If you’re stuck choosing between the Casper Original and the Zinus Green Tea Memory Foam Mattress, you’re not alone. Both are popular all-foam mattresses, but they have very different features and price points. Casper uses advanced foam technology for support and cooling, while Zinus offers an affordable and fresh-smelling sleep option. But which one is better for you?

In this blog post, we’ll break everything down—firmness, feel, support, motion transfer, cooling, and more—in a way that’s super easy to understand. Let’s find your perfect mattress match.

Casper “The One” Mattress – What You Need to Know

Casper’s “The One” mattress is designed to offer a mix of comfort, support, and cooling. It’s made with special foam layers that adjust to your body and help keep your spine in a natural position while you sleep. One of its key features is the Zoned Support™, which means the mattress is softer under your shoulders and firmer under your hips and waist. This helps keep your back straight, which can reduce pain over time.

Another great thing about this mattress is its AirScape™ foam, which has tiny holes to allow air to flow through the mattress. This helps prevent heat from building up, so you stay cooler during the night. Casper is a good option for many people—especially couples, hot sleepers, and anyone with back issues. It’s more expensive than Zinus, but you’re paying for upgraded features and better support.

Who Should Get the Casper Mattress

Here are the types of people who might really enjoy the Casper mattress:

• Couples – If you share a bed and don’t want to feel every little movement your partner makes, Casper is great at blocking motion. You can toss and turn without waking the other person.

• People with back pain – The Zoned Support™ gives just the right amount of firmness and softness in the right spots, helping to keep your spine straight.

• Hot sleepers – The AirScape™ foam helps cool you down, so if you often get sweaty during the night, this feature can help you sleep better.

Zinus Green Tea Memory Foam Mattress – What You Need to Know

The Zinus Green Tea mattress is well-known for being affordable while still offering comfort and pressure relief. The mattress has three main foam layers and uses green tea extract and castor seed oil in the top layer. These natural ingredients give the mattress a fresh, clean smell that’s different from many other foam beds, which can sometimes smell like chemicals at first.

It’s a great mattress for people who like a softer, “hugging” feeling when they lie down. Zinus is also CertiPUR-US® certified, which means it’s made without bad chemicals or heavy metals. While it may not have the same advanced features as Casper, it does a good job for the price—especially for side sleepers and people who move around a lot in their sleep.

Who Should Get the Zinus Mattress

Zinus might be the right fit for you if:

• You’re on a budget – It’s one of the most affordable memory foam mattresses on the market and still gives you solid comfort.

• You want a mattress that smells fresh – The green tea scent is calming and helps avoid that “new mattress” smell.

• You sleep in different positions – Zinus works well for side, back, or combo sleepers and comes in a few height options.

Casper vs. Zinus: What They Have in Common

Although these mattresses are very different in price and design, they still share a few things:

• Pressure Relief – Both have foam layers designed to take pressure off your hips and shoulders, which can help reduce body pain.

• Medium-Firm Feel – They both rate at a 6/10 on the firmness scale, which is a good middle ground for most sleepers.

• Bed-in-a-Box – Both come compressed in a box and are delivered straight to your door, which makes them easy to set up.

Casper vs. Zinus: Key Differences

Here’s what sets them apart:

• Price – Zinus is much cheaper than Casper, making it more budget-friendly.

• Cooling – Casper does a better job at keeping you cool, thanks to its perforated foam layer.

• Smell – Casper might have a stronger “new bed” smell at first. Zinus smells fresher because of the green tea and natural oils.

• Edge Support – Casper offers better edge support, so you don’t feel like you’ll roll off if you sit or lie near the sides.

How They Feel: Firmness, Support & Comfort

Both mattresses are medium-firm, which means they aren’t too soft or too hard. This firmness level works well for most people. Here’s how they compare:

• Casper: Feels soft at first, then gives more support as you sink in. It’s good for spinal alignment.

• Zinus: Offers a soft, body-hugging feel. It’s cozy but may not support heavier body weights as well as Casper does.

Sinkage and Bounce

Because both are foam beds, they don’t have a lot of bounce. You’ll sink in gently, which many people find comfortable for sleeping. However, if you need a bed that’s easier to move on or better for sex, you might prefer a hybrid mattress with springs.

• Casper: Slight sink, with a firmer feel underneath. You don’t feel like you’re stuck in the mattress.

• Zinus: More classic memory foam feel—slower sink and more contouring around the body.

Motion Isolation – Great for Couples

Both mattresses are great at absorbing motion. This means that if your partner moves around or gets out of bed during the night, you’re less likely to feel it. This is one area where both Casper and Zinus do very well.

Cooling – Which Sleeps Cooler?

Casper clearly has the edge when it comes to staying cool at night. Its AirScape™ foam helps air move through the mattress, which prevents overheating. Zinus does okay, but you might get warmer on it—especially if you’re a hot sleeper. Zinus also offers gel-infused models that help with cooling, but they cost a bit more.

Mattress Construction – What’s Inside?

Zinus Construction

• Top Layer: Green tea memory foam with natural oils to fight odors and keep things fresh.

• Middle Layer: 2-inch foam that adds comfort and helps with pressure relief.

• Base Layer: 5.5-inch high-density foam with an egg-crate design that supports your body and promotes airflow.

Casper Construction

• Top Layer: AirScape™ foam that’s soft, breathable, and slightly bouncy.

• Middle Layer: Zoned Support™ with different firmness zones for shoulders, hips, and waist.

• Base Layer: Durable support foam that keeps the bed stable and long-lasting.

Both mattresses are made from CertiPUR-US® certified foam, meaning they’re safe and free from harmful chemicals.

Company Policies – What You Get

• Warranty: Both Casper and Zinus come with a 10-year limited warranty.

• Shipping: Both offer free shipping across the U.S.

• Trial Period: You get 100 nights to try either mattress.

• Returns: Zinus allows easy returns within the trial window. Casper also allows returns, but they ask you to sleep on it for 30 nights first.

Price Comparison

• Zinus is the better choice if you’re watching your wallet. It can cost up to $700 less than Casper.

• Casper costs more but offers advanced features like Zoned Support™ and better cooling.

Think of it like this: Zinus gives you the basics at a great price. Casper gives you upgrades for more comfort and support—if you’re willing to pay more.

Final Thoughts – Which Mattress Should You Choose?

If you’re looking for a budget-friendly, comfy mattress that smells fresh and works for all sleep positions, the Zinus Green Tea Memory Foam Mattress is a solid choice.

But if you’re okay with spending more to get better support, cooling, and edge strength, then Casper’s The One is the smarter investment.

In the end, the right mattress depends on your needs, your sleep style, and your budget.
