The tendency of Gel-infused foam to be more responsive, meaning switching positions during the night will be more accessible. You’ll have less chance of having a “stuck-in-the-mud” feeling. Apart from this, the presence of wrapped coils makes the Serta Serene Sky mattress responsive.

Comfort, Back Support, Pressure Relief


The foam in Serta serene sky has excellent pressure-relieving qualities, an advantage for those with joint pain issues or for those who primarily side sleepers. Pillow Soft Aire® usually allows the heaviest parts of your body to sink more deeply into the mattress, such as the shoulders and hips. Besides offering extra cushioning, air circulation is good for maintaining temperature neutrality.

Both Base and Comfort Upgrade offer excellent pressure relief. In the case of the Plush Pillow top variety, the pillow-soft HD foam offers pressure relaxation and cradling.

Cooling & Temperature Control


Serta Serene Sky mattresses are known for cooling. Crafted with materials like Cool Twist® Gel Foam enhances the cooling of the mattress. Using comfort layers and support layers with materials that allow air circulation also makes the mattress remain temperature neutral. Besides, the wrapped coils also aid airflow.

Motion Isolation and Sharing a Bed


A coiled mattress engrosses movements like all foam, so the sleeper on one side of the mattress is less likely to be disturbed by motions on the other. This parameter makes Serta Serene Sky mattresses generally a good choice for couples. The foams offer outstanding comfort. The presence of up to 805 individually wound coils, including Serta Best Edge® Foam Encasement technology, enhances the mattress’s support.

Edge Support


The Serta Sere Sky offers excellent edge-to-edge support. Approximately 805 individually wound coils include Serta Best Edge® Foam Encasement technology. People don’t have the sensation of rolling off the border; while sleeping, they enjoy a more excellent surface.

Recommendation based on sleeping style

  • Side Sleepers: more curves are available on our side. Shoulders. Hips. Knees. These areas create tension and pressure. Ideally, a softer mattress cradle the hips and shoulders to prevent stress and injury.
    Firm serene sky mattresses generally deliver more contouring and pressure relief hence ideal for side sleepers. Most people weighing more than 230 pounds finds that a firm variety mattress works well. The other varieties, Plush & Pillow top support side sleepers in the lightweight group. Heavy people will sink deep and may put pressure on the shoulder and hip.
  • Back Sleepers: Sleeping on the back is the best for spine health. Sleepers want a mattress that keeps weight off the joints and pressure points and cradles your spine optimally to maintain healthy alignment.
    Specifically, a firm mattress is great for back sleepers. Firm mattresses prevent the hips and lumbar region from sinking deep and are suitable for the back. Healthy spinal alignment is vital for all types of sleepers.
    Serta Serene Sky comfort upgrade is an ideal one. But the other two varieties with Plush and Pillow top firmness will not keep the spinal alignment healthy and cause aches and pains.
  • Stomach Sleepers-Stomach sleepers are at the most significant risk of spinal problems as there is a great deal of pressure on the thoracic and lumbar spine.
    Ideally- a firm mattress that holds up the hips, reducing pressure on the lower back.
    Only Serta Serta Serene Sky comfort Upgrade 12” can be used as stomach sleepers but only in the lightweight to the average group. Heavy people will exert force, and there will be curvature and cause aches & pains.
  • Combination Sleepers- Sleepers who tend to toss and turn throughout the night change sleeping positions frequently. Depending on their weight, all Serta Serene Sky mattresses can be used.
