Find The Best Mattress Under $300 Complete Buyer's Guide

Like the Zinus 6-inch Mattress, the 12-inch Green Tea Mattress has many great advantages. First, it is one of the CertiPur US certified products, and uses biofoam. Moreover, while testing this 12-inch mattress, my partner and I found its cooling mechanism superb and, as it kept us cool all night long. This is thanks to its cooling gel foam.

Another feature we found beneficial during our second stage review is motion isolation. The mattress is super effective at absorbing motion vibrations, which ensured we didn't disturb each other getting in or out of the bed. Also, if you have a partner who frequently tosses and turns in their sleep, this is the right mattress to go for.

Though it’s a medium soft mattress, we found the Zinus 12-inch Mattress to be below average in the edge support department. Since I weigh 230 pounds, sleeping near the mattress edge felt uncomfortable. But my partner, who weighs 140 pounds, didn't experience any discomfort sleeping near the edge. Personally, I wouldn't recommend this mattress to individuals with mobility issues—especially those who are scared of slipping off the bed—since it compresses excessively when pressure is exerted at the edges. They are better off with an option that has more structure.

Some other additions to the 12-inch version include layered memory foam and infused green tea extract. The extracts work to keep the memory foam mattress fresh longer, while the first two layers are designed to maximize both support and comfort, while the remaining layers help with keeping you cool. Generally, you’ll find how exceptional the memory comfort layer is once you start using the mattress.

To do this, the first two layers are dense, supporting layers of memory foam. The next layer is a pressure-relieving layer that provokes ventilation and the top layer is designed to conform to your body and promote coolness.

This Zinus mattress is an excellent option for individuals with allergies. This is thanks to its CertiPurUS certified foams that ensure it is free of VOCs or other harmful chemicals.

With a price range of $169 - $500, depending on the size, you can bet that this mattress is budget-friendly. To make your investment worth the price, it comes with a 100-night sleep trial and a 10-year warranty. The company also offers free shipping but to addresses within the Contiguous US.

Zinus mattresses are extremely popular box memory foam mattresses known for their great value and fantastic comfort. This cooling gel memory foam mattress is made of high quality and highly durable memory foam that is CertiPur US certified, meaning the foam has been tested and approved as safe and meets standards for content, emissions and durability.

The mattress also promises to stay fresh longer because of its use of a cooling gel memory foam, which gives you all the comfort features of memory foam without retaining heat. As a hot sleeper, I found this mattress to be super helpful in delivering exceptional cooling relief while shielding me against night sweats. The cooling fabric is an added touch to further help keep you cooling during the night.

As a combination sleeper, I found this mattress spectacularly supportive and comfortable. As I slept on my back, the mattress offered me excellent lumbar support while adjusting accordingly to conform to my curves. The mattress also maintained my spine in a neutral position the entire night. 

During our second stage review, my partner and I tested the comfort level for side sleeping. In this position, the mattress adapted to our curves, as it provided excellent targeted support to our shoulders, knees, and hips. This ensured our sleep was comfortable and uninterpreted the entire night, enabling us to wake up rejuvenated.

When we tested it out for stomach sleeping, I felt a slight strain on my spine and neck. However, my partner, who weighs 140 pounds, slept just fine. Overall, we recommend this mattress to lightweight stomach sleepers, weighing up to 150 pounds.

The Ssecretland mattress is durable, and lasts longer than other innerspring mattresses in its price range due to its construction. It is adjustable to fit multiple bed frames and has two models, a 10 inch and 14 inch.

We have always heard great things about this bed, which is why we want to do a full Ssecretland mattress review. Ssecretland’s hybrid mattress offers support from durable, individually wrapped coils. This is one of the reasons we considered it an excellent option for us because of its inner coil construction makeup. The mattress’s comfort comes from three layers of memory foam over top of the coils that are designed to create a soft, conforming texture.

This mattress under $300 also includes a knitted cover that is extremely breathable and will maximize coolness and comfort during sleep. As a hot sleeper, I loved the cooling relief this mattress had to offer.

As one of the best high-quality mattresses, this model comes with an affordable price tag of $269. Even better, it's available on Amazon. Keep in mind that due to rolling, shipping, and compression processes, you shouldn't use the mattress immediately. Leave it open for at least 72 hours. 

This mattress also met our expectations when we tested it for motion isolation. I didn't feel any disturbance during the night when my partner tossed and turned in bed. 

Since I'm a combination sleeper, I found the mattress excellently adaptive to my movements. On the other hand, my side sleeping partner experienced a perfect balance of comfort and support, which helped relieve pressure from her spine. With a medium firm level, we'd recommend it to stomach sleepers but only those weighing 150 pounds and below. 

If you’re on the fence about this bed, one of the main thing you should consider is the 10 year warranty it comes with. Mattresses are only supposed to last around 8 years or so, so having a 10 year warranty on the mattress should give you a confidence boost, especially when buying online.

This 12-inch mattress from Ashley Furniture promises a body-contouring design to maximize comfort. It is made up of a thick core covered by two layers of memory comfort foam and a breathable cover, a design that will give you both great comfort and support. The two foam layers not only provide comfort, but they also help minimize motion transfer so if you sleep with a partner, you won’t disturb them when you move around.

Motion isolation is one of the aspects this mattress excelled in when we tested it out. We both got in and out of the bed and even made a few tosses and turns, and the mattress did a great job of minimizing motion transfer from one end of the bed to the other. Overall, we can strongly recommend this mattress to couples seeking to replace an old one with a new model.

I really enjoyed the contouring capabilities this mattress showcased when I slept on my back. What's more, it offered excellent targeted support around my lumbar region, which helped maintain my spine in a neutral position.

During our second stage review, we also tested the mattress for side sleeping. With a weight of 140 pounds, my partner found it exceptionally comfortable. This was because the mattress contoured closely to her curves. At 240 pounds, I also found the Ashley Furniture 12-inch Chime Express equally comforting. Plus, we noticed that the close body contouring helped to keep the spine in line with the neck, hips, and shoulders, ensuring overall comfort. Stomach sleepers also stand to benefit from this mattress, but we wouldn't recommend it to those weighing more than 180 pounds, as they risk spinal misalignment.

Also, the foam mattress is completely hypoallergenic, so it’s great for those who are sensitive to certain materials. Use it with or without a box spring on a variety of frames, including wood, metal and platform frames.

While this mattress is great if you’re looking for a thick core mattress that’s great for allergies, it’s also worth noting that this mattress has a relatively short warranty. The warranty is only 1 year, And doesn’t cover everything we generally expect to see from a manufacturer.

This affordable foam mattress promises the high quality of higher-priced mattresses, while also being an affordable one. It is designed to relieve pressure on specific body areas, including shoulders and hips, and support the entire body evenly.

While testing the best mattresses under $300, we were looking for an affordable mattress that offers world-class comfort with an ideal firmness that strikes a perfect balance of comfort and support. Luckily, we came across the PrimaSleep Premium Cool Multi-Layered Mattress. Thanks to its medium firmness level, the mattress conformed perfectly to our body curves. That's why we would gladly recommend it to individuals who need a pressure-relieving choice.

When we tested the mattress for side sleeping, it gave us proper support around the shoulders, knees, back, and hips. As an occasional back sleeper, I felt an ease of pressure around my spine and lower back, enabling me to sleep soundly throughout the night. As for stomach sleeping, the mattress offered me and my partner excellent support. However, personally, I wouldn't recommend it to a stomach sleeper weighing more than 250 pounds.

The great features of this mattress just go to show how great of a memory foam mattress you’re getting for a great price. Speaking of which, this mattress costs as little as $172 on Amazon. Even better, the bed is available on various popular platforms for an even much better price deal.

However, it could still hold my partner, who weighs 140 pounds, so we'd recommend it to light sleepers weighing 130 pounds and below. Also, when we sat at the mattress edge, it compressed down excessively; therefore, we would recommend individuals with mobility issues to seek an alternative with solid edge support.

We also experienced incredible targeted support, as promised by the manufacturer, thanks to the encased coils.
