The Perfect Mattress for Side Sleepers

Most mattresses aren’t made for side sleepers. That’s one reason you wake up with shoulder, neck, and back pain. The Pillow Cube Mattress is specifically designed for the needs of side sleepers. The top third is pillowy soft so your shoulder sinks in and the middle is supportive for your hips so that your spine is perfectly aligned. Now you can finally sleep comfortably and wake up refreshed.

What Makes It Different?
  • Firmness: 5/10 (Medium)

  • The shoulder zone reduces pressure on your shoulder to decrease pain

  • The hip zone provides support to align your spine and decrease back pain

  • Our unique, comfy combination of materials makes this mattress not only perfect for side sleepers but one of a kind

MADE FOR SIDE SLEEPERS, BY SIDE SLEEPERS

Old fashioned pillows are made with cheap foam dumped into a sack. But sleepers need more support, and we will try anything to get it; folding, stacking, nothing works.

Pillow Cube fills the gap between your bed and your head, aligns your spine, and supports your noggin.

What if I sleep on my back and side?

Not a problem. Meet our latest addition to the family, the Combo Cube.

Designed for our noncommittal sleepy heads, the Combo Cube is the ultimate pillow for back & side sleepers.

We took our premium cut AeroFoam and sculpted a head-sized valley to cradle your noggin and keep your neck aligned, no matter how you sleep. Then we leveled it up by adding modular risers, giving you the ability to customize the height of your pillow to match your body, mattress, and sleep style.

    An investment worth it's weight in sleep

    I typically sleep on my side, and with the success I've had from my Side Cube pillow, it was a no brainer to purchase a Mattress from Pillow Cube when the time came for a new mattress. I purchased the Deluxe Hybrid Mattress for my new Queen Bed and I could not be more comfortable when I go to sleep (I actually look forward to going to bed). Pairing this mattress with my Side Cube pillow is the perfect combination of comfort and alignment.

    The Deluxe Hybrid Mattress is rated 3/10 in firmness meaning that it is soft and supportive which is exactly what I like. While I can sleep on firm mattresses, they don't work well for me as a side sleeper (I tend to lose feeling in the arm I sleep on). This mattress has the perfect amount of give so that I am not crushing my arm or shoulder and can rest comfortably on my side with my spine aligned perfectly. Ever since I started sleeping on this mattress, I've noticed higher sleep scores in my ring wearable as well. It's been a great addition for my room, and a steady improvement to my health (and overall sleep).

    I liked my Deluxe Hybrid Mattress so much, that I went and purchased a Full Size version for my guest bed. For this purchase, I was assisted by Parker Yandric from Pillow Cube who helped me choose between the various mattress options (I was exploring all three mattress options since this purchase was for a guest bed). Parker was incredibly helpful, he answered my many, many questions, gave insightful recommendations, and he…

    Wow — this is the kind of review that makes us smile from ear to ear. 😄🛏️

    We’re thrilled to hear the Pillow Cube Deluxe Hybrid Mattress has been such a game changer for your sleep, comfort, and overall recovery. Side sleepers know the struggle of shoulders and arms going numb on overly firm mattresses, so hearing that the mattress gives you the perfect balance of softness, support, and alignment is exactly what we hoped to achieve. And pairing it with your Side Cube pillow? That’s basically the dream team. 😎

    The fact that you’re seeing improved sleep scores and looking forward to bedtime says it all. We also love that you trusted us enough to add a second mattress for your guest room — that’s a huge compliment.

    And thank you for the kind words about Parker! We’ll absolutely make sure your feedback is shared with him and the team. We’re lucky to have people who genuinely care about helping customers find the right setup, and it’s awesome to hear he made the experience such a positive one from start to finish.

    Thanks again for such a thoughtful, detailed review — and here’s to many more nights of incredible sleep ahead!

    Excellent!

    To date, the mattress has proven to be an effective solution for my side sleeping needs. It has effectively alleviated any shoulder, hip, or back pain that I experienced previously. Additionally, I am satisfied with the edge support provided when I am sitting on the bed’s edge. While the mattress may retain some heat due to the absence of a cooling cover, I am confident that this issue can be easily addressed by purchasing a separate cooling cover or removing a layer of blanket.

    Fantastic Mattress

    I bought a queen deluxe hybrid mattress from Pillow Cube back in 2023 as I had been enjoying one of their pillows and am posting here to write a long term review. As a side sleeper, I appreciated the fact that this mattress was designed specifically for side sleepers. I've always heard that you should not skimp out on your mattress (and shoes and car tires haha) so I decided to invest some in my sleep when it came time for my first real new mattress.

    Let me tell you, from the first night I have slept fantastic in this bed ever since. It's supremely comfortable and I am so glad I decided to make a purchase. I'm in my early thirties so I don't really get much at my age, but on this mattress I've never had kinks in my neck, no aches from sleeping weird, just cozy and restorative sleep. On other mattress, with other pillows, that had been an occasional thing, perhaps a few times per year but not with the Pillow Cube. Previously I had been used to a medium mattress and would describe this on the soft side of medium. The extra softness has been helpful for me to get the support and coverage I need on my side.

    I also haven't really noticed any significant wear as the mattress has broken in. It still feels as good as it did on day one. I'm looking forward to many more years with it. I do use a mattress protector as well to prevent it from wearing out too quickly from absorbing skin oils, dirt, etc.

    In addition to this mattress I bought a set of the zip fit sheets and a…

    Wow — this review just made our day!

    We’re thrilled to hear your Pillow Cube Deluxe Hybrid Mattress has been hitting all the right notes for side sleeping, from supremely comfortable nights to zero neck kinks or aches. Investing in quality sleep really does pay off, and it sounds like your mattress has delivered exactly that — cozy, supportive, and restorative, night after night.

    Love that you’re also enjoying the ZipFit sheets and comforter! Even though the setup is a little different, it’s great to hear they’re living up to the “better-than-traditional” promise and making your bed routine easier. And yes — the pillow foam can feel a bit firmer when cold, but sounds like your system of mattress + pillows + protector has everything dialed in perfectly.

    Thank you for sharing such a thorough, thoughtful long-term review! Here’s to many more years of incredible sleep, side-sleeper bliss, and cozy mornings.

    So far so good!

    My wife and I are greatly enjoying our new King size mattress. Wife says she has had much less back pain after waking up on this mattress vs. our old one. I, myself have found it very comfortable and have slept much better since getting it. It isn't AS cool (temperature wise), as I hoped, but it is much cooler than any other mattress I have slept on.

    Sounds like the King size Mattress Deluxe Hybrid is already living up to its royal status — less back pain for your wife and better Zzz’s for you? That’s a win in our book. As for the temperature, we’re glad it’s cooler than your previous mattresses, even if it’s not an arctic blast. Thanks for trusting us with your necks and backs. Keep enjoying that sweet, sweet sleep upgrade!
