These are what we consider the four best mattresses that cost less than $300 after-discount. For this post, we’re referring to the full size mattress, though, we even have an option that’s under $300 for a queen mattress. And, since we know you’re looking for it, we made sure to include a memory foam bed.

Outline For This Best Mattress Under $300 List

Finding The Right Mattress For Under $300

Typically, we use the queen mattress as our baseline for judging prices, but for this post we felt that the full size was more appropriate. As such, all of these beds sell for under $300 after applying a coupon code or discount. Now that you’re up to speed, here’s our hand-selected list of the best beds under $300:

Even so, we selected beds that we think people will actually enjoy sleeping on. They aren’t luxury mattresses nor do they have any fancy features, but they are good beds, for the money.

Memory Foam Beds, In Particular

It seems like, in particular, people want memory foam beds that retail for under $300. To be frank, there are a lot of options out there, but only a few that are actually worth your consideration—and they’re on this list. You’re not going to get the same feel as if you bought a TempurPedic mattress, but you will be able to tell that you’re sleeping on a memory foam bed and we suspect that most people will be just fine.

Top 4 Mattresses Under $300

Allswell Mattress — Editor’s Choice For Best Mattress Under $300

Why we like the Allswell mattress so much — Pound for pound, we’re not sure that you can find a better value than the Allswell mattress. The bed is made in the USA, has a pocketed coil support system that can handle a variety of sleepers.

It’s so nice, it almost belongs in a whole other tier

Because the top layers of the bed are memory foam and a coil support system, it’s actually easy to rotate positions and also fairly responsive. The bed is on the firmer end of the spectrum, and best for back sleepers, stomach sleepers, and combination sleepers.

Hybrid Construction — In the budget category, there are very few beds that use a coil support system. The Allswell doesn’t use a traditional innerspring chassis. It has pocketed coils, which are much better for isolation motion and yet are still very supportive.

Lucid — Best Memory Foam Mattress Under $300

Why you might consider the Lucid Gel Memory Foam Mattress — Most cheap memory foam mattresses are available in just one firmness level. The Lucid 10″ Gel Memory Foam Mattress can be found on Amazon in a medium-plush, medium, and firm varieties.

It doesn’t look fancy, but it will get the job done

The Lucid 10″ mattress is a non-spring mattress that comes in a soft, medium, or firm option. If you’re a side sleeper, you might think about the plush mattress. If you’re a combo sleeper, you might look into the medium option. And if you’re a back/stomach sleeper, perhaps the firm model makes sense.

While the bed is extremely affordable, it still holds the CertiPUR-US certification, which means essentially that the mattress is safe to sleep on. All of the other beds on this list also have that certification.

Tuft & Needle — Best Foam Mattress In A Box Under $300

What’s so special about the Tuft & Needle Nod mattress — This is a really basic mattress, but we could see a lot of people liking it, especially if you look at the price tag. While the MSRP for the full size is over $300, we regularly see it for under $300. It has a general soft-foam feel that’s comfortable and inviting.

Good option for all sleeping positions

It doesn’t get simpler than a two-layer foam bed, and yet The Tuft & Needle Nod is backed by a 10-year warranty. It might not be exactly what you want in terms of construction, but it has a medium firmness level and will get the job done. We think it’s a wonderful mattress for kids, college students, or anyone that’s smaller or on a tight budget. 

You might not have heard of Tuft & Needle, but they’re a heavyweight in the world of bed-in-a-box mattresses. The company is also backed by (and owned by) Serta-Simmons. We bring this up to let you know that while this is an Amazon-exclusive mattress, it’s not just from some no-name brand.

AmazonBasics — Best Queen Mattress Under $300

What makes the AmazonBasics mattress stand out — It’s all about the price. This is an uber-cheap mattress that sells for under $300. In fact, we regularly see the 8″ version in the queen mattress for under even $200 on Amazon! It’s just a cheap bed that’s pretty comfortable with no extras or anything fancy—just three layers of foam and a slight memory foam feel.

Yes, it’s an Amazon Prime product (expedited shipping)

It does use memory foam, but we wouldn’t consider it to have a true, viscose memory foam feel. Because it has two other layers of poly foam, it has a neutral feel with a little memory foam mixed it. We actually think it’s pretty comfortable, considering it’s very very affordable.

It’s available in an 8″, 10″, and 12″ height varietal. The 8″ model is best for Airbnb, kids, guest rooms, and so on. The 10″ is the most popular and is a direct competitor to Tuft & Needle, Zinus, and Lucid. The 12″ model is better for people that want a little extra padding and cushioning.

Buying A Mattress For Under $300

So you’ve seen most of the bed in a box mattresses on the market and you really aren’t interested in temperature control, hypoallergenic materials, or any of the additional features of a luxury mattress for that matter.

The biggest requirement you have for your mattress is that it’s a comfortable place to rest your head. For whatever reason, whether you’re on a budget or have certain life circumstances that compels you to seek out a cheaper option, the most money you’re looking to spend is $300. That’s okay!

We understand that not everybody needs or even wants to spend extra money on a mattress. There are still options for you out there that won’t break your bank. Many bed-in-a-box brands can offer an affordable/cheap mattress without sacrificing too much of the quality factor. Regardless of your budget, getting a good night’s sleep is still important and we want you to enjoy your mattress as much as you want to enjoy more money in your bank account.

Pros And Cons Of A Budget Bed

Many beds at this price are good quality and offer a good night’s sleep. But they also come with a few disadvantages over higher priced models — such as longevity for example. Continue on below for the benefits and grievances of a budget bed. 


  • Comfort – Budget mattresses can certainly still be comfortable, and wallet-friendly hybrid beds like Allswell provide support for all body types. Budget beds also come in a variety of different materials and feels, such as memory foam, poly foam, latex foam, or a pillow-top. 
  • Localizes movement – Memory foam localizes movement. That means movement will not transfer, so if your partner turns and tosses, you don’t have to, which gives both of you a better night’s sleep. 
  • Durable – It depends on the mattress you get, but budget beds with a hybrid construction are able to withstand the test of time — around 7-8 years or so. All-foam mattresses, on the other hand, won’t offer up as much longevity. 


  • May sleep hotter – Some, but certainly not all, mattresses under $300 sleep hotter than higher-priced models. This may be due to materials used and manufacturing processes.  
  • Support – Some mattresses won’t offer the same level of support that their higher-priced counterparts offer. That may mean that not all parts of your body are evenly supported throughout the night. 
  • Foam compression overtime – Some foam mattresses’ top layers can compress overtime. This may be especially true in some mattresses that are priced under $300, depending on the number of layers and materials used.

Choosing Between A Queen And Full Size Mattress

Size matters. Especially if you’re a 6’3”, 230 pound football player or a petite woman that barely stands 5 foot. Getting the right size bed that gives you the best night’s sleep is important, whether that’s a queen-size bed or a full-size bed.

Full Size

Full-size, also called double mattresses usually measure about 54 inches by 74 inches, give or take an inch or two. They are about the same length as a regular-size twin mattress, but measure about 16” wider overall. A full-size mattress may be a bit too short for taller people, but the added width makes it easier to roll-over and change positions when compared to a twin. But, couples may find it a bit snug to sleep on comfortably.

Queen Size

A queen-size mattress measures about 60” by 80”, but that too can vary a bit by manufacturer. Wider and longer than a double-size mattress, queen mattresses are the most popular by far. Queen mattresses fit into most any bedroom and offer couples ample sleeping space. Queen mattresses are great for people of all sizes: short, tall, and tossers and turners. Queens are also cost-effective and usually priced best.

There’s no denying that the queen mattress is what most people end up with. Over 50% of people end up with a queen mattress. That’s why we made sure to have at least one selection for the best queen mattress under $300 on our list today!

Different Types Of Mattresses

As you can probably imagine, different mattresses are made with different materials, some being more expensive than others. But, what’s the difference?

  • Memory FoamMemory foam mattresses usually have a viscous feel that softens as you apply pressure and embraces the curves of your body. It has a slow response time, but that means it has limited motion transfer so you won’t feel your partner get in and out of bed in the middle of the night.
  • Latex Foam – Latex foam has somewhat of a spongy feel, and has more bounce and breathability to it than memory foam does. Latex foam, however, is usually more expensive and we don’t recommend it for somebody on a lower budget.
  • Polyurethane Foam – Polyurethane foam is widely considered to be comfortable because of its neutral feel. Plus, it comes in a wide range of densities and isn’t too costly. So it is often the safe pick for somebody who doesn’t know exactly what kind of bed they are looking for.
  • Innerspring/Coil – Coil and innerspring mattresses have a system of pocketed or an interconnected spring system that offer good support, particularly for people that are heavier. We sometimes refer to coil beds as being a “hybrid” since they combine two types of materials.
  • Hybrid – Hybrid mattresses are not necessarily a coil mattress. Take the original Purple mattress, for example. That bed uses foam and a Hyper-Elastic Polymer material, which means it’s still technically a hybrid, but doesn’t use coils. The new Purple mattresses (2, 3, and 4) use foam, coils, and Hyper-Elastic Polymer.
  • Hyper-Elastic PolymerHyper-Elastic Polymer is a slab of gel-like material that is bouncy, responsive, and soft. Actually, it’s soft and firm at the same time offering pressure relief where you need it (mostly hips and shoulders) and also support where you need it (your trunk and low back).

Buying Your Mattress Online

There’s little argument that you’ll find the best deals and the best value when you shop for your mattress online. But, before you buy your mattress online, you’ll want to research the different brands to make sure the one you pick meets your needs.

You’ll also want to find out if the manufacturer offers a warranty and if you can return your mattress if it doesn’t work out.  Most mattresses that you buy online offer a risk-free trial period that can range from one month to one year. That gives you the peace of mind that if the mattress doesn’t offer as much support as you need or you end up falling off the side when you sit down to get dressed, you can return it for a full refund (often minus shipping).

And, because you’re buying your mattress online, don’t forget to take the time to read reviews about the mattress and call the mattress company to be sure it is what you want and need.

Why Weight Is Important When Choosing A New Mattress

When it comes to choosing between a firm mattress, soft mattress, or somewhere in between, you should first consider your weight and how well the mattress you select will support you. Your mattress will also last longer if you purchase one that accommodates your weight. Let’s bring back the college student and little kid examples from earlier.

Heavy Body Types

You’re a college student moving out of your freshman dorm into your new apartment, but you’re a basketball player who stands at 6’3 and weighs 230 lb. Your sister’s best friend tells you about a new bed she purchased for a low price, and mentions to you how firm it feels and thinks you may like it too. You go to try it out, and “firm” is the last word you would use to describe the mattress. Your sister’s best friend isn’t wrong for thinking the mattress was firm, she just weighs a substantial amount less and what may be firm to her isn’t considered firm to you. This is because the heavier you are, the more pressure your body applies to the mattress. The basketball player may want to pass on the medium-firm beds and go straight for a firm mattress.

Petite Body Types

On the opposite side of the spectrum is the young boy who says he’s too old for his racecar bed and wants a bigger mattress. He still hasn’t gone through puberty yet because he’s only nine, and he only weighs 65 lb. He is a back sleeper so you want to get a (somewhat) firmer mattress to make sure his body is properly supported, but since he weighs so little, a mattress that lands at a medium (rather than a firm) on the softness to firmness scale would probably be a good fit for him.

Mattress Toppers

Maybe you’re completely fine with spending $300 on a mattress, but after a year of sleeping on it you notice a difference in the way the mattress feels. Or maybe not much has changed in the feeling of your mattress, but you have some money saved up and want to make your mattress a little comfier for you. You always have the option of purchasing a mattress topper such as the Layla Mattress Topper to add more pressure relief or support to your body while you sleep. You can find a large selection of different mattress toppers on Amazon (including the Lucid Mattress Topper) to help you achieve whatever end result you want, whether it be a softer mattress or a firmer mattress. They also have different sized mattress toppers that usually range between 2”-6” so you can make your bed slightly thicker, or significantly thicker depending on your preference.

Caring For Your New Mattress

Just because you don’t spend a ton of money on your mattress doesn’t mean you won’t want to keep it around for a while. Maybe you want to keep it as a bed for your guest bedroom, or as an extra mattress to have in storage for a rainy day. Whatever the reason, there are different ways to make sure your mattress stays in good shape. You can purchase a machine washable mattress protector on Amazon that’s easily removable to throw into the washing machine any time it needs a good cleaning. Most beds don’t come with a machine washable cover, and some don’t even come with a removable cover. Many brands may claim you can remove the cover, but it can be difficult to put back on so we recommend you don’t even mess with it.

You’re also able to spot clean your mattress by using a mild detergent, warm water, and a cloth. Make sure to not get your mattress too wet, though, because you don’t want to do any damage to the foam in the process of cleaning. You may not be able to completely remove every stain, but spot cleaning will at least make it so you don’t have to sleep on top of a big glob of coffee after an accidental spill. Make sure to wait until the spot is completely dry before putting your sheets back on the mattress.

Will I get free shipping?

In almost all cases, yes, you’ll get free shipping, even with a mattress that costs under $300.

What type of mattress is best?

That just depends on the person. If you want more of a traditional innerspring feel, then get a bed with coils. It will all come down to personal preference.

What happens if I need to return my new bed?

That shouldn’t be an issue. Many of the beds sold online come with 100% free returns. That said, returns through Amazon can be a little wonky, so you’ll want to read more about that particular bed on Amazon.com before you make a purchase.

What is a bed in a box mattress?

This is just an online mattress that happens to ship inside a cardboard box. They’re pretty neat, and growing tremendously in popularity.

Will my mattress-off gas?

Likely. Most foam mattresses have off-gassing when you first open the packaging. But, this problem doesn’t last long and seems to dissipate rather quickly.

What’s the difference between poly and memory foam?

Generally, memory foam is much denser than most poly foam. Memory foam has a low-compression factor so it forms to your body more and is slower to rebound than poly foam.

Should I purchase online or in-store?

Buying a mattress online is convenient and can save you money. But, you can’t actually test out the mattress first like you can when you visit a showroom. However, with the extending warranties and trial periods that most online mattress companies offer, you have the peace of mind that you can return the mattress if it doesn’t work out.

Which mattress is most affordable?

Of the mattresses we tested, the AmazonBasics mattress is the most affordable and stood up well in terms of comfort. It also ships free (to most locations) and has a one-year warranty.
