If standard sized mattresses leave you feeling cramped, you might enjoy the possibilities offered by oversized mattresses. With plenty of room for children, pets, or just lounging in comfort, it’s no surprise that oversized mattresses have become a must-have for so many people.
Yet choosing and purchasing an oversized mattress can be overwhelming, since customers have to consider both the usual questions when buying a mattress and additional considerations unique to extra-large beds. Choosing a size — and understanding the difference between a Texas king and a Wyoming king — is only the first step. Non-standard bed sizes are reasonably easy to find for sale online, but choosing a mattress manufacturer can also become a headache.
To help our readers choose the right oversized mattress for their needs we’ve tested a number of brands and chosen our two favorites. We’ve also detailed important considerations for the buying process which will walk you through everything you need to know. Buying an oversized mattress should be exciting, not overwhelming, and having the right information will make the process as stress-free as possible.

Ace Size is a high-quality manufacturer of sturdy, well-constructed oversized mattresses and accessories. With a plethora of mattress options and the ability to bundle your mattress with bedding, a base, and a headboard, Ace Size makes it extra easy to buy an extra-large bed.
The Ace Size collection includes three sizes: Ace size (80 inches x 108 inches), Ace Player size (108 inches x 80 inches), and the Ace Family size (80 inches x 144 inches). Each is available in two firmness options — medium soft and medium firm — that should satisfy the majority of sleepers. The standard mattresses have a hybrid design with both pocketed coils and a 2-inch comfort layer of polyfoam that contours gently for balanced pressure relief.
However, each of the Ace Size mattresses is also available in three variations. The first option features a gel foam pillow-top, which increases the mattress’ pressure-relieving qualities without affecting its temperature regulation. Next, the all-natural mattress replaces the standard option’s bamboo-derived cover with organic cotton, and its polyfoam comfort layer with both 100% natural Talalay latex and a topper made of organic cotton and New Zealand wool. Finally, the cotton option offers a latex-and-cotton comfort system, in addition to extra steel reinforcement and high-density foam perimeter support.
When purchasing an Ace Size mattress, you can create a bundle that includes a base, headboard, and bedding set. Given that the company uses custom sizes, this is your best option if you choose to purchase from them. However, prospective customers should keep in mind that Ace Size does not offer a sleep trial, a common downside of purchasing an oversized mattress. Returns are accepted within 5 days of delivery, minus a handling fee. The company offers a 10-year limited warranty on their mattresses and bases.

Natural Form is a Vermont-based company with 25 years of mattress manufacturing experience. Their custom oversized mattresses are made with care and attention to detail, from the balanced pressure-relieving design to their unique modular construction that allows their beds to fit through even cramped doors and hallways.
Standard oversized sizing makes it easier to shop for accessories like bed frames and bedding. Natural Form’s mattresses are available in Wyoming king (84 inches x 84 inches), Texas king (98 inches x 80 inches), Vermont king (96 inches x 96 inches), and Alaskan king (108 inches x 108 inches)..
Each mattress is custom-made, allowing customers options in their firmness preference, but all of Natural Form’s oversized mattresses have a hybrid design featuring pocketed steel coils, a pressure-relieving foam comfort layer, and a breathable cotton cover. Our testers were particularly impressed by the balanced support through the pelvis, allowing the mattress to offer excellent support and comfort for a surprisingly wide range of sleepers.
Oversized mattresses can be difficult to fit into rooms, and Natural Form has addressed this concern by giving their beds a patented reinforced cut that allows them to fold. This makes it significantly easier to move the mattresses, as they are able to fit through doorways and other tight spaces that a traditional oversized mattress may not be able to squeeze through.
Due to their custom construction, Natural Form’s mattresses do not have a set price and interested customers must submit their details for a pricing quote. Although they offer a sleep trial for their standard mattresses, this does not apply to their custom-made models. However, the company does have a 10-year limited warranty and offers free shipping for many customers.
People choose an oversized mattress for all kinds of reasons, but the most common are needing more space for more sleepers — such as co-sleeping with children, or with pets — or simply wanting a massive bed to stretch out in. Different reasons for buying one require different considerations to ensure you make the right choice, so it’s crucial to know what your needs are before making a purchase. Oversized mattresses also have certain drawbacks, like being very difficult to move, which you should know before bringing one home.
Choosing an oversized mattress is similar to buying a standard sized bed, but there are also specific considerations to keep in mind. For example, excellent motion isolation is important for anyone sharing their bed, but sharing your bed with multiple people or animals makes it even more indispensable. In this guide, we’ll walk you through everything you should think about before purchasing your oversized bed.
No single mattress is perfect for every sleeper, and this remains true for oversized mattresses. Mattress suitability is based on a range of factors such as your weight, budget, and sleep position preferences. Personal preferences also play a large role in choosing a mattress, with some people enjoying — for example — the close contouring of memory foam or the bouncy responsiveness of latex. Some categories below may be more or less important to you, but by considering each of them carefully you’ll be far more likely to choose the right mattress for your needs.
Oversized mattresses are more expensive than standard sizes due to two factors: the amount of material used in construction, and the relative lack of demand. Mattresses above California king tend to start at $1500 for the very lowest end models, but prices can be well above $10,000 for top-of-the-line luxury models or very large sizes.
Your preferred positions for sleeping make a massive impact on whether a mattress will be right for you. In general, side sleepers require above-average pressure relief, back sleepers tend to need excellent support, and stomach sleepers need a combination of pelvic support with pressure relief. Depending on how many people share a bed, finding a bed that works for everyone can be difficult.
We all want to have a mattress that is well-constructed and made of high-quality materials, but the additional cost of an oversized bed — as well as the increased load it may carry — makes this factor even more important. We encourage our readers to buy the best mattress available within their budget, rather than choosing a less durable model.
Firmness preferences tend to correspond with weight, as sleepers above 230 pounds tend to prefer much firmer mattresses than those below 130 pounds. Firmness is both a support and comfort issue for people in higher weight brackets, rather than purely a comfort issue, so families should find a middle ground that leans towards the needs of adults rather than growing children.
Oversized mattresses are larger than the standard bed sizes, but bigger isn’t always better. Make sure to decide on a size that fits your needs, within your budget, and in your room.
Pressure relief is crucial to prevent next-day aches and pains, and is particularly important for side sleepers who can experience pressure points at their hip and shoulder. Memory foam is well-known as the most pressure-relieving material, but nearly all mattresses are designed with some amount of relief in mind. Many people mistake firmness for pressure relief, but even a very firm bed can have excellent performance in this category.
Customers planning to sleep many people in one bed should carefully consider a mattress’ motion isolation, particularly if they will be sharing with restless children or pets. Good motion isolation ensures you won’t be disturbed when your sleep partners roll over, change positions, or get out of bed.
This category is a matter of both comfort and sleep quality, since a bed that sleeps warm can make it very difficult to fall or stay asleep. Additional people can also raise the bed temperature, particularly if you’re sharing bedding, so keep that in mind when deciding on a mattress.
A mattress with excellent edge support allows people to sleep close to the perimeter without feeling any loss of support, as well as allowing them to sit on the edge without the bed flexing or bowing. A high-quality oversized mattress should perform well in this category to ensure stability, durability, and support.
Mattresses that contour closely to the body are often highly pressure-relieving, creating the feeling of sleeping “in” rather than “on” your bed. However, low-contouring mattresses tend to be more responsive and temperature neutral. Choosing between the two is largely a matter of personal preference.
Oversized mattresses are available in the full range of mattress types, including all-foam, innerspring, hybrid, latex, and more. However, the most common types tend to be innerspring and hybrid mattresses. Each mattress type has its own benefits and drawbacks, as well as a higher or lower price range, but none is universally better than the others.
There is a wide range of oversized mattresses available, so every customer should be able to find one to fit their budget and needs. While Wyoming, Texas, and Alaskan king sizes tend to be the most popular and easiest to find, some manufacturers also make even larger or irregular sizes.
The Wyoming and Texas king sizes are longer and wider than your average king or California king bed, while the Alaskan king is significantly larger in both dimensions. Many customers choose the latter two for extra room to move, and the Alaskan king for co-sleeping with children or pets, but all can work for a wide range of purposes. There are also even larger sizes available, two of the most common being “family” or “family XL”, though these are rarer and more difficult to find accessories for.
|Wyoming King||Texas King||Alaskan King|
|Dimensions||84″ x 84″||80″ x 98″||108″ x 108″|
Mattresses can be constructed in many different ways, ranging from the traditional innerspring to newer designs like all-foam, hybrid, latex, and more. Each type of mattress has characteristic pros and cons, as well as average price ranges, but there is a significant variation among different mattresses within each category. Oversized mattresses are available in all the common mattress types, but the most common tend to be innerspring and hybrid models.
Definition: Innerspring mattresses use a traditional support core of interlocking steel coils with a thin comfort layer that is usually polyfoam. They tend to be among the most inexpensive and responsive options, though with less motion isolation and pressure relief than hybrid mattresses.
Highlight: Although most innerspring mattresses have slightly below-average pressure relief, their lower price-point allows you to use some of the money you saved to buy a pressure-relieving mattress topper. Toppers can be particularly useful when different family members have different preferences, as you can choose to cover half the bed for a mix-and-match feel.
Definition: A more modern bed type, hybrid mattresses combine synthetic or natural latex foam comfort layers with a pocketed coil support core. Since pocketed coils are individually encased in fabric, they offer better pressure relief and motion isolation than the linked coils of an innerspring mattress.
Highlight: If your budget can accommodate the higher price of a hybrid mattress, they offer the best features of different mattress types in one package. Well-made hybrid mattresses tend to have some of the highest scores across a wide range of factors, making them a comfortable, supportive, and durable choice.
As mentioned, oversized mattresses are available in less common constructions such as all-foam and latex. However, these tend to be harder to find and more expensive than even hybrid models due to the lower demand. Given that it is possible to recreate the feel of other types with the right hybrid mattress or by using mattress toppers, customers should consider their needs carefully before purchasing a different style.
Oversized mattresses may be rarer than their standard-sized counterparts, but that doesn’t mean purchasing one needs to be confusing. All the same, there are still important considerations to keep in mind before bringing home your new bed.
The general rule of thumb is that a 12 foot 10 foot room can comfortably accommodate a king-size bed. For every 10 inches wider your bed is than a 76 inches-wide king size, your room should be at least a foot wider. Oversized beds can also be squeezed into smaller rooms, but this can make your bedroom feel very cramped and reduce storage or living space.
Oversized mattresses vary widely in price depending on size, style, and features, starting around $1500-$2000 for budget models and soaring past $10,000 for the most luxurious. In addition to the price of the mattress, you must also consider the cost of your bed frame and bedding.
Many oversized mattress manufacturers offer accessories — such as bed frames and bedding — as part of a bundle when purchasing your mattress, as well as separately. Taking advantage of a bundle can save you money, as buying these items separately can be expensive. Options for oversized mattress accessories also tend to be limited. However, many people choose to buy several top sheets and comforters to cover their bed, rather than bedding large enough to cover the whole mattress, which allows for more freedom.
Oversized mattresses can be more difficult to care for due to their weight and size. For example, flipping or rotating a family XL-size mattress is significantly more of an undertaking than flipping a queen mattress! However, most need similar care and can be cleaned in similar ways to any other bed. The one difference tends to be the support they require, which must be comparatively stronger than that of a smaller bed.
