Full

Dimensions: 53” x 75”
The full mattress is a good starter mattress for young adults or recent grads living on their own for the first time. Sometimes called a double, the full is 16 inches wider than a twin at 53 inches wide and 75 inches long. A full is not recommended for couples who like to share the bed with pets or their children or enjoy sleeping like starfish. However, it is a smart choice for guest rooms or couples who enjoy a solid night of snuggles.

Memory Foam vs. Hybrid Full Size Mattresses

Full size memory foam mattresses are celebrated for their unparalleled body-hugging and motion-absorbing properties, making every sleeper feel embraced. They offer a custom-fit sleep experience, adapting impeccably to your body, alleviating pressure points.

Hybrid mattresses, on the other hand, revolutionize sleep by blending the comfort of memory foam with the sturdy support of springs. This dynamic duo promises a mattress that delivers the softness of memory foam while promoting optimal airflow, stellar edge support, and a touch of buoyancy.

Frequently asked questions

How Casper keeps prices low and quality high

When Casper was founded in 2014, many people were skeptical. Would consumers really buy a standard king size mattress without testing it first? Several years and numerous awards later, we have an answer: It turns out no one likes visiting stuffy mattress showrooms to make high-stakes purchases under the scrutiny of needy salespeople. (Who knew??)

Everyone loves the ease and convenience of buying online from a trusted source, and having a high-quality mattress shipped in a box to their doorstep. And people keep spreading the word that our mattresses deliver unparalleled comfort and support, top-notch construction quality, and high-tech, innovative design.

But the Casper experience isn’t just about quality, trust, and transparency. Our mattresses are a mere fraction of other brands’ prices. That’s because we’ve flipped the mattress industry on its head. By eliminating showrooms and middlemen, we keep our costs low - and pass those savings on directly to you.
