Thick, Supportive, and Cozy for Reading or Nursing
Size: Full, Color: Olive Green
This wedge pillow has been a great fit on my daughter’s bed. It’s super soft and cozy, and at the same time offers great support for sitting up in bed. The pillow is nice and thick, so you don’t sink into it — perfect for reading, studying, or lounging without needing multiple regular pillows.
I tried it out myself and was surprised at how well it also works as support while nursing an infant. It props you up at just the right angle and feels stable without shifting around.
The removable, washable cover is a big plus, and the olive green color is subtle yet stylish. I’m impressed enough that I’ll either be purchasing one for myself soon or adding it to my Christmas list.

Buttons
Size: King, Color: Dark Grey
Here's what I like:
Appearance. I like the color and how it looks on my bed. It looks appropriate for a king sized bed.
Removable cover. It was easy to take the cover off and wash, which I appreciate because I like my bedding to smell fresh and clean.
What I don't like:
It is a bit softer than I would like. But I can live with it. I thought it was a foam pillow inside, not fill. Maybe my fault though for not reading description or reviews.
Quality. This is the biggest issue driving the rating. I removed the over upon opening the item so I could wash it. The buttons are attached the the inside cover. When removing the outside cover, you have to unbotton them. They are not secured well at all. From what I can tell the threading goes through the inside cover through the fill to the button on the opposite side. I suspect this because 4 buttons came off when I removed the outside cover. They are very loosely secured to each other. Be gentle when removing and replacing the cover. Now I will have to thread the buttons again and secure it. Just a pain for a brand new item.
Should I expect that for the cost of the item? I dunno. Could have been a higher rating, but, damn those buttons.

Great Pillow! Could use some improvements
We really like this pillow! It is a good firmness, and helps fill the gap that is often between our headboard and mattress.
Only complain is that almost all of the buttons have fallen off. We have had this for about 2 months.
You also can’t take the cover off of it to clean, which would be a nice feature.

Pretty, but very practical.
Size: Full, Color: Mint Green
The color was exactly what I expected from the photo. It arrived in an unbelievably small package, but expanded quickly once I opened the bag. I waited the recommended 24 hours to be sure it was done. I am pleased that the length is a perfect fit, and I like that it comes up to the back of my neck when I'm sitting in bed. It is a bit softer than I originally imagined, but not so soft that I feel like I'm sinking through it. It's very pleasantly supportive. The fabric is like a soft ribbed corduroy with piping along the outer seam. It looks nice. Both ends have a pocket that is barely noticeable, but is the perfect size to keep your phone close by. I'm temporarily homebound and spending a lot of time sitting in bed, so I'm very glad I invested in this pillow for comfort and convenience. If you ever have trouble with pillows working their way under the edge of the headboard, and into the dusty space between the headboard and the wall, consider this problem solved.
