Who is the Sweetnight mattress for?

If you are looking for an affordable hybrid mattress then the Sweet night mattress is definitely an option that you must consider. 

Hot sleepers and those who frequently change their sleep position during the night will also find this mattress suitable. 

Generally, it is suitable for all sleep positions if you weigh less than 100 kg. Although it depends on which thickness you choose, because it is available in the following sizes – 20, 23, 25 and 30 cm, or 8, 9, 10 and 12 inches.

What do we use this product for?

We use this product to make us comfortable while sleeping, whether we are almost always in just one sleep position or we often twist and turn. Also, we use it because of the motion isolation which is good, so it is suitable for couples and because of the temperature control. This mattress is an ideal pick for:

Features you should know about the Sweetnight mattress

Since the mattress is the biggest and most important thing for a good night's sleep, we believe that there is a plenty of features you should know about the Sweet night mattress.

Wrapped pocketed steel coils

If we look from the bottom to the top, the first of the five layers of this mattress makes wrapped pocketed steel coils. It is important to say that all steel coils are individually wrapped, which significantly affects performance.

Therefore, each coil is able to work individually and support your body no matter how many times you change your sleep position during the night. Also another advantage of individually wrapped coils is motion isolation because in this case there is no transfer of motion from one coil to another. So you will not feel the movement of your partner.

Pressure relief

Although the Sweet night mattress is a bit firmer than the industry average, the pressure relief is good. On a firmness scale of 1 to 10, we would say that this mattress is around 7, which classifies it as a medium firm mattress, but closer to a firm than a soft one. Anyway, you will sink into it just enough to feel the pressure relief without sinking too much so you can't move easily.

This firmness is the right choice so that this mattress can be used by back, side and stomach sleepers, with sufficient pressure relief. Of course there are mattresses where the pressure relief is even better but those models are not suitable for all sleep positions.

Motion transfer-free

We have already mentioned motion transfer, but we will say something more about that feature. Individually wrapped coils prevent vibrations very well and that is why in most cases you will not feel that someone is sleeping next to you at all. However, in the moments when your partner gets out of bed, for example, you can feel some amount of motion.

Innerspring + foam

In addition to the innerspring layer, this mattress also has three layers of different memory foam. After individually wrapped steel coils comes a layer of high-density memory foam that gives firmness to the mattress. Although it is high-density, breathability is excellent. Then in the middle of this mattress a gel memory foam is placed to make you as comfortable as possible, and also for support. Gel infused memory foam is a great buffer so you don't feel coils. And finally comes another layer of high-density foam for support.

CERTI-PUR quilted knit top cover

Finally, the closest to your body is the quilted knit pillow top cover. This cover is more than just protection for you mattress. It contains another thin layer of gel infused memory foam for comfort and pressure relief. In addition, the cover will not cause skin irritation, and it is also cooling. 

The cover is CertiPUR-US certified which tells us that it is free of harmful substances like formaldehyde, Mercury, and other heavy metals. Also, the textile used for cover is OEKO-TEX certified which is another well-known certificate concerning product safety.

10 years guarantee

Sweetnight mattress comes with a 10 year guarantee which is mostly common for mattresses, but is great considering it is affordable for a hybrid mattress. It is a limited warranty, which means that your mattress will be repaired for free or that you will get new one in case there are defects related to the material, then noticeable sagging and the like. Of course, if the damage is the result of misuse or mishandling then it is not the fault of the company and therefore the guarantee is invalid.

Rolled and packed in a box

The mattress arrives at your address rolled and packed in a box. It is firstly compressed so as not to be damaged in the packing process, and then rolled and shipped to your address. Once you unpack it, you will have to wait 2 to 3 days for it to regain its original shape.

Review of the Sweetnight mattress

an image of a woman pressing the sweetnight mattress

Sweetnight mattress is a hybrid mattress of medium firmness. You can choose between 4 different thicknesses, and which one you choose depends on your body type and sleep position, as well as your preference. The mattress consists of 5 layers, 1 layer is made of steel coils, and the rest are different types of memory foam which makes it more versatile than some gel memory foam mattress.

The cover is also filled with memory foam. Although it has two layers of high-density memory foam, breathability is great and is therefore a great choice for hot sleepers. It comes with a 100-day risk free trial period and a 10 year limited warranty.


  • Type: Hybrid
  • Firmness: 6/10
  • Thickness: 20, 23, 25, 30 cm
  • Sizes: Double, King, Single, Small Double, Super King.
  • Warranty: 10 years

Check the alternatives to the Sweetnight mattress

If price does not play an important role in your decision, then as an alternative to the Sweet night mattress, we suggest Simba Hybrid mattress.

Simba Hybrid Mattress

If you've decided that a budget-friendly mattress isn't your speed after all, we strongly suggest taking a look at the Simba Hybrid Mattress. While it's more expensive it's also magnitudes more advanced when it comes to comfort and support!

Each layer on this mattress has a specific role- and there are six of them. That is why it is equally comfortable and supportive. 

It adapts perfectly to your movements, and you also don't have to worry about your partner feeling you as you move, because the motion isolation is great.

It is completely free of all chemicals harmful to you and our environment. So, it's also an excellent choice for environmentally conscious sleepers.

In addition, it is a great choice for hot sleepers thanks to a cooling gel that prevents you from getting hot. So, as you can see, it has most areas completely covered!

What makes this product better than some other similar ones?

We did not find any single feature that makes this product better than some other similar ones, but we would rather say that overall it is very good and affordable for a hybrid mattress of such quality.

How did we test the product?

an image of a woman laying down on a bed

You get free delivery if you choose standard delivery and your mattress should arrive within a few working days. There is also the option “Mattress Recycling” where in addition to removing your old mattress and taking it for recycling, they will bring your new Sweetnight mattress to room of choice.

You need to provide space without obstruction to bring in a new and remove the old mattress. And keep in mind that if there is no elevator in your building, and you live on the third floor for example, then it will not be delivered to the room of choice.

We have already mentioned that it will be delivered compressed and rolled, so you will have to wait about 72 hours before using it. In addition to taking so long to regain its shape, it takes about as long for the chemical odour to disappear, so you would definitely have to wait that long even if it wasn't delivered compressed.

The mattress looks good and we did not find any visible flaws after we examined it in detail. The cover is very soft to touch and we expected it to be comfortable sleeping on it, which was confirmed to be true during the overnight test we started 3 days after the mattress arrived.

At first it may seem very firm, but you will quickly sink to some extent and it will become more comfortable. It is certainly comfortable for all sleep positions, although some side sleepers will find it too stiff. When we talk about breathability, we are very satisfied, you will not be hot when you sleep on this mattress.


And that's all you need to know! So, after reading our Sweetnight Mattress review, do you think this is the mattress for you? Why or why not? Let us know in the comments! And if you have any questions, check out the FAQ section or contact us directly.
