Getting a quality night’s sleep on a regular basis is absolutely vital in maintaining an optimal level of health. A big part of being able to achieve that restful state of bliss reliably comes from the mattress that you lay down to rest on each and every night. Investing in a firm mattress, in particular, is one of the best ways to ensure a solid night’s rest. For some people, the more firm the mattress, the better. Luckily, purchasing one is as easy as clicking a few buttons online. Hence, we narrowed down the very best firm online mattress options perfectly suited to get you well on your way to achieving those coveted eight hours of sleep. 

FIRMNESS GUIDE

Not all firm mattresses are created equal. Thus, when looking at the most firm we consulted the Sleep Advisor’s firmness scale. The scale ranges from 1 to 10, with 1 being the softest and 10 being the firmest. Take note, for the purposes of this guide we only looked at mattresses that rated 7 or above on the firmness scale. 

WHO DOES A FIRM MATTRESS BENEFIT MOST?

Before diving into the best firm online mattress options, it’s important to understand why choosing a firm mattress might be ideal for you. Preferring a firmer mattress over a softer one can, in some cases, simply come down to personal preference. However, for certain individuals having a firm mattress can provide added benefits apart from just aiding in your overall nightly comfort level. For instance, the Sleep Foundation reported that a firmer mattress is typically a great choice for an individual who is larger in stature because it has the capability to offer much better support than its softer counterparts. Generally, the firmer the mattress the more support you can expect. 

Additionally, those with neck and back injuries or weaknesses can also greatly benefit from the extra support that a firm mattress is able to deliver. This is because firmer mattresses do not sink or sag as you sleep throughout the night. This means that you won’t put any undue pressure or cause any strain on injured or sensitive areas. 

Moreover, even for those without any injuries or pain to speak of, a firm mattress can do wonders in helping back and stomach sleepers achieve a good night’s sleep, as well. The benefits of opting to invest in a firm mattress are clearly undeniable whether it’s because you simply feel more comfortable sleeping on one or because of the fact it can aid you in alleviating unnecessary pain upon waking. All that being said, let’s dive into the best firm online mattress options. 

SAATVA CLASSIC MATTRESS

Firmness Rating: 7 (Medium-Firm) and 9 (Firm)

WHY IT’S THE BEST – The Saatva Classic’s well-deserved award-winning status easily makes it one of the best firm online mattress options to choose. The Saatva Classic comes in two different firmness options – Medium-firm or firm. The medium firm option rates at a 7 on the firmness scale whereas the firm option slides in at a solid 9 out of 10. 

This firm online mattress is a unique hybrid model comprised of innerspring coils, latex foam, and a cushiony pillow top. The medium-firm level was designed to be reminiscent of the kind of bed you would sleep on at a luxurious hotel. It is the ideal choice if you tend to sleep on your stomach or back and is also the perfect compromise for couples who have differing opinions on just how firm or soft their mattress should be. 

The firm option, in contrast, is for those who are looking for a mattress with absolutely no give in order to completely mitigate any possible feelings of sagging or sinking into the bed. It is ideally suited to offer optimal support to those with larger body types as well as those back and stomach sleepers with underlying injuries or sensitivities. What’s really great about the firm option is that its pillow top still provides enough comfort to ensure you don’t feel as though you are sleeping on a hard surface.

HELIX PLUS

Firmness Rating: 8

WHY IT’S THE BEST – If you are looking for the absolute maximum in overnight support from your firm online mattress, then the Helix Plus should be among your considerations. The Helix Plus is a thick (13 inches) hybrid mattress with a unique build profile meant to stand the test of time. It is comprised of wrapped coils and layers of dense memory foam that contribute to the overall 8 out of 10 firmness rating. However, what really makes the Helix Plus unique is the inclusion of 4-inches of high-density memory foam. 

The high-density memory foam characteristic makes it possible for this mattress to support you adequately while still cushioning areas of your body (like your hips) less inclined to benefit from stark firmness. The Helix Plus also features superior motion isolation. Meaning that it would make for a great choice for couples who like a firm mattress because you are less likely to feel your partner move during the night and potentially disturb your sleep.

PLANK MATTRESS

Firmness Rating: 9

WHY IT’S THE BEST – Plank’s website describes this mattress as “firmer, flatter, and flippable.” Those characteristics all combine together to create the pinnacle representation of what a firm mattress should be. The mattress is comprised of four individual layers that all add to the superior support that it delivers. The layers include a 3/4 inch quilted top, 7 inches of high-density foam, 2 inches of Titan Flex comfort foam, and a 1.5-inch quilted bottom.

 However, what’s really great about the Plank is that it is flippable which is perfect for when your need to adjust your firm sleeping needs. If you choose to sleep on the 3/4” quilted top then you can expect an ultra-firm and flat sleep experience ideally suited to help your spine into a neutral position. This spine adjustment allows you to breathe in a greater amount of oxygen as you snooze. This might help to alleviate some issues that chronic snorers face. The flip side delivers the same experience with a slightly more contouring feel. Also, if you tend to sleep hot you can opt to add a PCM surface infusion of TitanCool to ensure you’ll never wake up sweaty again.

WHY IT’S THE BEST – The Ghostbed Flex Hybrid is a perfect online firm mattress option for those looking for a sleeping experience akin to what a traditional inner-spring would provide.

It is built upon its foundational high-density support layer, followed by a layer of individually wrapped coils. The proprietary “Ghost Bounce layer” is the 3rd up from the base and is meant for the sleeper to feel as though they are floating while they rest. 

The other layers include two separate sections of gel memory foam, a woven cooling fiber cover that is topped by a cooling quilt. All of Ghostbed’s features mesh together to seamlessly facilitate a quality night’s rest that is enhanced by its cooling capabilities, motion-isolating properties, and a propensity to make you feel lighter than air as you rest.
