Sweetnight Dreamy S1 Performance Highlights

Pros

  • Spine Alignment: Sweetnight uses a gel-infused memory foam to keep your spine in a neutral position at night.
  • Responsiveness: This mattress does a great job of allowing you to change positions, especially on the firmer side.
  • Edge Support: When sitting on the edge of the Sweetnight Dreamy S1, you may feel like you’re sitting on a chair since it has such great edge support.

Cons

  • Durability: Since this is an all-foam mattress, it likely won’t last as long as some other mattresses and may start to tear after some use on it, but because it comes at a low price it won’t be expensive to replace in a few years.
  • Set-Up: Setting up the Sweetnight Dreamy S1 took a little longer than other mattresses we have tested and we noticed it took a decent amount of time to fully expand.

Edge Support

Here at Mattress Advisor, we test every inch of the mattress and this includes the edges. If you’re the type of person who likes to take full advantage of your sleep real estate, then you understand how important it is to have a bed that fully supports you. When sitting on the end of the Sweetnight Dreamy S1, we felt like we were sitting in a chair, leading us to give it a 9/10 in this category.

Pressure Relief

In our mattress lab, we use a pressure relief map to see how well a mattress does at relieving pressure when you sleep. The map uses warmer colors, like yellow and red, to show areas of pressure buildup and cooler colors, like blue and green, to show where it doesn’t.

On the firm side of the mattress, it was all blue when our lighter and heavier testers lay on their backs. The map showed some pressure buildup in the hip area when the testers lay on their sides and our lighter tester also had some pressure buildup in her shoulder area.

When we tested the pressure relief on the softer side, the mattress did a good job of relieving pressure for the testers lying on their backs. We again noticed some pressure buildup in the hip area for the lighter tester when they lay on their side but the heavier tester had no pressure buildup. If you’re a lighter side sleeper, you may want to consider a mattress like the Saatva Classic, which provides a better pressure relief.

Spine Alignment

Another area we test when looking at mattresses is spinal alignment, since it’s important to maintain a neutral position at night. Our tester’s back was mostly straight when lying on their side, leading us to give it a near-perfect score. The gel-infused memory foam helps keep the back aligned properly.

Product Details

Where Does It Fall on the Firmness Scale?

Since this is a dual-sided mattress, the Sweetnight Dreamy S1 has two different firmness options. The softer side is about a 5/10 on the firmness scale. The gel-infused memory foam makes it doughy and gives the feeling of sleeping in the mattress, rather than on.

We rated the other side a 6.5 since it was similar to a medium-firm mattress. In contrast to the other side, it was very elevating and made us feel like we weren’t sinking.

Does the Sweetnight Dreamy S1 Sleep Cool?

Staying cool while you sleep is just as important, if not more, as when you’re awake. The Sweetnight Dreamy S1 is a cool-to-the-touch mattress that uses gel-infused memory foam to help regulate your body temperature. However, since it’s a memory foam mattress, we felt it wasn’t as breathable as some other mattresses that use coils or latex. For the average sleeper, this should keep them cool enough, but if you tend to sleep hot, take a look at our top cooling mattresses.

What Sleeping Positions Does It Work For?

Most body types should find that this mattress works for all positions. Since this has two firmness options, it’s a great option for stomach and back sleepers who like a firmer support while still being soft enough for side sleepers. However, if you are a lighter side sleeper or someone with sensitive shoulders, you may want to take a look at our best mattresses for side sleepers since this mattress can cause pressure buildup.

How Much Weight Does the Sweetnight Dreamy S1 Mattress Support?

The Sweetnight Dreamy S1 mattress can support up to 551 lbs. If you or your partner weighs more, you might want to consider getting the mattress in a thicker model to ensure long-lasting durability. The one we tested was a queen-size 10” model, which we felt did a good job holding both of our testers.

What Foundations or Bed Frames Are Compatible?

According to the Sweetnight website, their mattresses can be used with all types of bed frames. This includes those with box springs. When using slatted frames, make sure the slats are no more than 3” apart to ensure proper support.

Sweetnight Dreamy S1 Mattress Materials

As an all-foam mattress, the Sweetnight Dreamy S1 uses several layers of CertiPUR-US certified foam.

  1. Mattress Cover: The Sweetnight Dreamy S1 is wrapped in a skin-friendly cover, thoughtfully decorated with a swirly design.
  2. Pressure Relieving Memory Foam: Its first layer consists of a pressure-relieving memory foam, ideal for those who prefer softer mattresses.
  3. Gel-Infused Memory Foam: A breathable gel layer transfers heat away from your body at night so you can sleep at the perfect temperature.
  4. High-Density Support Foam: This layer provides a firmer option for those who prefer mattresses that give a little more support.
  5. Breathable Bottom Knitted Fabric: The Sweetnight Dreamy S1 has a bottom-knitted fabric that promotes breathability.

What’s Unboxing Like?

The Sweetnight Dreamy S1 comes wrapped in plastic and compressed in a square cardboard box. When unboxing the mattress, we noticed the box was glued shut, which made it a little harder to open. Unlike some other compressed mattresses that you can start unrolling, we had to cut the plastic off first. In total, it took us just over 2 minutes for our two testers to unbox the Dreamy S1.

Once fully unwrapped, the mattress will slowly start to expand. We noticed it took quite a bit of time for the mattress to puff up fully, especially in the corners. Sweetnight advises giving the mattress 72 hours to take its full shape before sleeping on it.
