【Safer Materials for Better Sleep】Your safety is always the top priority. That's why the MSjh hybrid mattress is 100% fiberglass-free and certified by CertiPUR-US to meet their standards for content, emissions, and durability. So you can focus on what really matters: getting a good sleep 【Take Off the Pressure】Design combines coils and gel memory foam to promote better spinal alignment, helping relieve pressure points beneath your shoulders, hips, and legs, ensuring you have full-body stable support all night. Perfect for side, back, and combination sleepers 【Move Freely, Sleep Deeply】Successful motion isolation is the key to a restful night- and to a happy relationship. Individually wrapped colls move independently from one another, ensuring that every toss and turn doesn't make it to the other side of the bed. So you can move freely, while your partner sleeps soundly 【Reinforced Edge Coils】Reinforced edge coils ensure the strength and overall integrity of your mattress, so you feel supported lying close to the sides 【Medium Feel Support】 We describe our mattresses as medium feel. Right in the middle of the firmness scale, where you get the sweetest comfort and support. If you are torn between which feel is best for you, we recommend medium feel. With over 80% of sleepers preferring a mattress with a firmness rating between 5.5 and 7.5, the medium feel falls right in that sweet spot
