How Do I Set Up My Leesa Mattress in a Box?

If you're still on the fence about buying a Leesa mattress in a box – whether our original mattress, our budget-friendly Studio all-foam mattress, our hybrid mattress with individually wrapped coils, or our top-of-the-line Legend hybrid mattress – wait no longer. 

Yes, there are plenty of alternatives out there: Brooklyn Bedding, Purple, the Casper mattress, the Nectar memory foam mattress, the Lull mattress, traditional innerspring mattresses, hybrid mattresses, even foam mattresses from the Mattress Firm. 

Which are the best mattresses? There are lots of mattresses in a box, but we firmly believe our organic mattresses are the best – the best value and of the best quality, far above the average memory foam mattress.

OK, you've finally evaluated the various options and (wisely) ordered your Leesa mattress. The wait has been hard. But today, you come home to a box outside your front door thanks to Leesa's free shipping. 

Whoo-hoo! – your mattress arrived. Grab a buddy, bring it inside, and welcome it home.

How to set up your Leesa mattress in a box

First, move your Leesa box to the bedroom. Before you set up the mattress, make doubly sure you have the right bed frame for your new Leesa mattress. To provide you with the proper support and pressure relief when you're sleeping, a Leesa mattress should be placed on a flat, rigid surface, like a platform bed.

If you have a platform base that uses wooden slats, be sure the slats are no more than three inches apart–this gives the Leesa mattress the firmness and support it needs to give you the ultimate sleeping experience. If you have a metal platform frame, you're probably good to go. Pro tip: Leesa also offers bed frames and bases designed to our exacting standards specifically for our high-density memory foam mattresses. 

How to unwrap your Leesa mattress in a box

Only 7 simple steps stand between you and finally achieving sleep nirvana on the best mattress you've ever owned:

Step 1: Open the cardboard box.

Step 2: With the mattress still in its plastic wrapping, slide it onto the surface of your bed frame or base.

Step 3: Proceed with caution! Using a pair of scissors, carefully cut the first layer of plastic surrounding your new mattress, being sure you don't accidentally cut into the memory foam.

Step 4: Repeat, removing the second layer of plastic around the mattress.

Step 5: Unroll the mattress. It will still be tightly compressed and folded in half.

Step 6: Unfold the mattress and while it’s still compressed and still in the third layer of plastic, arrange it on your platform or base. (Don’t open it yet! You'll position it more easily if it's still compressed and sealed.)

Step 7: Once properly positioned, carefully cut away the final layer of plastic around the perimeter of your mattress-in-a-box. Pull the plastic out from under your Leesa and instantly, the base, the viscoelastic memory foam, and the cooling premium top layer of your Leesa mattress will begin to expand, decompress, and fill with fresh air.

How long will it take for my Leesa memory foam mattress to fully expand?

It may be next to impossible to resist diving straight into your Leesa, but now's the time to practice self-control and let your best mattress ever fully decompress before you begin sleeping on it. In an hour your Leesa will feel great; after four hours it’s almost there; but to get the ultimate support, pressure relief, and motion isolation from your memory foam mattress, give it a full 24 hours to decompress to perfection. This is especially true if you or your partner are side sleepers or stomach sleepers. No matter your sleeping position, you will experience a blissful night's rest on your new Leesa supportive foam mattress.

Do I have to put sheets on my new Leesa mattress?

We know, we know – your new bed is so gorgeous. Do you have to cover it with sheets? Each Leesa mattress was intentionally created with a clean design. The single-piece cover of each mattress is made from a buttery lycra-poly blend that is so soft we’ve had people actually say they prefer not to put sheets or a mattress cover over it. But that’s entirely up to you. How much wear and tear will your new Leesa mattress endure? Do you have young kids or pets? Do you sleep hot? Think about how sad you would feel if something stained your mattress purchase.

We prefer using a mattress protector as well as sheets for the optimal sleeping experience – and to protect your investment. By the way, check out our Leesa sheets. If you think your Leesa mattress feels like heaven, you won't believe how these 400-count cotton sateen sheets feel against your skin.

Check out Leesa for all things sleep not just a mattress in a box

Here at Leesa, we pride ourselves on being kind of sleep gurus.

Every Leesa mattress comes with a 10-year warranty as long as the mattress stays in the U.S. or Canada. And for every 10 mattresses we sell, Leesa donates one mattress to a family in need. So, you'll sleep better and do good with Leesa.


Especially if you live in an apartment or condo, disposing of your old innerspring mattress can seem like a daunting task. Relax and take a deep breath – there are several ways to get rid of an old, but still useable, mattress. How can you know it's useable? Common sense:

Don't donate or give away a mattress with stains unless any stains can be removed. Stains from blood or body fluids can sometimes be removed with an enzymatic cleaner or other organic solutions.

Don't donate or give away a mattress with a bed bug infestation!

Don't donate or give away a mattress with strong odors. You may need to enlist someone from outside of the household to take a sniff. It's easy to become nose blind to odors in your own home. 

Don't donate or give away a mattress with protruding springs.

If the mattress is useable, you can donate it to organizations like the Salvation Army or one of Habitat for Humanity's ReStores. Or you can try to sell it or give it away via social media like Nextdoor, Craigslist, or Facebook.

You can choose to recycle your previous mattress. Check with your local recycling facilities or inquire to see if your municipality takes mattresses for recycling. Other organizations to check out include Earth 911 which offers a search engine for local recycling facilities and services, as well as Bye Bye Mattress, a database of recycling services here and abroad.

Just don't chuck your old mattress into the dumpster. The Sleep Foundation says up to 20 million old mattresses wind up in landfills every year.

Note to self: if you add in-home delivery and setup to your Leesa order, we will haul away your old mattress and box spring.

What's the difference between a mattress in a box and a hybrid mattress?

Hybrid mattresses and mattresses in a box are actually the same things! Your Leesa hybrid mattress will be packed safely into a box for easy shipping. You’ll be amazed at how quickly it fluffs up once you remove it from the packaging.

How long can I leave my new Leesa mattress in a box?

Don't wait too long to unpack your new Leesa memory foam or hybrid mattress. You’ll want to get started on your best night’s rest right away. If you must wait a bit before setting up your new bed, your new Leesa Original mattress can stay in the box for 30 days from the date the order was placed. Your new Leesa Sapira Hybrid mattress can stay in the box for up to 60 days from the date the order was placed.

Will my new Leesa mattress in a box smell?

Great question! Just like any newly manufactured item, your new Leesa mattress may have a slight smell after you unwrap it. But, the smell won't hang around. You can rest assured Leesa's organic foams don't give off any harmful chemicals or gasses. Remember: all our foams are CertiPUR-US® certified. Just let your new mattress breathe as much as possible and that "new car smell" will go away in a jiffy.

What if my Leesa mattress gets stained?

We understand life happens. Say your toddler climbs up to snuggle, but with a sippy cup full of fruit juice. Whoops! Or your new puppy has an accident. Depending on the type of stain, Leesa has some fast and natural remedies. Check them out here.

How do I care for my Leesa mattress?

Easy, peasy. About every three to four months, strip your bed and vacuum your mattress using the upholstery attachment. Then, rotate the mattress, top to bottom. Just don't flip a Leesa mattress. And like mom always told you: change your sheets every week!
