Derila Ergo: how long should I give it before deciding?

Give it a week, mine felt odd too at first.

I gave mine about ten days before I made up my mind. The odd neck feeling faded somewhere in the middle of that, but the height still wasn’t right for how I sleep. That’s the part nobody can tell you, it just depends on your body.

Mine actually felt pretty good from the first night, so I don’t think the weird feeling is something everyone gets. The thing that sold me was waking up without that usual stiff spot between my shoulders. If it still feels off after a bit, that’s a different story.

I actually don’t think you need a full week to know. My neck felt off for maybe three nights and then it clicked, so if it still feels wrong after that I’d probably try a different height. Not every pillow works for every person.

A few days tells you basically nothing with these. I stuck with mine for two solid weeks before my neck stopped noticing the shape at all, and that was with normal use every night. If you bail at four or five nights you’re judging it before your body has adjusted.

Two weeks is the number I’d go with. Anything under that and you’re mostly just feeling the newness of the shape, not whether it actually helps.

I sleep on my stomach mostly, which is probably why no ergonomic pillow ever works for me. My preference is a flat, cheap pillow I can basically ignore, and anything with a shape to it just fights me all night. So when something feels weird on my neck right away, for me that’s usually a sign it’s not going to suddenly become comfortable. I’ve tried a couple of the shaped ones over the years and the odd feeling never really went away, it just stayed odd. If your mornings aren’t any worse and you actually sleep on your back or side, that’s a different situation than mine. But for me, if the shape bugs me at bedtime, that feeling tends to stick around.

A week is usually my cutoff for anything like this. I tried a different ergonomic pillow last year and gave it about 8 or 9 nights. By then I either stop noticing the shape or I don’t, and that was enough to know. If it still feels off after that, it’s probably not going to suddenly click on night 12.

The neck thing you’re describing sounds normal though. Mine felt strange for the first several nights, just an unfamiliar shape under my head. Not sore, just odd. I kept waking up half aware of it, which made me think it wasn’t working, but that’s more about your body adjusting than the pillow failing.

What I’d actually pay attention to is the morning after, not how it feels when you lie down. If you’re waking up with the same tension you had before, that’s a sign. If the mornings are roughly the same, give it a few more nights. If they’re worse, I’d stop.

I bought a similar shaped pillow last spring and had the same first impression. Weird pressure points, not pain exactly, just my neck not knowing what to do with itself. I kept using it out of laziness more than hope.

What actually made me decide was comparing two mornings. I slept one night on the ergo thing and one night back on my old pillow, then checked how my neck felt when I got up. The difference was small but real, and it showed up around the fourth or fifth night, not the first. If both mornings had felt identical I probably would have stopped.

One thing I noticed is that the first few nights I was unconsciously fighting the shape, like adjusting and re-adjusting. Once I stopped messing with it and just let my head sit where it landed, it got less strange. That took maybe three nights on its own.

I would not drag it out for weeks if nothing changes at all. But a few days is too early to call it, since you are still basically sleeping on a new object. Give it a handful of nights and pay attention to how you feel when you wake up rather than how it feels when you first lie down.

A week is too long, mine was obvious by night three.
