The knit cover is also removable and washable, so should you create a mess with your late-night snacking, it won’t be a problem.

Sealy: The Brand

Founded in 1881 by Daniel Haynes in Sealy, Texas, Sealy started as a small business with Haynes making cotton-filled mattresses for his friends.

In 1889, he invented a machine that compressed the cotton, and then licensed the invention to others so they could make “mattresses from Sealy.”

Today, their mission is to create beds that will last for years, which are also comfortable and supportive.

In their product line-up, Sealy also offers innerspring, memory foam, and hybrid mattresses.

The Positives


Multiple users of this Sealy mattress noted how comfortable it is. It’s not hard to imagine why, since you’ll be relaxing on just over eight inches of memory and conventional foam.

Additionally, with a medium-firm feel, the bed is thick enough to provide support while also soft enough to deliver luxurious, plush comfort throughout the night – no matter your chosen sleeping position.

The conventional foam also helps promote airflow and breathability, so the mattress won’t grow too hot during those summer evenings.


The layers of foam and the medium-firm composition result in a supportive mattress for those with joint and back issues. Because there are no springs in this bed, the pressure on your body will be greatly reduced.

The foam conforms to your shape and supports your back, neck, and sides. Whether you prefer a new sleeping position every night or have an old favorite, you’ll find the bed tailors itself to fill in gaps and cradle your body.

As a plus, there’s no worry of sinking in. The conventional foam provides a base layer that limits sinking, ensuring it will bounce back and continue to adjust for a long time.

Easy to Clean

The Sealy 8-Inch Bed in a Box Mattress also comes with something not many traditional beds include: a washable, removable cover!

If you get any stains on the mattress (from an accident or a midnight snack), you need only remove the cover and throw it into the washing machine.

No need to invest in a protective cover or resist eating in bed. Sealy made sure that clean-up is very easy.

Easy Set-Up

Getting a mattress set-up in your house can be quite the task, but you don’t have to worry about the Sealy Bed in a Box.

In this regard, it truly lives up to its name. No need to schedule times for your mattress to be delivered. Once it arrives through the regular mail, just bring the compact box into your house and into the bedroom.

Then, slip the mattress out of the box. It will be rolled up. Place it on whatever frame or box spring you choose and unroll it.

Carefully cut the plastic, shipping labels, or other materials off the mattress, and watch as your new bed rises and forms into its normal shape.

It may take up to 24 hours, but most users said it required less than eight hours to fully expand.

10-Year Limited Warranty

The mattress also comes with a 10-year limited warranty. So, for 10 years, any problem with the mattress that is due to the manufacturing or a problem with the materials will be covered.

You’ll get a refund, have your mattress fixed, or get a whole new mattress. The bed also must have been purchased from an authorized retailer of Sealy mattresses.

The warranty doesn’t cover your comfort preferences, any damage you do to the mattress, if you buy a floor model, or if you place it on an improper base or foundation.


One of the very best things about this mattress is the price. Sealy stands up with the best in bedding brands in the business, but they’ve opted to make the Sealy Bed in a Box affordable and easily accessible.

Those on a budget won’t have to dig too deep into their savings, and those looking for a temporary or occasional bed won’t have to shell out a ton of money on a mattress for just short-term use.

The included warranty takes a lot of the risk out of the purchase too, so all you have to worry about is getting this mattress on your base.


The Sealy Bed in a Box can be placed on any foundation of your choosing. This means that you won’t have to upgrade your base along with your bed, saving you money and effort.

If you have an adjustable frame, no need to worry either, the Sealy Bed in a Box will fit.

This is great if you’re looking to place this mattress in other unconventional places like a camper or a dorm room.

With a variety of sizes to choose from, you’ll be sure to find the one that works the best for your situation.

The Negatives


Almost every user noted that the mattress has a strong chemical smell when you first take it out of the packaging.

Most likely, the smell will go away after a few days, but if you are especially sensitive to odors, you may want to let the mattress air out in a different room before attempting to sleep on it.

As such, avoid placing it on the foundation of your choice and find different sleeping accommodations for a night or two.

If odors are really an issue for you, a memory foam mattress is not the right buying decision. Most of them come with this smell, and it fades after a few days.

Takes Time to Get Used to

A few users also mentioned that it required a couple of days to a week in order to adjust to sleeping on a fully foam mattress.

This may not be a problem for everyone. If you’ve slept on a memory foam mattress or something like it before, you shouldn’t have an issue getting used to it.

However, if you’ve only ever slept on an innerspring mattress, it may require an adjustment period as you adapt to the softer, less bouncy material.

Too Thin

This was not a complaint with too many people, but it’s worth mentioning nonetheless. Some users discovered the mattress was thinner than they expected.

While it’s described as eight inches thick, that density didn’t provide the level of comfort or support a few testers needed.

One user even mentioned that it would best serve as a topper for a secondary mattress, but could not suffice as a standalone bed.

If you check the measurements and see how they compare to the mattress you have now, you shouldn’t be too surprised with the thickness of the Sealy mattress. Though if you’re used to a thicker bed, this may feel very different to you.
