I’ve had my Hullo pillow for a little over 6 months now and I’ve loved it the whole time. I prefer firm pillows when I sleep and, before buying this one, would generally get a pillow, use it for maybe a year, and then get gradually worse sleep as the pillow wore out until I grabbed a new one and started the process over again. Though it hasn’t been a year yet, the Hullo has been as solid as when I first got it and has helped my sleep immensely. I will say if you are considering buying one it definitely takes some getting used to and isn’t for everyone. It’s by far the firmest pillow I’ve used (which was great for me it turns out) and when you lay on it you stay put where you laid your head down. Also the sound of the pillow can take some adjusting too since it is a bag full of hulls; it’s not a loud sound, but it is something to get used to if you shift around at night.
Overall, though, I can’t recommend it enough!
