Frequently Asked Questions

What makes the Realcozy mattress different?

The Realcozy mattress offers responsive comfort and support at a great price. It's built in the USA using American-made foams and certified by CertiPUR-US and USDA.

We offer a 100-night trial and our lifetime warranty. Plus every Realcozy mattress is delivered fast and free to your front door. If you don't love your new mattress, we'll refund your purchase and schedule to get the mattress picked up, either by charity or recycled.

How does the 100-night trial work?

When you purchase a mattress from us, you get to try it out in your home for up to 100 nights. If you don't love it, we we'll refund your purchase. We'll also work with you to get it picked up to be donated or recycled. Our goal is to ensure that you have a stress-free shopping experience and feel confident in your online purchase.

Where is the Realcozy Mattress made?

Every one of our mattresses is proudly made in Tolleson, Arizona. We are a self-sustained company that handles every step of the process in-house. From the initial design stages, through the manufacturing process, and all the way to shipping, everything is conducted under our watchful eye. This ensures that we can maintain the highest level of quality control and deliver a mattress that meets our exacting standards, directly from our factory to your home.

How does this mattress feel?

We describe the feel as medium-firm. It's got some feeling of memory foam, without the "sinking feeling" and supportive and breathable pocketed coils. It's the perfect balance needed for side or back sleepers.

What is a hybrid mattress?

A hybrid mattress is a unique blend of two popular mattress types. It incorporates layers of soft foam and sturdy spring coils in its design. This combination provides the lively bounce and superior airflow you'd find in a classic spring mattress, while also offering the key benefits of traditional memory foam. These benefits include pressure point relief, improved spinal alignment, and minimal motion transfer. In essence, a hybrid mattress brings together the best features of spring and memory foam mattresses for a balanced and comfortable sleep experience.

Is the Realcozy mattress CertiPUR-US®  certified?

Yes, our foams in our mattress are certified by CertiPUR-US®.

CertiPUR-US® certification is a mark of safety and quality awarded by independent accredited testing laboratories. This certification guarantees that the materials used are low in volatile organic compounds (VOCs) and are made without harmful substances such as ozone depleters, phthalates, PBDEs, formaldehyde, and heavy metals. This means you can rest easy knowing your product is both safe and environmentally friendly.

What does the USDA Certified Biobased Product seal mean?

USDA Certified Bioproducts refer to products that have undergone rigorous evaluation and met the stringent standards set forth by the United States Department of Agriculture (USDA) in terms of their environmental sustainability, renewable resource content, and biobased content. These certified bioproducts encompass a diverse range of items derived from renewable resources, such as biofuels, bioplastics, and bio-based chemicals, all of which contribute to reducing reliance on fossil fuels and promoting a more sustainable and circular economy. The USDA certification ensures consumers that the bioproducts they purchase have undergone thorough testing and meet the established criteria for environmental responsibility and resource conservation.

What type of foundation do I need?

You can use any type of solid foundation, platform, metal grid frame, or adjustable base. We do not recommend using box springs, but a box foundation is also okay. Some box foundations look like metal grid frames with slats 4" apart -- these are also perfectly fine.
