Which incline should I start with — the single height or stacked?
Most people start with the lower single section for the first few nights. It's a gentle 7° rise that's easy to get used to. If you have stronger reflux symptoms, or your doctor has suggested a steeper angle, stack both sections for roughly 12°. You can change it any night, so it's worth trying both and seeing which one you wake up feeling best on.
Will I still be able to sleep on my side?
Yes. The slope is wide enough to support side sleeping along the incline — many side and back sleepers use it without any trouble. If you're broad-shouldered or like to spread out, the single (lower) setting tends to feel more natural for side sleeping than the full stacked height. A handful of larger reviewers do wish it were a touch wider, which is honest feedback worth knowing.
Does it really stay cool, or is that just marketing?
The comfort layer is gel-infused memory foam, and the zip cover is a breathable bamboo-rayon knit that feels cool to the touch — both help move heat away instead of trapping it the way a dense foam triangle does. It won't feel like an ice pack, but reviewers who avoided wedges specifically because foam runs hot consistently say this one sleeps noticeably cooler than they expected.
Is this a medical device? Can it treat my GERD or sleep apnea?
No — the SleepZip wedge is a comfort and positioning pillow, not a medical device, and it isn't a treatment or cure for any condition. Sleeping on an incline is a positioning approach many doctors suggest alongside their care, and a lot of our customers find it helps. But if you have GERD, sleep apnea, or are recovering from surgery, please follow your own doctor's guidance.
How do I clean it?
The cover unzips completely and is machine washable — wash cold on a gentle cycle and air dry or tumble low. We don't recommend washing the foam itself; spot-clean it if needed and let it air out. Because the whole cover comes off, it's a lot easier to keep fresh than wedges with a cover sewn on.
What does the 60-night trial cover, and how do returns work?
Sleep on it for up to 60 nights. If it's not right for you, email us at support@sleepzip.com and we'll set up a return for a full refund of the product price — no restocking fee. We just ask that you give it at least two weeks, since most people need a few nights to adjust to sleeping on an incline. Full details are on our Refund Policy page.
