12 Best Mattresses For A Platform Bed In 2021

When you buy a new mattress, you might also need to replace the box spring. Most people think of the box spring as the only option for mattresses, but there are other options out there.

One of them is a platform bed. A platform bed is a mattress platform with the mattress resting directly on it. It’s also known as a slatted bed or an open frame. If you have a low-profile mattress, this is your best option because there’s no need to add height to accommodate the mattress.

For most people, having no box spring means that they’ll get a more comfortable sleep, especially where back pain is concerned. I tried really hard to help you pick the best mattress for platform bed in 2021. Stay tuned!

About my research

I spent 97 hours conducting this research and pick the best mattresses for a platform bed. I looked at 100 different platform bed mattresses and narrowed them down to 12. I first looked at a number of individual mattress models before shortlisting the best options available today.

I looked into various factors such as the construction, price, durability, customer reviews, return policies, warranty information, and more. With all these in mind, I selected 12 that I think are among the best suited for you if you’re looking for a new mattress for your platform bed. I consulted an orthopedic surgeon Bernard Yakorsky about the most overlooked things to keep in mind when choosing a mattress for a platform bed.

Bernard Yakorsky said:

“From an orthopedics point of view, a mattress should be firm, yet comfortable to avoid pain and discomfort. It should offer great support for your back and not make you toss and turn in your sleep. “

Also, I consulted with Elsey Nijovich, CCPMA. She game be general recommendations and helped with reviewing several models.

Also, I surveyed our community and asked them a series of questions about what kind of mattresses is optimal for a platform bed. Here’s the list of questions they were asked:

1. What is the most important feature that you look for when buying a mattress?

2. What are the main things people should pay attention to while shopping for mattresses?

3. Are there any specific features that can ruin your sleep if they’re not properly addressed or handled?

4. Do you think it’s worth investing in quality bedding and mattress at the beginning of establishing your life together as opposed to buying something cheap but good right from the start?

5. Would you recommend getting an adjustable bed frame (a bedframe where each side can be adjusted separately)? If so, why would you do so? If no, why wouldn’t you do so?

Also, I contacted the customers who are looking for a mattress for a platform bed and asked them to check this guide. Here is feedback from Ben Kirsty:

“I have to agree with the findings of this article. I was actually looking for a new mattress for my platform bed and found it very difficult to choose one because there are so many different models from different brands, sizes, prices, etc., out on the market today. If you’re in the same situation that I was then look no further because you’ve come across exactly what you need.”

All this information has helped me to create a valuable, fact-checked guide for choosing the right mattress for a platform bed.

Top mattresses for platform beds in 2021:

Original Nectar mattress

A Nectar mattress is a perfect combination of durability for pressure relief and support that makes your sleep really comfortable.

Nectar mattress is one of the best mattresses available for platform beds because it is made from materials that breathe, and this mattress sleeps really cool. It also does not contain any chemicals that can harm your health.

Here is what an expert orthopedic surgeon Bernard Yakorsky says about Nectar mattresses:

“I’ve been recommending them to my patients for years because of their pressure-relieving support and unparalleled durability.”

Here is how I tested the Nectar mattress in our testing lab:

I replaced my sleeping mattress with another one every 30 days throughout the year. Every day I scored the quality of sleep which resulted in a total score for each mattress. Nectar mattress had the highest score among all options for a platform bed.

Here go the quantitative measurements of this product:

1. Durability   (10)

2. Back Pain Reduction   (9, 6 out of 10): it relieves back pain and helps you to sleep on your side without triggering pressure points. It also has a cooling and breathable material which is perfect for summer nights when you don’t want to be suffocated by the heat.

How Nectar Original has evolved from previous models:

Because the mattress is made of all foam, and some people tend to sweat more than others while sleeping, it’s better to have that light layer to avoid direct contact with the mattress.

The thickness has been increased as well against previous models by half an inch.

How Nectar Original was designed:

Delivered rolled in a box, Nectar Original is easy to unpack.

It’s designed with a memory foam layer that allows the mattress to bounce right back after you get out of bed.

Pros And Cons Of Platform Beds

Compared to regular beds, platform beds have no box spring. This is both a pro and a con depending on how you look at it. The biggest advantage of this mattress type is that it’s more affordable than most mattress platforms and they are also lighter because there’s no need for reinforcement to hold up the mattress. On the other hand, because there’s no box spring between the mattress and the frame or floor, some people find it harder to sleep on a platform bed mattress because of issues with springs poking through even if they’re covered in mattress pads or mattress protectors.

Pros of Platform beds: 

– Most mattress platforms are easy to assemble which makes them easier to move as compared to regular beds.

– Because they have no box spring, there’s less need to reinforce the frame or floor for mattress support which makes platform beds much lighter.

– The absence of springs at the top layer means that mattress pads and mattress protectors can be used without having a mattress that feels too rigid and firm.

Cons of platform beds:

– Many mattress platforms are somewhat flimsy which means that using mattress pads and mattress protectors can cause sagging.

– Consumers Report that mattress platform beds may not be so ideal for couples because they tend to sag in the middle due to added weight as compared to mattresses placed on a standard box spring bed. 

At the end of the day, only you should decide if the platform bed mattress is right for you. But with mattress platforms bringing in the versatility that mattress pads and mattress protectors can offer, you may find that mattress platform beds are a great option for anyone looking to make their mattress more comfortable.

Frequently Asked Questions

How to keep the mattress from sliding on the platform bed?

It’s important to choose the right size of the platform bed since it will allow an entire mattress to rest properly on it and not shift. The common sizes are King, Queen, Full, Twin, and California King. Also, you can use bed rails and corner posts in order to keep the mattress from moving.

You can even check special slats that are designed for bed placement on a platform bed. A standard set of slats will work well, although it may result in some gaps between them.

What kind of mattress is best for a platform bed?

There are multiple cases of mattresses that work well for platform beds, but the most popular ones include memory foam and innerspring.

Although a memory foam mattress is preferred for this kind of bed, an innerspring one could also be used as long as it’s firm enough to keep its shape upon use and not sag over time. Also, choose these kinds of mattresses if you’re looking for a new piece and want to avoid the hassle of moving a heavy mattress alone. Also, there are hybrid mattresses that combine two types of materials – memory foam and innerspring, which are also an option for you.

As for the thickness of a mattress to buy, go for somewhere between 8-10 inches, although you can be more lenient if you plan on incorporating a foam or latex topper. Basically, a mattress should be wide enough so that it doesn’t sag over time when used with a box spring or other frame support.

How to raise a mattress on a platform bed?

To raise a mattress on a platform bed, you’ll have to get a strong mattress foundation first – preferably one made of solid wood. The end goal is to protect your bed frame from sagging and keep the mattress off the ground, and this solution will definitely deliver in both aspects.

Alternatively, if you want to save some money on a new piece, you can just build up your existing bed frame with slats (2″ or wider) by following DIY instructions that are easily available online. Another option is getting pocket-sprung slats which are much thinner than regular ones and will be more suitable for beds with headboard attachments. Just remember not to outdo yourself because it could lead to an unnaturally bouncy feel when resting.

Can you put a regular mattress on a platform base? 

Many users find that their regular mattress and box spring combo are too thick for this type of bed frame. If you have an old leather-bound classic bed with a very high headboard, then it would be impossible to put any type of foundation underneath it — the thicker the shorter wall is, the worse this problem is as well.

Can I use a sheet of plywood on a platform bed?

Many mattress manufacturers recommend that you use plywood, but it does not seem to be the most reliable choice for some people. The purpose behind this is that if using a box spring with a metal frame, then there is extra weight on top of the bed and it could be an absolute disaster if the plywood cracks under the strain.

Wooden slats can create more gaps for things to fall through as well. Some users still swear by sheet plywood though; they usually have better success when cutting small notches in each piece so they fit around the slats securely without being too tight or giving support.

What type of mattress is best for a children’s platform twin bed?

There are a lot of options available out there, but the best one for your child is really up to you. You’ll want to decide how firm or soft you want the mattress to be and then look at what else it has going for it. Will they play on their bed? Will they jump on it? What size is their bedroom? All of these things should factor into your decision about which option will be best for them. However, most kids will enjoy a hybrid two-sided mattress.

What is the best mattress for a platform king bed?

The best mattress for a king-size platform bed is going to be one that has a thick foam side. Many people choose these mattresses because of their softness, but they are not as good when it comes to supporting your body night after night. More than likely you will get sore if you sleep on them every night.
