Incredible for EDS and fibromyalgia

“As someone with EDS and fibromyalgia who uses CPAP, this is the first system that actually understands complex sleep needs.”

Elena B.

Nursing is going to be easier

“I’m 32 weeks pregnant and this pillow has been a lifesaver for support and rest. I know I’ll use the arm pillow even more for feeding once the baby arrives.”

Marjorie K.

The difference was immediate

“I track my sleep with a device - first night with this, my deep sleep doubled. Less tossing, no neck pain in the morning.”

Chris J

Safe support after back surgery

“I needed something to stop me from rolling in my sleep during recovery. This held me in place all night without pressure or pain.”

Most people would never spend eight hours standing with bad posture — yet that’s exactly what happens when you sleep.

The Modular Pillow® keeps your body in a clinically supported 45° side tilt, the same position many try to build with stacked pillows, now held securely in place all night.

It relieves pressure, reduces joint strain, and adapts to your body whether you’re hypermobile, recovering from surgery, or sleeping through pregnancy.

1 Octagon Head Pillow — Keeps your neck aligned and posture consistent; its unique shape prevents your arm placement from lifting the corner of your pillow causing neck strain and "dead-arm" sensations.
2 Side Pillows with Arm Support Zones — Built with a 45° tilt to keep your body gently supported and stable through the night.
1 Arm Pillow — Cradles your shoulder into its socket and provides a calming, hug-like sensation for anxiety relief.
2 Full-Leg Pillows — Support your knees and ankles while aligning your hips for full-body stability.

THE PROBLEM

Waking up in pain and still tired?
It’s your sleep posture.

<p>Waking up in pain and still tired?<br/><strong>It’s your sleep posture.</strong></p>

You focus on posture when you sit or stand — but ignore it for the 8 hours your body repairs itself.

When your posture changes every night, so does your pain — shoulder one day, neck the next, or another flare-up or sublux waiting to happen.

When your sleep posture stays consistent, your body finally has the stability it needs to heal without fighting itself.

The Modular Pillow holds you in a gentle 45° side tilt — the same supportive position you’ve been trying to build with a pillow stack, now finally held in place so you can wake with less pain & feel truly rested.

THE SOLUTION

One System.
Six Modular Pieces.

Head Pillow (Octagon)

Angled corners allow the arm to rest beneath without altering pillow height, maintaining cervical alignment.

Side Pillows (x2)

Stabilize torso and hold body in 45° side-lying tilt.

Arm Pillow (Either Side)

Elevates and supports shoulder to offload joint pressure. Works no matter which side you sleep on.

Full Leg Pillows (x2)

Supports ankles to knees for hip alignment and low-back tension relief. Plus, lift straps for easy flips.

Hidden Adjustable Straps

Keeps the system intact all night, even if you toss and turn.

Frequently Asked Questions

Love this pillow so much

I got recommended this by my OB bc all the other pregancy pillws weren't working for me. I'm due in 4 weeks and I'm annoyed at myself for not buying this earlier. It works wonders on my pain (sometimes it was my back, sometimes its my knees somtimes it's my ankles...) and I feel like I'm sleeping deeper. I still get up obvs but I fall right back asleep like it's my own little cocoon!

I would pay $1000 for this

Expensive, annoyingly. But 1000x worth it. I'm sleeping almost an HOUR deeper on my Fitbit!!!

Pregnancy + EDS

I've been recommending this pillow to literally every single one of my mom friends and everyone i see at each hospital baby care class. I have trouble sleeping and this is literally the best pillow I've ever slept with, hands down. I've had bbhugme, I've had the chinese ones from Amazon, Medcline and Pflufl and probably more than I can count. You don't really understand how important sleep is and how you different you feel until you sleep well one night. It's just not comparable. I got one for both my parents as well. Not sure they'll use it lol but it's gifts for the holidays coming up.

Worth it

I was so skeptical at first. It took me a few minutes to get used to the feel of it. Then I just slept the deepest I ever have. For someone with HEDS who dislocates and subluxes joints in sleep frequently then wakes up all night with pins and needles from nerves not getting enough oxygen, it was amazing not to wake up in the night in pain constantly. It supports every sleep position, you just wedge yourself in this perfect nest and your shoulders are held in place. I prefer a firm head pillow and this is firm but also joyously sinkable whilst supporting your neck. I woke up feeling so good I cleaned my entire house then did a 2 hour ballet class with no pain. This provides the recovery so you can live a full life <3

20 years later….......

20 years ago I had a spine injury and have been waking up in pain ever since. This keeps my spine straight and hips in place so I don’t twist at night. Huge difference in the mornings.

Good w/ its pros and cons

It's more of a system than a single pillow. It takes a bit of adjusting and experimenting to get it right, but once everything’s in place, it does improve alignment compared to stacking regular pillows. The arm pillow is a nice touch for side sleeping. On the down side, I found some pirces are a bit too soft for me, but I'm 260lbs so I feel that way about most pillows tbh but thought this could solve it. My partner took if over bc she actually prefers it for hip and knee support and loves it. As an alternative to juggling five pillows every night, it’s worth a try.

helped my sciatica pain

I had awful sciatica in my second trimester and nothing helped until this. Having my hips supported and my legs slightly elevated has made a huge difference. I still use it every night even postpartum because it just feels better on my lower back.

Storage

Storage was annoying bc I like my bed tidy but once I got over that it’s been a blessing

Neck and shoulder pain

I've had 2 shoulder surgeries and my bio mechanics are all messed up so my neck hurts all the time, especially after a bad night of sleep (whether that means little sleep or just bad posture). With this pillow I'm sleeping like 80% better than I can remember in a long time.

Better than floor

Expensive and too firm for me, but im using it when I have severe back pain instead of sleeping on the floor
