What Is <\/strong>the Saatva Rx Mattress<\/strong> Made Of? <\/strong><\/h2>\n\n\n\n

Let\u2019s take a look at what the Saatva Rx is made of.<\/p>\n\n\n\n

<\/figure>\n\n\n\n

Cover \u2013<\/strong> The Saatva Rx has a quilted organic cotton cover, which adds a plush feel to the surface of the mattress. The cover is treated with Guardin botanical antimicrobial treatment. Additionally, the cover has a fire barrier made with plant-based thistle pulp \u2014 no fiberglass or chemical flame retardants.<\/p>\n\n\n\n

Zoned Support Layer \u2013 <\/strong>In the middle section of the mattress is a \u00bd-inch gel-infused memory foam strip, which provides extra support and pressure relief around the lumbar region.<\/p>\n\n\n\n

Comfort Layer<\/strong> \u2013<\/strong> The Saatva Rx has an unusual comfort layer, consisting of a 1-inch microcoil layer encased by 2 \u00be-inch high-density foam layers above and below. This combination of foam and microcoils creates a comfortable, but highly supportive feel right off the bat.<\/p>\n\n\n\n

Support Layer \u2013<\/strong> The Saatva Rx also has a unique support layer. It features an 8-inch section of pocketed coils made from recycled steel, with firmer caliper spring coils around the edges for reinforced edge support. <\/p>\n\n\n\n

On top of each coil is a 2-inch Rx Foam Module. These look like small, cylindrical foam caps. The foam is infused with cooling graphite and phase change material to provide a cooler sleep experience. These foam caps are intended to improve motion isolation and provide additional body contouring.<\/p>\n\n\n\n

Base Layer \u2013 <\/strong>Underneath the coils is a layer of what Saatva calls an \u201ceco non-woven base layer,\u201d which provides a sturdy surface for the coils to rest on.<\/p>\n\n\n\n

Saatva Rx Mattress<\/strong> Firmness <\/strong><\/h2>\n\n\n\n

Now let\u2019s talk about the firmness and feel of this bed. At Sleepopolis, we rate firmness on a scale from 1 to 10, where 1 is the softest and 10 is the firmest. We use 6.5 as the standard for medium-firm, the most common mattress firmness. To determine the firmness of each mattress, we test laying on it in different positions and compare it to the hundreds of other mattresses we\u2019ve tested. Then we rank it on the scale.<\/p>\n\n\n\n

<\/figure>\n\n\n\n

After testing it out, I rated the Saatva Rx as 6.5 out of 10 on the firmness scale<\/strong>, as I thought it had a true medium-firm feel. The mattress offers a pleasant mix of comfort and support to create that balanced, medium-firm feel. While lying on the bed, I experienced plushness and cushioning from the quilted cover and upper foam layers, but felt firmly supported by the coils below. I think the unique design of this bed, with features like microcoils and the foam caps on the pocketed coils, contributes to this very balanced feel.<\/p>\n\n\n\n

Sleeping Position<\/strong> and Body Weight<\/strong><\/h2>\n\n\n\n

Now let\u2019s talk about how sleepers of different weights will feel in each sleeping position on this mattress.<\/p>\n\n\n\n\n\n

Here\u2019s my take on how different sleepers will experience the Saatva Rx.<\/p>\n\n\n\n

Is <\/strong>the Saatva Rx<\/strong> a Good Mattress for Light Sleepers (Under 130 pounds)?<\/strong><\/h3>\n\n\n\n

\n

\n

• Light <\/strong>Back Sleepers<\/strong> \u2013<\/strong>  I think light back sleepers should be happy on the Saatva Rx, although it may feel a touch firmer to these folks than it did to me. Still, the Saatva Rx\u2019s highly balanced feel means light back sleepers will find their spines easily aligned, while still receiving some plush comfort.<\/li>
• Light <\/strong>Side Sleepers<\/strong> \u2013<\/strong> The Saatva Rx may be a bit too firm for light side sleepers, who won\u2019t sink very deeply into the material. It could work for occasional side sleeping, but for light sleepers who strictly rest on their side, I\u2019d recommend something a little softer.<\/li>
• Light <\/strong>Stomach Sleepers<\/strong> \u2013<\/strong> Light stomach sleepers should be very comfortable on the Saatva Rx. I think it is firm and supportive enough to keep these sleepers\u2019 hips lifted up for proper spinal alignment.<\/li><\/ul>\n<\/div>\n\n\n\n

  Is <\/strong>the Saatva Rx<\/strong> a Good Mattress for Average Weight Sleepers (130\u2013250 pounds)?<\/strong><\/h3>\n\n\n\n

  • Average Weight Back Sleepers \u2013<\/strong> The Saatva Rx is an excellent match for average weight back sleepers. As someone who falls into this category, I felt extremely comfortable on the Saatva Rx. This bed is highly supportive, so I felt my spine was neutrally aligned and supported. But the bed still offers plushness and comfort.<\/li>
  • Average Weight Side Sleepers \u2013 <\/strong>I think the Saatva Rx is a good match for average weight side sleepers. I felt my shoulder and hip were both well-cushioned while resting on my side on the Saatva Rx.<\/li>
  • Average Weight Stomach Sleepers \u2013<\/strong> I didn\u2019t expect the Saatva Rx to work well for stomach sleeping, since I had felt so much cushioning in the other two positions, but I was surprised to find my hips weren\u2019t sinking into the material. I think the microcoils likely played a role here in providing that extra lift. All that being said, this bed is a good match for average weight stomach sleepers.<\/li><\/ul>\n\n\n\n

    Is <\/strong>the Saatva Rx<\/strong> a Good Mattress for Heavy Sleepers (over 250 pounds)?<\/strong><\/h3>\n\n\n\n

    \n

    \n

    • Heavy <\/strong>Back Sleepers<\/strong> \u2013<\/strong> I think heavy back sleepers should be extremely comfortable on the Saatva Rx. As I mentioned before, this bed is super supportive, so heavy folks shouldn\u2019t have to worry about being adequately supported. This bed provides a nice lift, but still offers comfy cushioning.<\/li>
    • Heavy <\/strong>Side Sleepers<\/strong> \u2013 Heavy side sleepers should be quite cozy on the Saatva Rx, too. I think it can be hard to find a sturdy bed that also provides enough cradling and contouring for heavy side sleepers, but I think the Saatva Rx should be a good match.<\/li>
    • Heavy <\/strong>Stomach Sleepers<\/strong> \u2013 The Saatva Rx may work for some heavy stomach sleepers, but I would caution that they might find their hips sinking into the material more than I did. A slightly firmer bed might work better for some heavy stomach sleepers.<\/li><\/ul>\n<\/div>\n\n\n\n

      Saatva Rx Mattress<\/strong> Performance<\/strong><\/h2>\n\n\n\n

      In addition to assessing the materials, firmness, and feel of each mattress, we also like to put mattresses through a series of tests on performance factors like pain relief, motion isolation, cooling, and more. Below, I\u2019ll detail the results of my tests on the Saatva Rx.<\/p>\n\n\n\n

      Saatva Rx Mattress<\/strong> Pain Relief Performance<\/strong><\/h3>\n\n\n\n

      \n

      \n

      Pain relief is one of the Saatva Rx\u2019s biggest promises, so this test was of special interest to me. To test how well a bed relieves pressure and pain, we use a heat-mapping pressure map. This device is a mat we lay on top of the mattress that uses thermal imaging to measure pressure buildup. We then lay on the mat in different sleeping positions and it generates a color-coded image to show the pressure points.<\/p>\n\n\n\n

      As you can see, the Saatva Rx did a good job relieving pressure for me in both the back and side sleeping positions. There is very little pressure buildup showing on these pressure maps, indicating this bed should be effective at pressure relief for back and side sleepers.<\/p>\n<\/div>\n\n\n\n

      Motion Transfer<\/strong><\/h3>\n\n\n\n

      Motion transfer is an important test for those who share the bed with a partner or pet. If you\u2019ve ever felt like you were bobbing up and down every time your partner tossed and turned, then you\u2019ve experienced motion transfer. Ideally, a bed should be able to isolate motion at the source and prevent it from transferring across the bed.<\/p>\n\n\n\n

      We come up with our motion transfer score using a few different tests. The first one is simple: we just lie down on the mattress with a colleague, roll around, and see how much of each other\u2019s movement we feel. We also place a full wine glass on the mattress and see how much the wine moves around with us. If the liquid has zero to little movement, then it\u2019s a safe bet that the mattress has low motion transfer, which is what you want to see.<\/p>\n\n\n\n

      <\/figure>\n\n\n\n

      Finally, there\u2019s our seismometer test. This involves dropping a 10-pound steel ball from heights of four inches, eight inches, and 12 inches, then measuring the disturbance it causes: the bigger the lines on the graph, the bigger the disturbance and the higher the motion transfer.<\/p>\n\n\n\n

      These are pretty good results, showing that the Saatva Rx isolates most motion and prevents it from transferring across the bed. You might feel some larger movements on this bed, but overall I think it will prevent most motion from causing disturbances among couples (or those who sleep with a pet).<\/p>\n\n\n\n

      Responsiveness<\/strong><\/h3>\n\n\n\n

      We also like to test responsiveness, or how quickly a bed responds to pressure. This corresponds to how easy it is to move around on the mattress. We test responsiveness by moving around on the mattress and seeing how easy or difficult it is.<\/p>\n\n\n\n

      I found the Saatva Rx pretty easy to move around on. While the bed doesn\u2019t offer a ton of sinkage to the point of making it difficult to change sleeping positions, I also didn\u2019t find the bed to be overly bouncy. It took a little effort to move around, but nothing too extreme. Overall, I would say the Saatva Rx is fairly responsive.<\/p>\n\n\n\n

      Cooling<\/strong><\/h3>\n\n\n\n

      Cooling is an important factor for many people, whether they live somewhere warm or simply run hot at night. We look at two things to determine how cooling a mattress is: its construction and how it performs in our thermal gun test. <\/p>\n\n\n\n

      Looking at the Saatva Rx\u2019s construction, I felt it should be a decently cooling mattress. Being a hybrid with a large section of coils, the Saatva Rx should be breathable and have room for hot air to escape. The bed also has a cotton cover, which is another breathable material. But there is still a decent amount of foam, which could cause some heat trapping.<\/p>\n\n\n\n

      We also test out each mattress with a device called a thermal gun, which uses color-coded imaging to measure how much and how quickly a mattress heats up when we lie down on it. If it heats up more than 15 degrees Fahrenheit, we consider it to have poor cooling capabilities. 10 to 15 degrees indicates decent cooling, 5 to 10 degrees indicates good cooling, and less than 5 degrees indicates excellent cooling.<\/p>\n\n\n\n
