There, the Casper Original was checked for heat retention by cycling an electric blanket on and off for several hours and measuring how quickly the heat dissipated during the “off” periods. While I had the Casper, I assessed my overall experience, as well as specifics like: whether it felt hot overnight, how well it supported my body in different sleep positions, its ability to isolate motion, if the edges collapsed when I lay or sat on them, if I could easily roll from one position to another on the mattress without feeling bogged down, and its bounciness or lack thereof.īut subjective testing isn’t enough for us, so we also welcome each mattress into our labs in Cambridge for objective trials. The month-long period also ensures it has sufficient time to firm up after being opened (an important step, as these things are compressed to fit into a box that’s less than half their size), and to off-gas any chemical odors, a common process for foam products.

This gave me enough time to ensure it doesn’t cause discomfort in my back, neck, or shoulders. As with all mattresses, I slept on the Casper Original for a month. Here at Reviewed, mattress testing is everything you could dream up, and then some. The Casper went through a battery of assessments including a home sleep test and rigorous lab testing. How did we test the Casper Original mattress? The next layer is composed of memory foam with “zoned support,” which the company claims is “divided into three ergonomic zones that help keep your spine aligned.” (A customer service rep couldn’t clarify exactly how the different zones are created, though, and said that the majority of the cushy or firm sensation comes from the top and bottom layers.) Finally there’s the base layer, which is denser and more durable and aims to provide support and prevent you from sinking through. The Casper Original’s uppermost internal layer is made of perforated foam, which purports to promote airflow and improve your sleep experience by helping you stay cool.

The Casper Original, its baseline mattress, is made with three layers of foam encased within a blended fabric cover that consists of polyester, cotton, rayon, and lycra.

Casper is a prominent mattress-in-a-box company that now sells a variety of other products.Ĭasper is best known for its mattresses, but since its inception has branched out into other areas of bedding-it even makes a dog bed that one of our writers (and her dog) absolutely adore.
