What mattress is right for you?
Your mattress preference depends on several factors. A risk-free trial is imperative since you won't know if a mattress is right for you until you sleep on it for two to four weeks. Fortunately, most mattresses we recommend have trial periods of 100 nights or more.
Your sleep position usually determines the best mattress firmness for you. Softer mattresses, like the Casper Nova Hybrid, are best for side sleepers since they allow the hips and shoulders to sink in, keeping the spine aligned, which is crucial for a good night's sleep. Stomach sleepers gravitate to firmer mattresses, like the Awara Hybrid, because they don't want to sink in as much, while back sleepers are in the middle. Body size also plays a role. Firmer mattresses tend to be more supportive for heavier individuals. Softer mattresses allow petite people to sink in more.
What are the different mattress types?
Hybrid mattresses are popular because they combine individually wrapped coils and memory foam to provide supportive comfort. They're usually durable and promote airflow for a cooler sleep. The Casper Nova Hybrid is a top pick in our best hybrid mattress guide. It's currently $450 off. Read our full Casper Nova Hybrid Mattress review.
Memory foam mattresses are more affordable and mold to the contours of your body. Foam often traps heat, which is great for cold sleepers but awful for hot sleepers. Check out our guide to the best foam mattress for our top picks.
Latex foam is pricier but breathes better and has a more responsive feel. The Birch Natural is our pick for the best latex mattress. It's marked down 25% for Prime Day.
Popularized by Sleep Number, adjustable air beds use air to customize your mattress's firmness for optimal comfort. This is a great option for couples with drastically different comfort preferences. Our favorite, the Sleep Number 360 i8, is currently marked down $1,200. Read our full Sleep Number 360 i8 Smart Bed Review.
