OSO mattress review
Sleep your way to beauty and health

An OSO Mattress was provided by the company for the purpose of a review. All opinions are my own. Some GGS articles include affiliate links. 

I was always the kind of person who could sleep anywhere. On the floor? Check. On a plane? Check. In a car? Check. On the cold, hard ground while camping? Check.

Then everything changed.

I tweaked my back when I was in college, and while it didn’t cause major problems initially, over time, with high-stress jobs, less time for exercise (most notably, stretching) and a bout of depression, an occasional “off day” turned into a nagging, daily pain through my low back and hips. Sleeping, especially given my propensity to sleep on my stomach in a bed shared with my husband and three large dogs, became a form of nightly torture.

They’re convinced the bed is theirs.

I tried everything. A new memory foam mattress, a giant body pillow, pain medications, an acupressure mat, a daily yoga practice, chiropractic care, foam rolling, you get the picture. All of my attempts were somewhat helpful, but none of them left me feeling fresh, rejuvenated and pain-free in the morning.

And it’s not just my sleep that suffered. Every morning I’d wake up feeling tired.  My skin and hair would look dull, my eyes baggy and red. While I realize I’m approaching my mid-30s, I don’t want to feel like I look 45 every morning.

Something had to give. I needed a solution for a better night’s sleep. Not just so I could wake up pain-free, but so I could feel like I looked my age again.

That’s when I was approached by OSO Mattress.

The OSO Mattress difference

OSO is a high-quality, bed-in-a-box mattress system that’s different from other, similar systems on the market, such as Casper and Leesa. I know this is true because about two years ago, my husband and I bought a Casper mattress in the hopes that it would help both of us sleep better. He loved it, I hated it. I still hate it. The Casper mattress is fundamentally too firm for my body and actually makes my back hurt more.

What’s different about OSO is that it offers a customizable feature other systems don’t have. Namely, by rotating your mattress 180 degrees (or if you don’t have a headboard, just rotating yourself 180 degrees), you can switch from a firmer mattress to a softer mattress, or vice versa. Heck, if you like a softer mattress and your partner likes a firmer one, you can both get what you want by sleeping head-to-foot. (OK, so that may not be ideal, but you get the picture).

What stood out to me about sleeping on the mattress, though, wasn’t just the fact that I could choose between a softer and firmer sleep experience, but that I’d been subjecting my body to firm mattresses for years, when what I really needed was a “cushier” place to sleep. Firm mattresses, like the Casper, were contributing to my back pain. The OSO mattress actually helped keep my pain at bay.

The best part of OSO: The foam springs

The OSO mattress itself is nine inches deep, with the top 1-1/2 inches featuring a hypoallergenic latex layer, the next 1-1/2 inches a foam “float” layer, followed by what I think is the best part of the mattress – the Dreamcell foam springs surrounded by a six-inch support layer of foam.

It’s these Dreamcell foam springs that come in different firmnesses that are laid out within the mattress to provide you with a softer or firmer experience. And while it’s almost impossible to know for sure, I think it’s also these springs that have helped my back. Keep in mind, OSO’s springs aren’t the metal spirals you typically think of when you hear “mattress springs;” rather, they’re small, foam cylinders that are laid out, one next to the other, so each one can “give” independently. They also come in different densities, so when soft are next to soft, like on one side of the mattress, the sleep experience is softer.

This is unique, especially for a bed-in-a-box mattress system.

Compare it, for instance, to the Casper mattress which has multiple layers of latex and foam, ultimately culminated with a thick bottom layer of “Durable Support Foam.” To me, this support foam feels like sleeping on a rock. There is no “give” or “cushiness.” It’s not all that different from sleeping on a slab of concrete, albeit with a few layers of foam on top. For someone like me, I still “bottom out” and my body aches from the hard support.

While the OSO Mattress also has a six-inch layer of support foam, it’s not a solid piece of foam. Rather, it’s inside this layer that the foam springs reside. The springs keep the surface soft and cushiony, providing more “sink” and “give” that molds more easily to your body as you turn or move throughout the night.

Much to my delight and surprise, after sleeping on the OSO Mattress for nearly two months, I can honestly say I’ve experienced fewer sleep interruptions due to back pain than I have in years. I’m dreaming more, sleeping deeper. It’s still not perfect – I’m not sure it ever will be, but there have been mornings here and there that I’ve woken up completely pain-free, something I haven’t experienced in years. As far as I’m concerned, it’s the best mattress I’ve ever tried.

Better sleep, better beauty

Look, no makeup! Lovin’ the soft side of the bed.

When I first spoke with OSO, yes, I was concerned with sleeping better, but at that point, I had kinda given up on sleeping pain-free. Really, I just wanted to sleep well enough that I would look better in the morning. The sleep experts at the company felt my pain and wanted to help me out. First, they shipped me a mattress to test drive (thanks, OSO!), but they also offered a few tips for making my sleep experience a more beautifying one.

According to the OSO experts, “When you go to sleep, your body enters repair mode; skin cells generate and replace older cells, and important hormonal and metabolic processes take place. Your body needs ample time for this important work, and cutting it short means the difference between the glowing, rejuvenated look of the well-rested and the ashy, dull-haired, puffy-eyed appearance of the sleep-deprived.” In addition to, you know, getting more (and more restful) sleep, they offered the following tips for turning a basic night’s sleep into true beauty sleep.

1. Wash your face before bed

Sleeping with makeup, oil and other residue on your skin is a recipe for clogged pores and breakouts.

2. Moisturize!

It’s easy to underestimate the amount of hydration your body needs, and night is a prime time for dehydration, which can, in turn, lead to wrinkles. Before you crawl into bed, apply a moisturizing cream to your (freshly cleansed) face. And for bonus points, invest in a humidifier!

3. Buy a low-friction pillowcase


The less friction between your hair, skin and pillowcase, the better. A rough surface and lead to tangles, breakage and frizzy hair, and creases and wrinkles on your skin. Choosing a “slippery” material like satin pillowcase or high thread-count cotton enables your skin and hair to glide smoothly across the pillowcase, minimizing any short- or long-term damage.

4. Wear your hair in a loose bun

Leaving your hair loose when you sleep can lead to tangles, frizz and the transfer or oils from your hair to your face. A tight ponytail, on the other hand, pulls at your scalp and follicles, while leaving a telltale crease. A loose bun is the perfect solution. If your hair is particularly prone to frizz, or you’re not ready to invest in a new pillowcase, another great option is to tie your hair up in a satin scarf.

5. Sleep with your head slightly elevated

In addition to helping with head and neck support, sleeping with your head slightly elevated can help reduce morning puffiness around your eyes. If you’re looking for a way to sleep more propped up, consider Reverie’s Sweet Slumber Adjustable Pillow.

6. Change and clean your pillowcases often!

This one is less glam, but it’s just as important (especially if you’re like me and share your bed with dogs who think your pillows are their own). No matter how much you clean up before bed, you’re still subjecting your pillowcase (and sheets, for that matter) to night after night of oil, dirt and germs. Have a few high-quality pillowcases in rotation, and wash them regularly.

So tell me – what’s your mattress like? Do you love it, hate it? Have you tried a bed-in-the-box system yet? What tips do you have for waking up feeling refreshed and beautiful?
