Our Take

Once this California King mattress arrives, all you need to do is unbox it and roll it out across your bed frame. The mattress will plump right up all by itself. It's constructed from a soft foam using an open-cell design that adjust to your body, even if you move around during the night.

What other experts liked

I think this bed could be fantastic for back sleepers! It’s highly supportive, ensuring neutral spine alignment from the shoulders all the way to the lower back.
- Sleepopolis
We recommend the Tuft & Needle Original Mattress for all sleep positions, but particularly for people who rotate frequently in the night.
- New York Times Wirecutter
It’s accommodating, comfortable, and actually kind of bland, but in a good way. It’s one of those beds that basically anyone can get comfortable on because it’s so neutral.
- Slumber Yard
When it comes to bed-in-a-box foam mattresses, the Tuft and Needle is one of the most fantastic deals; it features a streamlined, soft, all-foam design with no particular frills.
- Mattress Clarity

What other experts didn't like

That being said, heavier folks may find that the bed isn’t quite supportive enough for their specific needs. With a simple two-layer design, it’s not really built for folks over 250 lbs.
- Sleepopolis
As with other mattresses that cost less than $1,000, we don’t think the Original will prove durable enough for people who weigh over 200 pounds.
- New York Times Wirecutter
If you’re over 250 lb, we just do not believe it will have the long term support that you require.
- Slumber Yard
For those who sleep primarily on their stomachs, the Tuft and Needle mattress might not be suitably supportive; stomach sleepers may want to look for a significantly firmer mattress to ensure their hips don’t sink in quite so far.
- Mattress Clarity

Thanks to the quilted polyester tight-top surface and individually wrapped pocket coils, any motion or bouncing is absorbed, which is particularly great for partners with different sleep habits or schedules.

Our California King Mattress Buying Guide

King beds are great for those who like to spread out a little, but it’s only wider than a queen bed, not longer. If you’re more than a few inches over six-feet tall, you probably have noticed this similarity. That’s where a California king mattress comes in.

Surprisingly, a California king isn’t as wide as a standard King bed, although you may not notice the few inches you’re giving up. With California kings, it’s all about that extra four inches in length you get. A standard king mattress is 76-inches by 80-inches, while a California king will give you 72-inch by 84-inches. Not a huge difference, but when your feet reach all the way to the end of a standard mattress, it’s a welcome expansion. But if width matters, you’re better off with a standard king.

The addition of California king to the roster isn’t the only thing complicating mattress choices these days. At one time, mattresses were made up of coils and cushioning, later on adding a “pillow top” for extra softness. But innovators have brought us technologies like memory foam and gel that can enhance comfort without sacrificing support.

There are multiple types of mattress construction today. One is an innerspring mattress, which is the version people have slept on for decades. With an innerspring, you get a grid of coils that provide support and bounce, along with padding to keep you from sleeping on springs.

But today, you’ll often see what’s known as a hybrid mattress. These mattresses individually pocket each spring to support you while also keeping bounce at a minimum. This means if you’re sleeping with someone and that person rolls over, you won’t feel it as much as you would on a traditional mattress setup.

Then there are all-foam mattresses, which typically combine layers of foam to create a comfortable yet supportive sleeping surface. It’s important, with foam mattresses, to look at the number of layers, as well as whether they use memory foam, latex foam or another type, as each kind of foam provides a different type of experience. You’ll also find that some foam mattresses use gel in one form or another to keep you cool while you sleep.

DWYM Fun Fact

Your brain isn’t the only thing that restores itself during a good night’s sleep. Your body also rids itself of dead skin cells, and those cells end up in your pillow, bedding and mattress. To help with this, you should wash your bedding in hot water at least once a week, including your pillowcases. During sleep, other body processes are halted, including the production of urine, which is why you might notice a darker color in the bowl during that first trip to the bathroom each morning. During REM sleep, your body also enters a state of paralysis to prevent moving around while you’re dreaming.

The California King Mattress Tips and Advice

  • Before you start shopping for a mattress, think about what you need. If you have a bad back or other aches and pains, you’ll need support. A mattress that causes you to sink into the bed may only exacerbate your issues.
  • You should also consider how you sleep. If you spend most of the night on your side, for instance, a mattress that conforms to your shape like one made from soft foam could work better for you. Stomach sleepers, on the other hand, will find a firmer mattress less suffocating.
  • You’ll see bounce mentioned quite often with mattresses. There are pros and cons to having that extra bounce. A mattress with less spring can make you feel as though your movements are limited. However, if you sleep with someone else, that bounciness can become a nuisance, with the bed shaking every time the other person moves.
  • Foam offers more cushioning than springs with padding, but it comes with a downside. Foam can tend to increase your body heat, making you uncomfortable while you sleep. For that reason, many manufacturers use gel to cool things off.
  • If you’re ordering your mattress online, keep in mind that some mattresses need time to unpack. Those that come in a box have to be removed and left to gradually decompress over the hours, and sometimes days, that follows.
  • Online mattresses also may release some chemicals after being unpacked. This is known as off-gassing and is common in manufactured products like memory foam. Some people find the chemical smell while this is happening unpleasant, so you may want to unpack your mattress in a well-ventilated room. Open some windows when you can and allow a couple of days before setting your mattress up and covering it with bedding.
  • Keep in mind that different mattresses have varying thicknesses. If you’re buying a California king bed for the first time, you’ll probably need to purchase sheets to accommodate the new length, but also keep in mind that your fitted sheets will need to be made to fit the thickness of the mattress you choose.
  • Also keep in mind that other items you currently use, like blankets, duvets and comforters, might not accommodate the longer build of a California king bed and replace those if necessary.
  • Although California king mattresses can be pricey, you can find lower-priced online mattresses if you aren’t picky about comfort levels. If you’re buying a mattress for a dorm room or first apartment, this is a great way to save money.
  • Durability is important in a mattress, but keep in mind that for optimum comfort, experts recommend replacing your mattress every 10 years.
  • Some mattresses have covers you can remove and wash. If yours doesn’t come with one, you can separately purchase a mattress cover that will help you maintain a hygienic environment.
  • You probably won’t have to move your mattress very often but consider how difficult your mattress will be to maneuver if you rearrange your furnishings or relocate on a fairly frequent basis.
  • Some mattresses specialize in emitting a subtle scent, such as green tea. If you prefer to fill your home with pleasant smells, this may be a good option for you.
