Who should buy the Big Mattress Co Big Mattress Premier
- All sleeper types
- Couples with 2 small children
- Hot sleepers
- Heavier individuals
Firmness
Coming in at a 5.5 on the mattress firmness scale, the Big Mattress Premier has a medium feel. This makes it suitable for all sleeper types, including side sleepers and combination sleepers. We do suggest that heavier individuals who are strict back and stomach sleepers – specifically adults weighing 230 lbs. and up – should opt for the hybrid version as the Big Mattress Premier Hybrid’s firmness levels can be adjusted all the way to an extra firm due to it containing air pods rather than the usual spring coils .
Both the hybrid version and all-foam version offered good motion isolation, perfect for sharing a bed with a partner and of course, your kids. We did find that the hybrid version was ever so slightly springier.
Construction
The Premier foam version of the Big Mattress Premier is made up of 13 inches of Big Mattress Co’s plush contouring foam, which is their own memory foam alternative. Soft and contouring, just like memory foam, it is a little bit more responsive though and we did not feel as though we were being swallowed up by the bed. Because of its contouring feel, it is a great choice for strict side sleepers as well as those who suffer from chronic pain like fibromyalgia.
The Hybrid version of the Big Mattress Premier comes with a mix of premier foam and up to 80 pieces of Big Mattress Co’s patented air pods. Inherently more responsive than the all-foam version, the Big Mattress Premier Hybrid allows you to manually control the air within the air pods which then either softens or firms up the firmness level of the mattress. This is a good option for those who want a bit more control and customization when it comes to firmness levels.
Both the all-foam and hybrid versions of the Big Mattress Premier come encased in a soft, breathable cotton fabric that also offers temperature regulation. This means you stay warm when it’s cool and you stay cool when it’s hot.
The foam used in both versions of the Big Mattress Premier are CertiPUR-US certified as well as OKEO-TEX certified. This means that they are free from any harmful toxins or chemicals that may be harmful to your health or the environment.
The Big Mattress Premier comes with replaceable components so should any normal wear and tear happen, the Big Mattress Co. would be happy to replace them, with a minimal fee.
Sizes
The Big Mattress Premier comes in all oversized mattress sizes, including a Family Bed. It measures 13 inches in thickness.

The Big Mattress Premier comes with a risk-free 100 night sleep trial and comes backed by a 10 year warranty. Shipping is free within the continental United States but because the Big Mattress Premier is made to order, it may take a couple of weeks to be ready.

#2. Mattress Insider The Family Bed
Check Current Price | Best for Large Families
Pros
- Suitable for larger families
- Comes in a range of family bed sizes
- Cooling
Cons
- No sleep trial
- No returns
The Mattress Insider The Family Bed comes in 3 different family bed sizes, giving you the option to choose a family bed that can accommodate your whole family. What’s more is that they also give you the option to change the height and firmness of your bed, just by adding or taking away a layer or two. Customization is key, especially when it comes to a family with different firmness preferences and varied sleeping positions.
Who should buy the Mattress Insider The Family Bed
- Large families
- All sleeper types
- Those who prefer customizing their beds
- Heavier individuals
Firmness
Because the firmness level of the Mattress Insider Family bed can be customized, we found that it can range from a medium to firm feel. This makes it a good option for all sleeper types, including strict back sleepers.
Changing the firmness level is pretty easy with the Mattress Insider Family bed – you simply take away some layers to make it feel softer, or add some more to make it feel firmer. It comes shipped with the full range of layers and you just add or take away as you please.
Being a hybrid mattress, we found that it is suitable for those who weigh well over 250 lbs. and we also found that it gave very minimal motion transfer, which is crucial when sharing a bed, especially with multiple people.
Construction
The Mattress Insider Family Bed is made up of a blend of different types of foam, along with a pocketed coil support layer. This makes for an ultra-responsive bed that’s also contouring.
The top comfort layer is made up of supportive memory foams, allowing for that cuddled-in feel that offers optimum pressure relief. The Mattress Insider memory foam includes cooling gels that help wick away heat away from the body as well as the mattress.
Below that lies a transition layer of Talalay Latex foam. Responsive and naturally hypoallergenic, latex foam offers an extra layer of support that does not let you sink into the bed.
The support layer is made up of individually wrapped coils that help with spinal alignment. Pocketed coils also offer good motion isolation.
The base layer is made up of high density polyfoam that helps keep all the layers intact while providing a sturdy base for the entire mattress.
All these layers come encased in a soft, organic cotton quilt that adds an almost pillowtop-like feel to the mattress.
Sizes
The Mattress Insider Family Bed comes in all oversize mattress sizes, including a Family Bed XL. It measures 13.5 inches in thickness.

#3. Big Mattress Classic
Check Current Price | Best for All Sleeper Types
Pros
- Suitable for heavier individuals
- Contouring and pressure-relieving
- Cooling
Cons
- Can only take custom-made sheets
- Stuck in the mud feel
The Big Mattress Classic is the Big Mattress Co’s flagship oversized mattress. Made with their original classic memory foam alternative, it is a good option for those wanting a true memory foam feel. For those wanting a more responsive mattress, they also offer a hybrid version.
Who should buy the Big Mattress Classic
- Those who want a true memory foam feel
- Those who share a bed with family and pets
- Hot sleepers
Firmness
The all-foam version of the Big Mattress Classic comes at a 6 on the mattress firmness scale, making it a medium firm. This makes it suitable for most sleeper types, except for lightweight side sleepers who might find it to be a bit too firm.
The hybrid version’s firmness levels can be adjusted via its air pods and we found it to be around a 5-7 on the mattress firmness scale. This makes it suitable for all sleeper types, including stomach sleepers.
Both versions offered good motion isolation – important for when you share your bed with your family as well as a pet. We always recommend heavier individuals to opt for the hybrid version for added support.
Construction
Just like the Big Mattress Premier, the all-foam version of the Big Mattress Classic comes in one slab of their very own memory foam alternative. In the case of the Classic, it comes with the classic foam, which offers a more traditional memory foam feel. We found it to be a good match for those who need extra pressure relief and for those who do not mind a more cuddled-in feel.
The hybrid version of the Big Mattress Classic comes with a blend of classic foam but with the added responsive feel of up to 80 air pods in lieu of the more common spring coil system. These air pods offer responsive support that almost feels like a zero gravity bed, which we found to be great for proper spinal alignment.
Both the hybrid and all-foam versions of the Big Mattress Classic comes encased in a soft, breathable cotton cover that’s temperature regulating, which is a good option if you live in a place with both hot and cold seasons.
All the foams used in both versions are CertiPUR-US certified as well as OKEO-TEX certified. It is be a good option for those who suffer from seasonal allergies or are pretty sensitive to any chemical additives. Like its Premier counterpart, the Big Mattress Classic comes with replaceable components that is both economical and sustainable.

What is a Family Bed?
A family bed is a bed that can fit and accommodate the entire family. The term family bed is also used to represent the practice of both parents, their children and even a pet or two sharing the same sleeping space.
Co-sleeping has long been practiced throughout the world since the beginning of civilization. In fact, it has only been in the last 100 years that families have practiced separate sleeping arrangements. To this day, families from different cultures around the world still share the same bed or bedroom.
Studies have shown (and numerous studies are still being conducted) the benefits of sharing a bed with family, especially with a baby or a child. The main one being the creation of a lifelong bond between parent and child.
New parents, in particular, share the duties of caring for a newborn baby and these duties may result in poor, broken sleep caused by getting up often to attend to the needs of the baby who is sleeping in a cot in another room. Sharing a bed with babies means parents are in closer proximity to the child and are able to immediately attend to their needs. This also means that as their child begins to doze off, they also could – all while keeping close watch.
Children – especially ones suffering from anxiety – sharing a bed with their parents often alleviates the root causes of fear and anxiousness. Sharing a sleeping space with the entire family creates a safe environment which is conducive to a great night’s sleep.
Things to consider when buying a Family-size mattress
Family beds do not come under standard mattress sizes. Often, these oversized beds are made to order upon purchase. These days, online retailers and select mattress brands ready-made family beds aside from the more common King sizes such as the Alaskan King bed and the Wyoming King bed.
But, just because a mattress is large must not be your only criterion for choosing an oversized mattress. Just like buying a regular-size mattress, there are a few key things you must consider:
- How many of you will be sleeping on it – The number of people who would be sleeping on the bed dictates how big the family bed should be. This also means taking enough space to move around into consideration. You wouldn’t want to be sleeping packed like sardines, do you?
- Mattress type – Both you and your partner should be in agreement whether you would prefer an all-foam mattress, an innerspring or a hybrid mattress. There are different benefits to the various mattress types. As an example, regular memory foam can be heat-retentive and if the majority of your family are hot sleepers, you might want to choose a mattress type that helps regulate body temperature. You want maximum comfort for the entire family and not just for one.
- Room size – Although it might be be a little counter-intuitive to say since you are here because you are on the hunt for a family bed and it would be safe to assume you have a bigger bedroom but you should take your bedroom size into consideration. Will it fit the bed you want? Will you still have space?
Oversized mattress alternatives
Other oversized mattresses can be used as a family bed as long as it can fit you and your family with a little bit of room to spare. The Family Bed XL is the largest mattress size, but there are other options.
A few examples are:
- Alaskan King bed – An as Alaskan King bed measures 108″x 108″ and can fit 2 adults and 2 small children comfortably.
- Wyoming King bed – A Wyoming King bed measures 84″x 84″ and can fit 2 adults and a small child.
- Texas King bed – A Texas King is narrower but is quite tall. It measures 80″x 98″ and can fit 2 slim adults and 1 small child.
- Vermont King bed – A Vermont King bed is not as common as the other three oversized beds previously mentioned but some mattress brands do offer them. It measures 96″x 96″ and can fit 2 adults and 2 small children.

Co-sleeping has been found to strengthen the bond between family members while provided a safe and more nurturing sleeping environment.
