Caldera Releaf Neck Rest, Large, Jade and Black

I now have four of these - One Jade/Black, one Black/Black and two Granite/Black. I bought my first one several years ago from an in-flight catalog; the other three are recent purchases from Amazon. I have had some neck problems since a traffic accident nearly 20 years ago, which have become worse over the last five years even with fusion of three vertebrae. The Caldera Releaf collar is Not A Medical Device, but they have given me more comfort than any of the medical device foam collars I have had over those years. It is an actual engineered product (not just a block of foam wrapped in scratchy fabric and approved by the regulatory agencies.) The Releaf collar is designed for sleeping primarily while seated or reclining, such as on an airplane flight. (That is why I bought that first one several years ago.) The collar is fairly stiff in the vertical direction, in order to support your head comfortably when sleeping in those positions. I works wonderfully for that purpose. I have found that it also provides comfort during activities such as driving, working at a desk, reading or similar activities. I have found that it is uncomfortable to wear when exercising or laboring (it gets very hot and sweaty) or while lying down (it presses on the side of my neck too much when I sleep on my side.) The hook-and-loop fastener has about five inches (127 mm) of range. Worn correctly, so you can slip two fingers between the collar and your neck, it should not restrict breathing PROVIDED you have the correct size. (For example, I wear a US 18-inch neck size dress shirt and a Medium is too tight for me.) I find this to be very comfortable when used as intended, much more comfortable than the medical device collars. It is also less bulky than the medical devices. I clean these in the normal cold or warm water laundry (no chlorine bleach, and With the hook-and-loop fastener closed!) and air-dry them. I highly recommend them for anyone who needs head support while flying or driving, and for certain other activities.

I got this neck rest to support my head between my cervical nerve ablations. I don't need a sturdy neck brace but I'm unable to hold my head up or even lay down without severe muscle spasms and headaches while waiting for my next procedure. This product has allowed me to sleep much better and to be able to sit up without ending up in agony after a few minutes. If I can survive these few weeks then I can keep putting off surgery so this is a huge win for me to find this neck rest. I was grateful for the other reviews insisting this works better than a soft cervical collar. I agree.

Muy bueno para esos días que amaneces muy tenso, te ayuda pero hay que hacer ejercicio si no te sigues consintiendo y lo vas a usar siempre

It's ok ,but it does not provide enough support for someone with a LONGER neck. I wish they had more sizing options. It is VERY comfortable and soft enough to take a nap in if you can handle the extra around your neck.

I needed a way to keep my mouth from dropping open in my sleep during cpap therapy. After trying several methods (chin straps didn’t work and mouth tape while effective makes me uncomfortable) I decided to try a cervical collar and this was recommended in a Reddit post I saw. This (size large) was a little too big, so I ordered a medium and it works perfectly at night by supporting me under the chin and keeping my mouth closed while I sleep. It doesn’t interfere at all with my cpap mask. Make sure to measure your neck circumference before choosing what size to get.
