and inserted into the box. The mattress itself weighs 63.6 pounds and it wasn’t too difficult for my husband to get out of the box and laid onto the box spring.

Once you cut it open, you can watch it inflate almost immediately. The instructions say to give it three days to fully expand but it really seems like it expands completely in just a few minutes. Many reviewers say that after 24 hours it’s basically ready to sleep on.

Return Period

Customers are given 30 days to try out the mattress and send it back if it is not to their liking at no charge. This is fairly standard for items ordered on Amazon and really doesn’t stand out to me as exceptional in any way. It is good to know that there’s a risk-free trial period though and return shipping will be arranged for you. They’ll ship it back even though there is no chance you’ll be able to compress it back into the original box it came in. They’ll just take it fully uncompressed and as-is.


Sweetnight guarantees their mattresses for 10 years from the date of purchase. The warranty covers defects in workmanship or materials. The company states they will either repair or replace the mattress (at their discretion).

They will cover it in the case of any lasting body impressions in the mattress or sagging greater than 1.5 inches. They’ll also cover any physical flaw causing splitting or cracking despite normal care and use. For all the details on their warranty and what it covers, have a look at Sweetnight’s 10 Year Warranty Information Card.

We didn’t have any issues at all with our mattress, but from what I’ve seen on the Amazon reviews, most customers who contacted the company due to any issues received a very fast response from the company. This is a great sign. They have also typically reported a very fair resolution to any issues they’ve had. In my opinion, how a company takes care of their existing customers tells a lot and I’ve seen nothing but good comments about Sweetnight’s customer service from their customers.

I was pleasantly impressed with the quality of this mattress, especially when you consider its very low price.

Part 3: Final Thoughts

We are very happy with this mattress and frankly, for the price, it’s really hard to beat. At the time of this article, the queen size mattress is in the mid $400 range and the king size is in the mid $500 range. This makes it one of the cheapest mattresses I have tried and honestly, one of the most comfortable.

The plush side is great, and I rarely feel my husband flipping or rolling over during the night. Even though I’m largely a side sleeper and he is a stomach sleeper, we both found the soft side of this mattress to be extremely comfortable. The mattress works well with both regular and deep pocket sheets which I was very happy about.

We have since had our parents over and the feedback we’ve had has been overwhelmingly positive. In fact, my mother told me that she hasn’t slept that well in years So, I’d say that means this mattress was a success! Especially when you consider the price of the mattress.

They even offer a matching Sweetnight pillow, which we've tried and like just as much as the mattress. Although it isn't completely necessary if you already have a quality pillow.

My husband and I paid almost double the price for our Purple mattress. Is the Purple mattress twice as comfortable? I hate to admit it, but definitely not. If I had known about this mattress before getting my Purple mattress I would have definitely thought twice and probably ended up with a Sweetnight. Actually the Sweetnight just feels higher quality than the Purple mattress, which is not at all what you’d expect at this price.

Is It Worth Buying?

So if you are looking for a mattress that you can really love, will provide you with a great night's sleep, feels like a high-quality memory foam mattress while at the price of a low-end mattress, this just might be a perfect fit for you. To see the current pricing on this mattress check the Amazon listing about half way down this article. While writing this review, I notice the price dropped by almost $100 from where I bought it at.

Just make sure you stick it in a separate room for a few days so it can air out since the off-gassing smell is the only big drawback. But that’s temporary and easily resolved with a little patience. After that, I am convinced you’ll be very happy with your purchase. We sure are!
