Casper Topper – 3 Layer Foam Design

Casper Topper – 3 Layer Foam Design

Casper's mattress topper has an interesting construction and is (super) comfortable.

Last Updated: September 3, 2020

Casper was one of the first companies to pioneer bed-in-a-box mattresses, and have since released several new bedding products that have been pretty popular among online consumers. In this post, we review Casper’s new mattress topper and determine who we think will really enjoy it.

Who Is This Best For?

If you want a “safe” pick (i.e. it’s a comfortable topper)

All sleeping positions

People that like a soft foam feel

Who Won’t Love It?

If your budget doesn’t allow for a $200+ topper

People that are looking to make their bed firmer

Intro: Why Purchase A Mattress Topper?

If you’re in the market for a new mattress topper, it could be for one of several reasons. Maybe you purchased a new mattress and it was a little too firm for you. Instead of spending time and money on buying a new one, you can soften it up with a comfortable mattress topper. Or perhaps you bought a memory foam mattress without knowing if you liked it, and you actually hate it. You can also neutralize the feeling of a bed with a mattress topper.

Maybe you or your child is about to leave the nest, and start their first year as a college freshman in the dorms. A mattress topper is a great way to make those basic bunk bed mattresses feel a little more comfortable.

You may have recently purchased a new Casper mattress and you want to make sure it lasts as long as possible (or any new mattress). Mattresses can be an investment for some people, and toppers help your mattress endure spills, stains, and normal wear-and-tear so you can really get your money’s worth. With that in mind, here is our video review of the Casper Mattress Topper.

There’s a lot more information you’ll want to consider before making a final purchase decision. Keep reading to learn more about the Casper Topper.

Buying And Setting Up Your Casper Topper

Casper knows you’re going out on a limb when you order a product online, and they want you to be sure you love your new topper. So if you decide to give it a try, you’ll receive free shipping, free returns, a 100-night trial, and a 10-year limited warranty. That means you’ll have a little over three months to sleep on the pillow and get used to the way it feels, and the trial starts on the day of delivery. If by the end of the trial you decide you want to return it, get a hold of Casper’s customer service and they’ll kick start the refund process.

If you decide to keep it, you’ll be covered under warranty for an entire decade. Compared to most toppers we’ve tested like the Lucid Topper and Allswell Topper, ten years is pretty dang generous. We always recommend you look at the fine print of their policy, though, just so you know what you’re getting yourself into.

The topper will show up in a seemingly small box for its size, but it’ll be rolled up and compact. Just take it out of its packaging and unroll it over your mattress. You don’t need to let it sit like you do with most bed-in-a-box mattresses, it’s ready to go as soon as you unbox it.

Just as a pro-tip—put aside your receipts in a safe place just in case you want to return it, or if you want to make a warranty claim later down the line.

Price Table For This Topper

You can get a Casper Topper that fits almost any mattress size: twin, twin XL, full, queen, king, and CA king. A twin size topper starts at around $195, and the price for a king/CA king topper goes up to about $355.

Twin XL$215
Cal King$355

We certainly wouldn’t call categorize Casper’s topper as a budget topper, but it’s not the priciest one we’ve ever seen either. To give you some perspective, it’s more expensive than “Amazon’s Choice” topper Linenspa, but less than the TempurPedic Topper. So it may not be great for somebody with a cup-of-noodle budget, but if you’re not price conscious, you might think the price is well worth it.

Casper Topper Materials And Construction

We’ve had several memory foam toppers and one neutral-foam topper come through our doors here at The Slumber Yard, but latex toppers are somewhat rare to see. This topper is also constructed with three layers, another unique trait we don’t see too often.

The first slab of material is made with viscoelastic foam which is essentially just memory foam. The middle layer is composed of latex infused with graphite which is good at absorbing your body heat, allowing you to sleep cooler throughout the night.

Finally, the top layer is made with “alt-latex,” (it’s basically polyurethane foam or neutral foam) and it finishes off the topper with comfortable plush feel. We reached out to Casper’s customer service for further explanation on the foam, but they couldn’t disclose the in-depth details. What they could tell us though, was the foams are hypoallergenic and Certi-PUR certified. That means they were made without mercury, lead, PBDEs, TDCPP or TCEP (flame retardants). They’re also constructed with tiny holes for enhanced airflow, which is another feature that helps prevent overheating.

The cover is made with two different materials. The top is made from 82% Polyester, 16% Rayon, and 2% Lycra, so it’s soft when you run your hand across it. You can learn more about the design and materials on Casper’s website.

The bottom is made with 72% Polyester, and 26% Acrylic Latex which isn’t exactly a comfy surface to sleep on. Instead, it’s designed to adhere to your mattress, that way your topper doesn’t go sliding around when you make your bed or lay on top of it. We also think its weight contributes to how well it stays put on your mattress, because the queen size topper (the one we received) is 30 lbs on its own.

The cover is removable, but that doesn’t mean it’s machine washable. And the last thing you want is to run it through the wash, and find it doesn’t fit back around your topper. We suggest you check the wash instructions on its care tag so you avoid ruining the cover. It recommends that you spot clean with mild detergent, and hand wash with cold water if need be. Do not throw the cover through the dryer or again, you’re at risk of shrinking it. Leave it out to air dry instead.

How Does It Feel?

We think the Casper Mattress Topper feels like a soft foam lover’s dream. It’s plush, light, and overall really nice to lay on. It offers gentle support, without compromising its soft feel. We would compare sleeping on the Casper Topper to sleeping on top of a ton of cotton balls, or a fluffy cloud.

We think all sleeper types would enjoy it, especially side sleepers. It’s really pressure relieving, so it’ll feel nice against the sides of your body. On the flip side, we also think it’s supportive enough for back or stomach sleepers.

In most cases, this topper will probably end up making your mattress softer, unless your bed is already on the far side of the spectrum towards soft. But if you have a medium or firm mattress, this will make your bed feel softer for you.

Due to its open-cell structure, it sleeps a little cooler than toppers constructed with memory foam. With that said, we don’t think it necessarily sleeps cold. This one just helps you from getting too hot in the middle of the night, so we think it sleeps pretty temperature neutral.

Our Final Verdict

If we’re completely honest, we think this is one of our favorite toppers we’ve ever tested next to the Tuft & Needle topper we put on our Best Mattress Topper list. Its construction is pretty uncommon compared to other toppers on the market, and it’s a pleasure to lay on. So if you can look past the price of Casper’s topper, and you’re looking to soften up your mattress, we definitely recommend trying this one out. Worse comes to worst, you can return the topper for a full refund if it turns out you don’t like it as much as we did.
