A firm mattress can keep your spine aligned and help you sleep better. But with so many options available, how do you decide which one is best for you? Read on for the answer.

How Firm Is a Firm Mattress?

Your body weight, body mass, and sleep habits determine how firm a mattress feels to you. You can use the mattress firmness chart to help you judge.

Here's a breakdown:

  • 1–2 firmness
    Mattresses in this range aren't firm. Most people won't feel any "push back" when lying down.

  • 3–4 firmness
    You'll get soft comforting layers on top with a more supportive base layer. The base layer keeps the spine aligned.

  • 5–7 firmness
    These mattresses are the most common firmness level for universal comfort (mattresses good for any sleeper). You get comfortable contouring with a bit more support. These mattresses also bounce well.

  • 8–10 firmness
    These are the firmest mattresses with little to no sinking. This level can cause pressure point issues for side sleepers but can be great for heavy sleepers.

Can a mattress be too firm?
Firmness between 5 and 7 (closer to 7) typically provides the perfect combination of firmness and comfort. Anything firmer and it may feel like you are sleeping on the ground.

Best Firm Mattress for Side Sleepers: Leesa Hybrid Mattress

Side sleepers need a perfect balance between firmness for your spine and contouring for pressure points.

The Leesa Hybrid Mattress offers:

  • 1,000 pocket springs for firmness
  • Memory foam layer for your hips and shoulders
  • Breathable top layer to avoid overheating
  • Little motion transfer

Leesa provides a 100-night risk-free trial. They ask that you try the mattress for at least 30 days before deciding. You can buy them online or in person at Pottery Barn and West Elm stores.

Best Firm Mattress for Stomach Sleepers: Saatva Classic Firm Mattress

Stomach sleepers need to lie on top of the mattress. If you sink in, your spine will suffer and you may wake up with back pain.

The Saatva Firm Mattress is a high-end mattress at a much lower price than you'd find in brick-and-mortar stores. It has a firmness rating of 8 and offers:

  • Back pain-relieving technology

  • Organic cotton cover or breathability and coolness

  • Coil-on-coil innerspring structure

  • Dual edge support system that provides more sleeping space and less sagging

  • Firm foam top to provide support for stomach sleepers

Saatva offers a 120-day risk-free trial. They also provide free white glove delivery, which means a personal delivery and setup of your mattress. They even remove your old mattress for you.

Can a firm mattress cause lower back pain?
Yes, a mattress that is too firm won't support your pressure points. If your pressure points aren't supported, your spine may go out of alignment. This may cause lower back pain.

Best Firm Mattress for Back Sleepers: Tuft & Needle Original Mattress

Back sleepers need a firm mattress that will contour their body and keep the spine in line. The T&N Original Mattress has a medium firmness.

It offers:

  • Graphite and ceramic gel to help wick heat away from your body

  • T&N Adaptive Foam that provides durable support for the spine

  • A soft cover that provides both breathability and durability

  • Ideal for any sized sleeper, whether lightweight or heavyweight

  • Compatible with any frame, foundation, or box spring

Tuft & Needle offers a 100-night trial with a money-back guarantee. You can buy T&N mattresses on T&N's website, Amazon, or in-store at Lowe's as well as Crate and Barrel.

Best Firm Mattress for Back Pain: Amerisleep AS2

If you suffer from back pain, a quality firm mattress is a must. While a mattress may not cure your back pain, it will provide the support you need for a better night's rest.

The Amerisleep AS2 offers:

  • Medium firmness with a foam layer for cushion

  • Cooling layer with an open-cell structure to keep heat away from your body

  • Transition foam with zones to provide relief where you need it, like your lower back

  • Plant-based foam that won't sag

  • Foam that bounces back fast, making it easy to change sleeping positions

Amerisleep provides a 100-night risk-free trial. If you decide the mattress isn't right for you during that time, you'll receive a full refund. Amerisleep will also pick the unwanted mattress up for free.

Best Luxury Firm Mattress: DreamCloud

The DreamCloud Luxury Hybrid Mattress has just enough firmness and cushion to keep you comfortable. Measuring 15 inches high with a combination of foam and innersprings, you get the best of both worlds.

The DreamCloud Luxury Hybrid Mattress offers:

  • Great support for combination sleepers

  • Cushions for the pressure points

  • Ease of movement

  • Stable base layer and innerspring-pocketed coils to provide a firm base with little motion transfer

  • Gel-infused memory foam to provide pressure point relief

  • Euro top for a luxurious relaxing feeling when you lie down on the mattress

  • Breathable material to keep you cool and comfortable

You can only find the DreamCloud mattress online. But the company offers a 365-day trial period to ease the risk of buying before you test it out. You'll also get free shipping/returns and a lifetime warranty.

What can you do if your mattress is too firm?
You can soften a mattress instantly by purchasing a cushioning mattress topper. Make sure the layer you choose is supportive of your pressure points while comforting to your body. This way you get the best of both worlds—a firm base with a cushiony top.

Other Firm Mattresses to Consider

Best Firm Mattress for Hot Sleepers: The Casper Hybrid
The Casper Hybrid mattress is great for any sleep position and especially for hot sleepers. It has an open-cell foam structure that offers breathability combined with pressure-relieving zones. The Casper Hybrid also offers durable springs and superior edge support, making the bed firm throughout the entire surface.

Best Firm Mattress Under $500: Allswell
The Allswell mattress is a great mattress for less than $500. The mattress has individually wrapped coils, two layers of open-cell memory foam, and a quilted top for a medium-firm feel. It comes with a 100-day trial period.

Best Firm Mattress in a Box: Brooklyn Bedding
Choose from three firmness levels and enjoy a two-inch layer of comforting foam, a two-inch layer of firm foam, and a six-inch base of coils. The mattress includes a 10-year warranty and a 120-night trial.

Know a mattress company's trial period
Many mattresses come with generous trial periods. On average, you can try a mattress for 120 days. If you don't like it, you return it/dispose of it with the mattress company's help and get your money back. Some companies, like Nectar, even provide a 365-day trial period.

What to Consider Before Buying a Firm Mattress

  • Budget
    Today, you can find mattresses for almost any price. Know your budget—and sleep needs—ahead of time before shopping.

  • Sleep Position
    Stomach and back sleepers need the most firmness. Side sleepers need some, too. Know your typical sleep position to choose accordingly. You can also use the "mattress firmness chart" as a guide.

  • Body Weight
    Heavier sleepers need a slightly firmer mattress to account for sinking, which causes stress on your spine. This can lead to back pain and other ailments.

Bottom Line

Choosing the right level of firm mattress is a matter taste. Luckily today, most mattress companies offer generous trial periods, especially for online purchases. Take advantage but watch out for re-stocking fees that may take a percentage out of your refund.
