Best Customizable Mattresses

Learn about the top custom mattresses offered online, including custom size, custom firmness, and custom shape options.

By Natalie Yerger

A custom mattress refers to any mattress that’s customizable with regard to its size, firmness, fill, construction, or features. Custom mattress brands are becoming increasingly popular, and a growing number of third-party retailers are carrying them. The most common types of customizable mattresses are those that come in atypical shapes (like circles), custom sizes, and custom firmness settings.

Purchasing a bed that’s custom-made to suit your needs almost guarantees your satisfaction with the mattress for years to come, which is one of the most appealing aspects of a custom mattress. However, custom mattresses can be expensive, so it’s important to make sure the mattress you purchase is one you’re confidently investing in.

In this guide, we’re sharing the best customizable mattresses available online in 2021. Whether you’re looking for a special size mattress in the perfect fit for your master bedroom or an adjustable firmness mattress, this article should help. You’ll also learn about the types of custom mattresses available, important shopping considerations, and how to choose the best customizable mattress for your home.

Best Luxury Custom Mattress: Saatva Solaire

Saatva Solaire

Best Luxury Custom Mattress

An adjustable airbed (meaning it uses air pockets, rather than coils to support the sleeper) mattress from Saatva, the Solaire is our luxury pick with more than 50 air chamber firmness settings for truly customizable comfort.

The Saatva Solaire is an airbed mattress with 50 air chamber settings. The settings refer to the various firmness settings of the mattress, which can be easily adjusted by raising or lowering the air pressure with a remote control. In addition, the Queen and King size mattresses have dual-firmness. This means that the mattresses are constructed with two air chambers and two remote controls, allowing sleepers to select a different firmness setting than their partner’s.

If you’re looking for a mattress with a very wide range of firmness settings for various body weights and sleep positions, this is our recommendation. The Solaire is constructed with a cotton pillow top for added comfort, a comfort layer of gel-infused memory foam, and Talalay latex. The latex layer is zoned for ideal support along the spinal column and is followed by support layers of vulcanized air chambers.

The Solaire is our most costly custom mattress recommendation, but with its luxury construction, which features high-quality materials, thoughtful design, and unexpected features, we think this custom bed is worth the price tag.

Why Buy a Customizable Mattress?

Customizable mattresses provide a unique sleeping experience—one that can be modified on the fly in order to accommodate your individual needs. Let’s take a look at what specifically makes this customizability something worth considering.

Eliminate the Guesswork

With all the mattress options out there, there’s no doubt it can be stressful shopping for such an expensive item. After all, how do you know you’re getting the perfect mattress for you? With a customizable mattress, you don’t need to worry about what the right firmness option is or what sleeping positions will be supported. Instead, you can make adjustments to the mattress’ qualities in order to create your best possible sleeping experience.

Sleep Soundly with Your Partner

If you’ve ever shared a bed with someone, you probably know how frustrating it can be to find a mattress that suits both of your preferences. Maybe one of you likes to sleep all the way towards the perimeter of the bed, and so you need a high firmness level that provides great edge support, while the other one prefers a medium-firm mattress that cushions pressure points

Good news! Many customizable mattresses allow you to customize each side of the bed. Meaning you can build your side for pressure relief while your partner can make a nice, firm surface that provides great edge support and works well for stomach sleepers. As an added bonus, the separate sides can make for excellent isolation of motion transfer, meaning your restless partner won’t wake you as they toss and turn.

Sleep hot? Then you’ll love the variety of cooling options that some customizable mattresses offer. Materials like copper infused foam and cooling gel help keep hot sleepers from becoming uncomfortable as they sleep.

Choosing the Right Customizable Mattress


Because there’s no industry standard definition of ‘custom mattress,’ a variety of mattress types are often sold as custom or customizable mattresses. Below, we outline the types of mattress you may see online that are sold as custom beds or have customizable options.

  • Choose Your Firmness—Some mattress companies sell mattress styles that are available in multiple firmness options. For example, a hybrid mattress company may sell one mattress style that comes in soft, medium, and firm settings to suit a wide variety of sleepers. See: Best Firm Mattresses
  • Choose Your Height—Similarly, some mattress companies sell mattress styles in a variety of profile (height) levels. This allows sleepers to choose a bed height that they feel comfortable with or that suits their unique needs. For example, elderly individuals who have trouble getting in and out of bed may prefer a mattress with a lower profile.
  • Adjustable Firmness—Beds with adjustable firmness levels are mattresses whose firmness level and overall feel can be changed in a single model. Typically, these are air beds with remote controls to add or release air in the support layers. Flippable mattresses, split-firmness mattresses, waterbeds, air mattresses, and all-foam mattresses that can be unzipped and rearranged also fall into this category.
  • Adjustable Base—Mattresses that work with adjustable bases can be raised or lowered in the head, foot, and mid-section areas to accommodate for various injuries, sleeping positions, or in-bed activities, like reading and watching TV. Only some mattresses work with adjustable bases.
  • Custom Size—Custom size mattresses are mattresses that can be made in a variety of atypical shapes, like circles and ovals, or have custom dimensions that don’t fall into the standard mattress size (twin mattress, full mattress, etc.) dimension categories. Most often, custom size mattresses are used as boat mattresses, RV mattresses, or camper mattresses, but some sleepers have unique bed frames or sleeping spaces at home that require custom mattress dimensions.


Below, we share important buying considerations to keep in mind prior to deciding on a custom size mattress, custom firmness mattress, or other type of custom bed.

  • Type—Whether you want an all-foam, latex, innerspring, hybrid mattress, or another style, custom mattresses are available in any mattress type. We recommend choosing the type of mattress you want prior to settling on just any custom bed, as the type will have the most impact on the mattress’ overall feel, price, features, and longevity.
  • Durability—Some custom beds, especially custom-shaped beds, tend to be more expensive than others. The mattress’ durability, or how long it will last, is an important factor to consider when purchasing an expensive mattress that may not fit into a new space if you move or purchase a different bed frame.
  • Firmness—Whether you’re looking into custom profile beds, custom size mattresses, or beds with dual-firmness settings, it’s a good idea to know the firmness that best suits your sleeping style and personal preferences prior to shopping. Take a look at our Mattress Firmness Guide if you’re not sure.
  • Price—Custom beds are more expensive than standard size models because they’re specially-made, requiring more time and sometimes materials on the part of the manufacturer. It can be easy to get carried away when you see beautiful beds with unique features and setting options, so we recommend setting a budget prior to shopping and doing your best to stick to it. 
  • Policies—It’s fairly standard for online mattress companies to include free delivery, generous warranties, and long trial periods with any new mattress purchase. This should be especially true for custom beds that incorporate various profile heights and firmness levels, and it should absolutely be true if you’re paying to have a new mattress custom-made from scratch. 
  • Brand/Retailer Reputation—There’s no doubt that the reputation of the company or retailer is important for any purchase, but we think it’s especially important when purchasing a custom mattress. Mattresses are among the more expensive items purchased for any home or sleeping area, and the brand or retailer’s reputation with regard to quality, customer service, durability, and more will improve the chances that you’ll enjoy the mattress you invest in. We recommend reading our reviews and browsing customer testimonials prior to purchase.

Picking the Right Mattress for You

There’s no right or wrong with regard to choosing a custom mattress. As mentioned, ‘custom mattress’ means different things to different shoppers. For some, it’s a true custom-made mattress with a unique shape, size, firmness setting, and set of features that costs a pretty penny. Other sleepers simply want the option to choose the firmness setting of a budget-friendly mattress that they’ll use for a few years.

Before shopping, evaluate what you’re looking for in a custom mattress, the type of mattress you want, and what your budget is. From there, we recommend reviewing our list of the top custom mattresses to see if there’s one that fits your set of criteria.


If you’re ready to get rid of an old, antique bed, a custom mattress is a good way to go. At the end of the day, the custom new mattress you purchase should feel like a worthwhile investment, and you should be happy with any custom mattress you buy. After all, it is custom made for you. 

For any custom mattress purchase that isn’t standard size (a true custom-made bed), we recommend closely reviewing the manufacturer’s return and warranty policy to make sure you’re protected in case the mattress isn’t up to your expectations or doesn’t meet the specifications you designated. Most likely, you won’t be able to try out your custom mattress in a mattress store showroom, so it’s a good idea to be sure before you buy.
