Is the Pillow Cube good for side sleepers — or just another money-sucking trend?

Everyone wants a better night’s sleep; there’s no doubt about it. The latest sleep trend is designed specifically for side sleepers: a pillow shaped like a cube, which claims to be just right for those who most often sleep on their sides. But is the aptly-named Pillow Cube worth the splurge or is it just another gimmick?

What’s a Pillow Cube, anyway?

The Pillow Cube is thicker than more conventional pillows and is designed to help side sleepers keep their heads from slanting down and waking up with a crick in their necks. With that said, the way it’s made could allow other people who might need to have their heads propped up, such as snorers or the elderly, to increase their airflow and thus breathe better.

The Pillow Cube Pro is slightly larger than the classic version and measures 24 by 12 inches. Additionally, instead of being square, it’s rectangular and comes in three heights instead of two. (4, 5, and 6 inches).

What’s the difference?

The most significant distinction that sets the Pillow Cube apart from others is that the manufacturers designed it only for side sleepers. In contrast, most conventional pillows are for anyone and everyone.

For example, typical pillows on the market include:

  • Standard pillows, the most common out of all the pillows on this list. This is what you probably think of when you think of pillows. They fit all bed sizes and typically measure 20 by 26 inches. They fit in both standard and queen-sized pillowcases.
  • Super standard pillows measure 20 by 28 inches and thus are a bit longer than the standard. These types of pillows also fit within both standard and queen-sized pillowcases and are usually purchased by people who need more help in keeping their heads level throughout the night.
  • Body pillows measure 20 by 54 inches long, and many people use these pillows to provide support and act as pressure-point relief. Part of that is helping individuals maintain a better sleep position all night long.

As you can see, none of the common pillows on the market today are designed specifically with the side sleeper in mind, as the Cube Pillow is. In addition, the material that fills most pillows is made up of micro-feathers, down, kapok, micro-beads, buckwheat, gel, latex, wool, innersprings, or even water. In contrast, the Cube Pillow is one of the only square pillow brands made up of high-rebound foam, a firm type of foam that usually forms the bottom layer of memory foam mattresses.

Final thoughts

If you’re a side sleeper, you might want to try out the Pillow Cube. It’s supposed to help with spinal alignment and improve airflow. It claims to provide sleepers with maintaining a perfect angle between the head and shoulders and keeps you comfortable for a restful eight hours of sleep.

There are mixed reviews online, with some suggesting it works better than anything they’ve ever tried before. Others, however, can’t seem to figure out what the fuss is about. The 50 reviews on Pillow Cube’s website mostly rave about the pillow, claiming it’s responsible for their “best sleep ever.” However, other reviewers like Wirecutter and New York Magazine were less impressed, noting that the pillow is uncomfortable for people who tend to move around at night and didn’t provide the sleep catharsis the website promised. At the end of the day, whether it will help you get better sleep may simply be a matter of opinion.

French country decor that will wow any room
French country is making a comeback. Here's how to make it work for you
Interior country-style kitchen

French country design is one of those classic styles that never goes out of trend. It has so much history and stories behind it, and it stays in favor because it's stylish, comfortable, and also uber luxurious. There's a reason we see French country design in so many high-end hotels and restaurants all over the world! There are so many ways to bring French country decor into 2023 without it feeling too "shabby chic," which has fallen out of favor in recent years. Here's how you can make this style work for you.

Muted tones
French country uses gorgeous fabrics with provincial designs, and those can be achieved in furniture fabrics, curtains, and even on the walls. Muted tones like beige, gray, blue, and sage green can be added to wallpaper, pillows, and when selecting chair fabric. When thinking about the walls, choose softer tones in ivory, beige, or pale yellow to complement the muted tones in the rest of the space. Another option for wallpaper or pillows is toile — a staple in French country design.
Distressed, painted furnishings
Another trademark of the French country style comes with distressing. You can accomplish this with a large distressed couch bought at a vintage store or one made to look vintage (which is a more cost-effective option). Larger pieces of furniture offer a dramatic effect in a living room or kitchen. We love this ivory nailhead chesterfield design from Overstock. If you're not entirely sold on a large piece to invest in, consider decor like lamps, trays, or a small table. Then, once you commit, you can add larger pieces to the room.
Wrought iron
Wrought iron is another trademark of French decor, and there are plenty of options to introduce them into a room. You can find kitchen chairs, bar stools, cabinets, coffee tables, and headboards. You can keep the color in its natural state or paint it with gold or darker colors. In traditional French country, the wrought iron would be curved or designed in an interesting way rather than straight lines more common in industrial design. An ideal use of wrought iron would be with kitchen chairs, where a layer of muted, soft fabric can be added for dramatic effect. You can complement this with soft wood cabinets, wood beams, and muted granite countertops in light ivory.
