So, you’re in the market for a 6” mattress? Then you’ve come to the right place!

This guide will cover everything you need (or ever wanted to know) about 6-inch mattresses, and what to look out for when shopping for one of your own.

More than that, our expert team of mattress specialists has put in hundreds of hours of sleep vetting the best 6-inch mattresses to buy online saving you time, effort, and frustration by highlighting our top 3 picks.

Will a 6-Inch Mattress Have Enough Support?

Certainly! With the right layering of high-density support foam, memory foam, or comfort foam, a 6-inch mattress can effectively support most individuals!

Is a 6-Inch Mattress Comfortable?

Comfort is in the eye or rather the back of the individual.

6-inch mattresses can indeed be comfortable, but, as mentioned above, it’s important to get the layers right.

If the mattress does not have enough support, you will suffer from lower back pain. But on the flip side of that, too much support and not enough comfort will feel too stiff and firm.

Balancing the layers becomes extremely important when building a thin mattress.

What to Consider Before Buying a 6-Inch Mattress

Use

How, where, and how frequently do you intend on using your mattress?

Of course, we’d all like a premium mattress with all the bells and whistles at our beck and call for the night’s sleep.

However, it might not make much sense to splurge on a top-of-the-line mattress that’ll only be used on occasion.

Materials and Build

Each type of mattress material from latex and high-density foam, to gel foam and memory foam all have differing benefits, levels, of comfort and levels of support.

Similarly, the build itself can make a world of difference.

Cost

Going as cheap as possible won’t get you much more than the lowest-grade foam (you know the kind the cheap yellow foam that has no support to speak of).

Similarly, buying the highest priced mattresses might leave you with a great mattress but a not-so-great bank account.

Luckily, MattressInsider specializes in high-quality mattresses that won’t cost you an arm and a leg!

Warranty

Although not the end-all be-all, a strong warranty is a good indication that the company stands behind its products.

It can also be an indication of the quality of the materials used.

Do Mattress Companies Make 6-Inch Mattresses?

In short, yes. But that’s about as thin as it gets with the exception of a custom mattress.

Why is 6” generally the thinnest you can buy online? Because mattresses achieve the desired level of comfort, support, and firmness from uniquely engineered layers of foam and other types of materials.

The thinner you go, the more difficult it becomes to achieve the desired effect.

Popular Types of 6” Mattresses

6-Inch Twin Mattress

Sometimes called a ‘single’, the 6” twin mattress is often the perfect transitional mattress when toddlers outgrow their crib and need a bed.

These mattresses are also great space savers for those living in apartments or dorms, and are ideal for single adults who sleep alone and don’t need a lot of room to roll around.

6-Inch Full Memory Foam Mattress

Originally developed for use by NASA, memory foam has since made its way into our furniture and beds.

Known for its unique feel, pressure-relieving capabilities, and arguably unbeatable comfort, its no surprise that memory foam mattresses rank popular among 6” options!

6-Inch Folding Mattress

One popular option with 6” mattresses is the folding mattress.

These are ideal for space-saving, storage, travel, kids’ sleepovers, visiting family, and more!

What Is a 6 Inch Mattress Used For? The Best Applications and Ways to Use Them

Bunk Beds

The thinner profile of a 6” mattress is often ideal for ensuring adequate headroom and space between the bottom bunk and the top bunk, and to ensure there is enough room between the top bunk and the ceiling of the room.

Daybed

The slimmer style of a 6-inch mattress is useful for daybeds when additional room for lounging and/or sitting is desired.

Trundle

Thinner builds are necessary when considering a trundle mattress! If the mattress is too thick, it will cause issues when trying to slide it underneath the bed set it is attached to.

Kids Beds

Children’s mattresses are often thinner for two reasons.

Firstly, a smaller body and lower body weight require less support. Secondly, affordability, considering as the child grows they will likely need an upgrade.
