Secret Pre-Launch Bundle

SHHHH... Secret Pre Launch Bundle SAVE 60%


Most mattress companies force you to conform to their mattress instead of making a mattress that conforms to you. 

The Pillow Cube Mattress is different. It's an amazing mattress in any position, but it's the first mattress designed to work for those of us who sleep on our side.  

In order to stay comfortable all night long you need to keep your spine aligned

Any mattress can be comfortable if you lay flat on your back. But most of us change positions while we sleep. We roll from our side to our back and everywhere in between. 

The pocketed springs in the base of the mattress are zoned to give you more support under your hips where you need it most, and to be softer at the top so your shoulder can sink in when your on your side. (why hasn't anyone thought of this before?)

On top of those perfect springs we stacked layers of breathable memory foam to give you the perfect amount of cushion for the pushin! 😉

If you currently wake up tired, in pain, with a headache, kink neck or a little sluggish then the side sleeper mattress is perfect for you.

My husband and I had been putting off getting a mattress because it didn't want a Sleep Number again. I had to go through so much to make it comfortable. Last month I received an email about this mattress, and know it was for us. We got the whole deal with sheets, comforter, mattress pad and pillows. I already was in love with my cooling pillow but combined with the mattress I love sleeping and getting up in the morning without hurting. It was heavy to get upstairs and we bought King, but we managed. It is so much better than Sleep Number because the Pillow Cube mattress conforms to your body so that you don't have to play around trying to find your number. I just have FOMO about the new cooling pillow for the side and back sleeper, because that is me. I don't write reviews often but for this mattress and pillows I have because it anyone is on the fence, just do it and you will sleep like a baby.

Couldn't wait to get home

I've been sleeping on this mattress for a few weeks now. I can honestly say that I don't wake up with a stiff back anymore. I sleep on my side and back. My wife sleeps primarily on her side. We both love the mattress. Funny thing, we just got back from a vacation and after hotel beds we both mentioned on the last day how we were looking forward to sleeping on our own mattress!

Supportive Squishmellow

It was actually soft yet supportive like the pictures described. The design of the mattress isn’t bland either, like most other brands. So that’s fun. The quality of the mattress is clearly a 5 star I just prefer a firmer mattress.

Weird but Amazing!

Kinda wierd that a pillow company makes a mattress so obviously I wasn't sure it would work. I'm also a stomach and side sleeper but turns out it's great for both. Maybe cuz the middle is firm so my back doesn't banana-like on my last mattress ‍♂️ . My wife is a side sleeper and aside from sleeping next to me she now loves going to bed. Thanks, Pillow Cube!

I don't know how you make a whole mattress for sleeping on your side. But they did it. Best feeling ever. You honestly just have to try it.

Pleasantly Surprised

I really wouldn't have guessed that it would be so comfortable but I literally have never laid on a more comfortable mattress.


Eliminate side sleeper pain

Soft Shoulder Zone

Shoulders are lower and uncomfortable to sleep on. So we made a pillowy soft layer.

Hip Support Zone

Hips are higher and heavier. So we made a layer with plenty of hip support.

Align your spine with zones

We zone our mattresses because your shoulders are on a whole different level than your hips.

Lower Shoulder Level

If your shoulder is squished under your body you’re in pain. We fixed that!

Higher Hip Level

If your hip isn’t properly supported your spine isn’t aligned. We fixed that too!
