Deciding Between Puffy & Casper


Your mattress’s firmness is rated on a scale of 1 to 10, with 1 being the softest and 10 being the 10 most firm. If you are a side sleeper, you want a lower rated mattress that will support your shoulders and hips, and if you’re a stomach or back sleeper, you want a mattress that will support your neck, back, hips, shoulders, and legs.

Both the Casper and the Puffy rate at a 6/10 on the firmness scale, allowing them to accommodate back, side, and combination sleepers, but the Puffy’s firmer foam construction is also great for stomach sleepers who need extra support.

Motion Isolation

When you get in and out of bed, or when you change sleep positions, motion can travel across the mattress. If you share the bed with someone, your movements can disturb them. That is why you want to invest in a mattress that has a high level of motion isolation to prevent that motion from traveling. The Puffy Mattress surpasses the Casper Original Mattress in terms of motion isolation.

Edge Support

Getting in and out of a bed without proper edge support can be difficult, especially as the bed begins to age. It also limits the amount of the mattress you can sleep on. You want a mattress with solid support around its edges so it remains supportive for a long time. The Puffy Mattress delivers better edge support than the Casper because of its support layer.

Pressure Relief 

If you’re waking up sore and in pain, your mattress might be the culprit. Most mattresses are designed to relieve pressure and cradle pressure points so as to maximize your sleep experience; however, this depends on your sleep position as well as the mattress’s construction.

Both mattresses deliver adequate pressure support for sleepers who are light and medium-weight, but the Casper Original Mattress is recognized for providing extra pressure relief for your hips and back, thanks to its Zoned Support layer. The Casper is a good side sleeper mattress because the Zoned Support is soft under the shoulders and hips yet firmer under the back.

Spine Alignment 

The average person spends approximately 8 hours a day in bed. For those 8 hours, you need a mattress that will keep your spine properly aligned, or else you can develop chronic back problems down the road. Both mattresses are known for promoting healthy spinal alignment for side and back sleepers, but for stomach sleepers, you’ll want to lean toward the Puffy because of its extra support. 


A mattress is designed to last a long time, but that doesn’t mean that it’ll keep its shape or structure forever. You want to buy a mattress that is built with a solid foundation or base layer so it has a long lifespan. The Puffy Mattress and the Casper are both guaranteed to last a long time without losing their shape or structure, but the Puffy Mattress has a lifetime warranty to protect your purchase.


Many people find that traditional memory foam mattresses trap heat. Newer mattresses incorporate innovative heat reduction and cooling technology into their construction. The Puffy Mattress and the Casper Original Mattress do fine for warm sleepers, but the Puffy Mattress is particularly targeted for people who get hot at night and therefore the better cooling mattress.

Casper vs. Puffy Mattress Construction 

Casper Construction

Casper Original Mattress
Cover Polyester blend
Comfort Layer Open-cell memory foam
Transitional Layer Transition foam/Zoned Support layer
Support Layer Support foam
Mattress Thickness 11 inches

The Casper Original Mattress starts with a top layer made of open-cell memory foam, which encourages airflow and delivers soft bounciness that keeps you cool and cradles your pressure points.

The next layer is responsive and contouring memory foam that accommodates your body’s unique shape. Following that is the transition foam layer, also known as the Zoned Support layer. This layer is firmer under your back and hips, but softer around your shoulders, so that you get the right level of support where it’s most needed. The Zoned Support layer makes the Casper a great mattress for back sleepers who need firmer support under their lower back with cushioning beneath their shoulders and hips.

Finally, the mattress base layer is made of support foam that allows the mattress to retain its shape and structure.

Puffy Construction

Cover Stain-resistant cover
Comfort Layer Cooling Cloud, gel-infused foam
Transitional Layer Climate-Adaptive Foam
Support Layer Firm Core Support Layer
Mattress Thickness 10 inches

The Puffy Mattress’s top layer consists of breathable Cooling Cloud memory foam that wicks heat away from your body and keeps you cool at night, while also reducing pressure on your body.

The second layer features unique technology called Climate-Adaptive Foam, which further reduces heat and humidity while you sleep. The base layer is known as the Firm Core Support Foam Layer and helps your Puffy Mattress retain its shape and structure for years to come.

Shipping and Returns for Puffy & Casper

Puffy Mattress

The Puffy Mattress ships anywhere in the contiguous United States for free, but there will be shipping charges for Hawaii and Alaska residents. You can expect your mattress to arrive at your front door compressed and rolled up in a box. Setup is as simple as opening up the box, placing the mattress on your bed frame, unrolling the mattress, unrolling the mattress, and then allowing it to regain its shape, which can take several hours.

Puffy allows you to test out your mattress for 101 nights, risk-free and offers Lifetime warranty coverage. If you find yourself unhappy with the mattress during that sleep trial period, you can request a return, which is free of charge as long as it’s within the 101 nights. It’s best to give your mattress approximately 30 days to break in and to allow your body to become used to it.

If you’re sure you want to return it, simply call the customer support line with your order number and request a return. Your returned mattress will be donated to a local charity or brought to a recycling center, and you’ll be refunded in a few business days.

Casper Mattress

Residents of the continental United States can have their Casper Original Mattress shipped to them at no cost. If you live in Alaska, Hawaii, or certain Canadian provinces, you may incur a shipping charge. Your mattress will be delivered to your door via UPS, and you will be provided with a confirmation number once it’s shipped so that you can track your package the entire time.

Casper provides in-home setup to US residents for an extra charge. When you select this option, the delivery team will reach out to you with a four-hour delivery window of when they will arrive. They will bring your new mattress inside, set it up on your bed frame, then remove and dispose of your old mattress and packaging materials. Please note that this service does not include disposal of old bed frames.

Your new mattress from Casper comes with a 100-night trial period and a 10-year limited warranty. If you’re unhappy with your mattress for any reason during the 100-night trial, you can return it hassle and charge-free. It’s recommended that you wait approximately 30 days from your delivery date before initiating a return as it can take a month for your new mattress to break in.

To learn more about both warranties, see our Casper Mattress Warranty & Puffy Mattress Warranty for details on what each warranty covers.

Our Final Take

Both the Casper and Puffy mattresses are all-foam, made to suit most sleep positions, and offer advanced cooling.

However, if you’re a stomach sleeper who wants extra support, we recommend the Puffy Mattress instead.
