Many online mattress companies are hoping to entice last-minute shoppers to give the gift of a good night's sleep to a loved one. Or to yourself.

More on Mattresses

We’re seeing promotions, some valid through the end of the year, on some of the best beds-in-a-box in CR's mattress ratings. "Bed-in-a-box manufacturers tend to roll out their product at a moderate price, then follow up with discounts and promotions," says CR's Claudette Ennis, a market analyst for mattresses. "These firms don't necessarily wait for major shopping holidays—offers are always available."

And while the cut-off for Christmas shipping has passed, most of these companies promise delivery in a matter of days. (See our mattress buying guide if you're not sure where to begin.)

Here’s a rundown of the best deals currently available, in alphabetical order.

Bear

The deal: Now through December 31, you can obtain a $100 coupon code at bearmattress.com if you share your email address. Required minimum purchase is $1,000.

CR’s take: The Bear Queen mattress fared well overall in our tests, though it doesn't score quite highly enough to make our recommended list for foam mattresses. The company's pricing also hits the midrange in this category; a queen goes for $850. That means you’ll have to throw in an accessory, even if you opt for the $950 king-size mattress, to reach this promotion’s minimum. Like most of these companies, Bear offers its own pillow, mattress protector, foundation (similar to a box springs), and bed frame.

Casper

The deal: Casper’s offering $100 off when you spend at least $1,000 through December 26. Use the code “Unwrap” at check out.

CR’s take: Casper’s flagship mattress, The Casper, performed well in our tests and provides a comfortable perch for sleepers of any size, whether you prefer sleeping on your side or back. But, again, the model runs $950 for a queen, so if you’re going that route, you’ll need to purchase another item (a queen-size mattress cover goes for $85; pillows start at $55) to meet the minimum.



Cocoon By Sealy

The deal: Save $75 on Sealy’s bed-in-a-box play, or get $125 off any mattress and foundation set. For queen, across the board, prior to discount: The Cocoon Classic mattress costs $800, the Cocoon Chill goes for $950, and the Cocoon by Sealy foundation is $300.

CR’s take: You can order the Cocoon Mattress in two variations: Soft or Firm. We tested the Cocoon Firm, which received a 6 in our Firmness test (on a scale of 1 to 10, 10 being the firmest). Our tests reveals that it provides adequate support for a petite sleeper, whether they prefer to sleep on their side or back. But it doesn't perform as well for average or large/tall sleepers.

GhostBed

The deal: Get $100 off your mattress order, plus the company will throw in two free GhostPillows. The pillows normally retail for $85 each.

CR’s take: The standard GhostBed earned a respectable spot in our mattress ratings. It's one of the firmer top-performing beds-in-a-box we’ve tested, and it provides adequate support for sleepers of all sizes, whether you sleep on your side or back. The discount means this already-affordable GhostBed comes down in price to $695 for a queen. And if you need new pillows, this promotion provides a nice value.

It Bed by Sleep Number

The deal: Between now and January 2, 2018, Sleep Number’s marking down its adjustable air It Bed by $100. This bed-in-a-box only comes in queen, king, and California king, and normally starts at $1,099.

CR’s take: While it doesn’t score as highly as most foam beds-in-a-box, this adjustable air model did receive top marks in Durability. In terms of support, though, it’s not a standout. The two other Sleep Number models we’ve tested, the Sleep Number i8 and the Sleep Number c2, on the other hand, receive high marks.

Leesa

The deal: For Leesa’s Holiday Mattress Event, the company’s discounting the Leesa mattress by $100 and throwing in one free standard pillow (normally $75). The promotion is applied automatically and goes for any size of The Leesa Foam or the more expensive Sapira Spring.

CR’s take: We’ve tested the Leesa Medium Firm, and indeed, it scored a 5 in our Firmness test (where each mattress is rated on a scale of 1 to 10, 10 being the firmest). Better suited for smaller folks, the Leesa earns a Very Good in our Support tests for petite sleepers; its score is lower for average and large/tall sleepers.

Novosbed

The deal: A $100 promo code is automatically applied at
checkout. When we added a few mattresses to our cart, the company knocked off $100 for each model, even twin-size mattresses.

CR’s take: Much like the Bear above, the Novosbed falls just shy of the top tier in our mattress tests. And, similar to the Leesa, it provides exceptional support for petite back sleepers and great support for petite side sleepers.

Purple

The deal: When you buy any Purple mattress, the company's tacking on a free seat cushion, normally $40. The freebie is called the Everywhere Purple Cushion, which you could use in the car, at work, at a ball game, etc.

CR’s take: We found The Purple Bed provides solid support for petite and average sleepers but only middle-of-the-road support for average/tall sleepers. It’s not as firm as some of its competitors, but if you prefer a softer mattress, it’s worth consideration. The freebie, a $40 value, is part of a collection of seat cushions made of the same gridded elastic polymer that’s in Purple mattresses. For every mattress you add to your cart, the seat cushion should automatically appear.
