Zinus vs Casper: Which One is Better for You?Casper and Zinus mattresses are great and offer a superior level of comfort. But since they are not 100% the same, it may be difficult for you to narrow down the one that will suit you best. To help you make an informed decision, we considered some features that determine how comfortable and sturdy a mattress will be.

Support and firmness level

Support is what keeps a mattress from collapsing when weight lies or sit on it, so it makes sense to pay close attention to the level of support a mattress offers before making a purchase. Zinus and Casper mattresses are well crafted and have multiple support layers that are durable and sturdy.

Before choosing a mattress, it is important that you check how firm it is; especially if you are a heavy person or you sleep on your stomach.

Firmness is usually represented in three terms- soft, medium, and firm.

  • A firm mattress is perfect for heavy people (200lbs and above).
  • A Medium-firm mattress is a good fit for a person who weighs between 150 to 200lbs.
  • Go for the plush or soft mattress if you are a side sleeper and you weigh 150lbs and below.

The different Zinus mattress models offer a different level of firmness. But we believe that the 10-inch model will be suitable for most people, as its top and second layer is designed to support the whole body and promote spinal alignment. Casper mattresses, on the other hand, is a good pick for all sleeping positions. Its special zoned support layers help to distribute your body weight evenly on the bed, thus promoting a neutral spine. The bottom line is that both Casper and Zinus offer just about the same level of firmness.

Temperature control

Zinus mattresses have a special foam base that helps prevent heat buildup and promote airflow. Also, their cover is breathable, allowing enough air to reach you while your sleep. On the other hand, Casper mattresses have a handful of cooling features, including a unique open-cell structure on the top of the foam that allows air to move freely. Since they don’t create much sinkage, you won’t have to worry about them retaining heat.

Motion transfer

Zinus vs Casper: Which One is Better for You?Motion Transfer refers to how well a mattress absorbs vibration and stops it from traveling across the bed. This is a crucial feature especially for couples, since a bed with poor motion isolation will easily disturb their sleep or even worse, cause a partner to wake up when the other moves when sleeping.

Zinus mattress has a comfortable memory foam feel and is great for motion isolation as the viscoelastic nature of the mattress enables it to absorb vibrations easily. Also, it creates a comfortable cradling hug when you lie down on it. This means that you will slowly sink into the bed when you lie on it. This will go a long way in providing relief for your back pain.

Casper mattress is a great option for couples, as it has a thick and dense foam foundation that help absorb motion and isolate vibrations in the mattress.


The responsiveness of a mattress is another important feature you must give attention, regardless of the model you are opting for. A good mattress should be responsive and have minimal motion transfer, as this will go a long way in ensuring that the mattress contours well with your body and gives you the comfort and bounce you need.

Comparing Casper and Zinus, you will observe that both of them are soft, comfortable, and responsive. But Zinus is slightly more responsive than Casper. These two are so closely matched on this that you may not notice the difference between them.

Resilience and bounce

Since you are going to be spending a sizable chunk of your time in bed sleeping or resting, it is wise that you check how a resilient a mattress is before making a purchase.

Zinus and Casper mattresses are firm, sturdy, and comfortable. Since they both have multiple layers of premium quality, dense, and comfortable foam, you can be sure that it won’t become saggy or sink after a while. However, if you are a heavy person, it is wise you opt for models of any of the two brands that are very firm.

Edge support

Zinus vs Casper: Which One is Better for You?As you likely know, the edge support of a mattress is determined by the size of its base layer. And both Casper and Zinus mattresses offer just about the same level of edge support. While Zinus comes with a 5.5-inch dense base layer, Casper has a 5 inches’ thick base layer. The bottom line is that both of them are sturdy and offers almost the same level of edge support.

Inflation time, off-gassing and smell

A new memory foam mattress usually emanates a certain chemical smell. The obvious reason for this is that memory foams are fully compressed before shipping. So, when you open them for the first time, the chemical odor will spread out quickly. The best way to address this is to open your windows and leave the mattress for 2 to 3 days. This will make the mattress expand to its full size and the chemical smell will disappear.
