A problem a lot of reviewers talk about is that this thing is hard. That's not necessarily a bad thing, the core has to be hard in order to keep you upright without full on sinking into the thing. The problem is that the comfort layer on this wedge is pathetically thin (see picture 1) so after a few hours it feels like you're leaning against a rock and becomes uncomfortable.You can actually solve this problem by adding a thin slice of poly foam into the protective case (you can find some here http://amzn.to/2a5X9hS). This will make it much more comfortable if you're willing to do a little foam cutting. (The case will keep the foam pretty restricted, but using an adhesive http://amzn.to/29TKSSx will further help to make sure it doesn't move around.) You can even keep the excess foam for something else that needs padding.Anyway, technically this wedge also has two angles, but i've never found myself using anything but the shallower one because the other one sits you so far up its uncomfortable (see picture 3). The shallower angle i've found to be very comfortable though and I use it while watching TV / playing video games on the bed all the time (picture 2). The pillow I use on and off, it could stand for some more comfortable foam as well.So overall its good, but in my opinion it could be better if they had just added a bit more comfort foam.Note: You'll have trouble fitting it back in the original box if you want to return it because it comes pretty compressed. However, If you end up not liking it you can always modify it. It is better than most of the other wedges out there (its just that most of the other wedges are bad)Edit: I've noticed the price of this wedge has gone up considerably since when I bought it. I bought it open box for 70$, which i think is a decent price for it. However, I would not pay over 100$ for this. Its just foam guys.I love to "sit" in bed and read, use my tablet, watch movies etc. However, over the years I've tried every shape and size pillow and back rest I could find that I hoped would fit my small frame (5 ft) and provide support for my lower back since I don't want to have to sit upright. The quest went on for many years.And then, I found the Jobri! I couldn't believe it and kept avoiding throwing out the box thinking it wouldn't "really" work and I'd want to return it. But it's now3 been about 2 months and I continue to be more comfortable, with my lower back adequately supported, than I've ever been before.The bed wedge can be placed in two positions: one is more upright, closer to sitting, and the other is more like slouching, but with lower back support and enough angle to keep you reasonably upright. The neck pillow is also adjustable and can be used in either position and put pretty much anywhere. The wedge is hard enough but not so hard that you feel constrained.I use this for reading, slouching and waching a movie. I also use it with a computer bed stand and it allows me to use my portable, or my portable touch screen, by adjusting the stand.A Real Winner for me and my particular needs. The cover unzips and can be laundered. The only wish I have is that Jobri sells other covers, perhaps in darker colors (so that they show normal use and wear less easily). On the other hand, the cover is made of a very soft and comfortable material.Some reviewers have complained this is too narrow. I don't find it so. I appreciate that it is narrow enough for my arms to be free at any angle and so that it doesn't take up the WHOLE bed.I highly recommend this backrest to anyone who has spine, back or neck problems. When I first received this, I was looking for something to replace my old backrest that was falling apart. I used that one mainly for reading in bed, but after I had eye surgery, I slept on it as well. So when I received this bed wedge, I was not at first impressed. It didn't feel all that comfortable, no way could I sleep on it, and I actually put it away thinking I would probably never use it.Well. Then I herniated a disc in my neck, and it became apparent that I could no longer sit in bed and read in a slumped position. Not only was this probably one of the contributors to my problem, but it now became impossibly painful to sit this way. After trying everything, and still in pain, I pulled out this wedge. Ahhhh! The relief was immediate. Yes, this pillow forces you to have good posture, which is exactly why it is called a "spine" pillow. No, it may not feel comfortable to you if you like a backrest you can slouch down on. That would be virtually impossible with this wedge, but I promise, your spine will thank you.So my only complaints are 1) the little attached pillow is pretty worthless. I just removed it, and go without it most of the time. If I feel like I need something, I'll tuck a neck roll behind my neck, and that works for me, and 2) I wish it had armrests. That would make it perfect. Otherwise, I now love it.Fantastic productJ'adore ce coussin , j'en avais tellement marre d'avoir mal au dos .J'étais obligé de metre 3 coussins derrière mon dos et encore ça n'allait pas du tout .Je passe beaucoup de temps à regarder mon ordinateur sur mon lit ( la chaise , je n'aime pas ) et il m'arrivais d'avoir très mal au dos .Ce coussin est très rigide et moelleux à la fois , c'est simple je ne me soucie plus de mon dos maintenant .Je mesure 1m80 mais même pour quelqu'un de plus petit , je suis certain qu'il n'y a pas de problème .Je ne suis pas du genre à m'extasier facilement mais là je suis très content et je ne regrette pas mon achat .120€ , c'est élevé mais la qualité ça se paie et je n'ai aucune envie de me faire opérer du dos !!!Mon seul regret c'est de ne pas l'avoir acheté avant car je ne savais pas que ça existait .Et encore quand je l'ai vu , j'ai hésité car il n'y avait aucun commentaires !!!Parfait pour lire , regarder la télé ou l'ordinateur !!!La livraison : commandé le lundi matin à 8h , reçu le mardi à 14h .I found this item very uncomfortable to use. I would not recommend anyone purchasing it unless they have a specific medical reason for doing so.I have given this bed wedge a 4 star rating mainly because it has taken me a week to discover that it works better for me under the mattress. Great pity the instructions did not give me the hint that under certain conditions it is far better under the mattress than as a stand alone. I have been living in a lazy-boy recliner since my accident as I can no longer use a bed. Rather than going all out for an orthopaedic bed I opted initially to try a wedge, I couldn’t be more pleased as it now works exactly as I hoped it would.
