What to Consider When Finding the Best Mattress in a Box

Choosing the best mattress in a box to ensure sound sleep quality is essential, as this can promote healthy sleep stages. But it depends on a few key factors like:

Your Sleeping Position and Body Weight

Matching mattress firmness to body types and preferred sleeping positions is crucial for optimal comfort. A softer mattress is ideal for small to medium-sized side sleepers. However, for back or stomach sleep positions or for those who are heavier, the best firm mattress in a box is recommended.

Mattress Type

Not all mattresses are suitable for all sleepers. Side sleepers generally do better with foam and even hybrid mattresses, while back and stomach sleepers are usually better with a hybrid or innerspring mattress.

Overall Quality

The materials that go into making the mattress represent the basis of its overall quality. That means you should look for organic materials like cotton, wool, latex, certified foams, and antimicrobial agents to ensure you’re buying the best mattress in a box.

Support and Firmness

The mattress must provide the proper support and firmness to ensure good health and proper spinal alignment. The mattress firmness scale, which typically ranges from very soft to very firm, helps categorize these levels.

Side sleepers usually do better with medium-firm to soft mattresses, while back and stomach sleepers are better served with medium-firm to firm mattresses.

Size

If you’re sleeping alone, a twin, twin XL, full, or queen-size bed would be good. If you sleep with a partner, small children, or even pets, a larger, king-size mattress (such as a California King or even an Alaska King) would be preferable to ensure adequate room and allow for proper motion isolation.

For larger mattresses, a robust bed frame is especially critical to prevent sagging and maintain mattress longevity.

Off-Gassing Time

Mattresses made with synthetic foams usually emit an odor when unpacked. Depending on the chemicals used in the manufacturing process, it usually takes​​ 3 to 7 days for this odor to disappear.

Even organic latex mattresses emit a mild odor for a few hours, though many people don’t mind. It is best not to sleep on a new mattress until fully off-gassed.

Types of Mattresses in a Box

Mattresses in a box come in various types to suit different sleep preferences and needs. Learn about the most common ones below to make the best decision.

Hybrid

The best hybrid mattress in a box has a memory foam or latex upper layer that conforms to your body. Underneath, a coil spring system provides additional support and better ventilation.

All-Foam

An all-foam mattress is one made with polyurethane foam, or “polyfoam. ” This type of foam is both springy and bouncy and is used in less expensive foam mattresses and as a comfort layer in spring beds.

Memory Foam

A memory foam mattress is made of viscoelastic foam. Unlike polyfoam, it is not springy or bouncy. Instead, memory foam adjusts to the curves of your body to provide pressure relief, motion isolation, and better ventilation while you’re sleeping.

Latex

A latex mattress is a foam mattress made of natural latex derived from the sap of the rubber tree rather than synthetic polyurethane-based chemical foam.

Innerspring

An innerspring mattress has a polyfoam padded surface covering a traditional metal spring coil system underneath for support.

Airbed

An airbed is an inflatable rubber mattress filled with air to the desired firmness. It is usually used as a guest bed and can be deflated and stored when not in use.

Benefits of a Mattress in a Box

If you’re considering a new mattress, a mattress in a box is definitely worth exploring due to these reasons:

Easy Transportation

A mattress in a box is usually rolled up and compressed in a box, making it easy to ship and assemble. No tools are necessary; all you need to do is unpack it and let it decompress.

Affordable

A mattress in a box often represents an excellent price point, making it a fantastic and affordable mattress option. The online sales model eliminates the overhead costs synonymous with physical stores, and the compressed packaging significantly reduces shipping costs.

For those seeking an elevated experience, however, luxury hybrid mattress-in-a-box options incorporate features like cooling gel for enhanced comfort. While these might come at a higher price point, they offer a taste of a luxury mattress experience, including white glove delivery.

Free Shipping and Sleep Trials

Every best mattress in a box included in this article offers free delivery on every mattress in the contiguous U.S., along with extended sleep trials, some lasting as long as a year.

How to Unbox a Mattress

The only tools you’ll need to unbox your mattress in a box are a boxcutter and scissors to open the vacuum-sealed plastic packaging.

Once the box is open, follow these easy steps to unbox your mattress:

1. Bring the box next to the bed.
2. When the box is opened, one person should pull the mattress out while the other holds the opposite end of the box.
3. Unwrap the outer layer of plastic holding the mattress and let the mattress unroll.
4. Lay out the mattress where you want it.
5. Cut open the vacuum seal and let the mattress slowly expand.
