Great pillow to relax with.
I ordered this pillow specifically, so my son has something to sit against when he comes to work with me. He absolutely loves it, the pockets are great, it provides enough comfort and support for him to play his video games and read while I get things done.
It does need a couple of days to fully settle and puff up, and there is a bit of a smell as there is with most pillows that have this time of filling and are smooshed and wrapped in plastic. That smell goes away in the couple of days it takes for the pillow to fully expand.
This pillow is great for lounging, kids sitting on the floor watching movies, to using it in bed to sit up and read, play video games or study. It also would work really well for deeper couches and shorter people. I love that the cover is washable, as that is pretty mandatory in our house with kids and pets. I am very impressed with the quality.

Size of backrest much shorter than I wanted.
Pillow has an odor that will not go away. I have put it outside for a day and even after a week it still smells.

Lounge pillow
Support:
I had surgery and needed all around support with comfort.
Ease of use:
The little handle on the top makes it easy to move around as needed.
Comfort:
The pillow is firm but also comfortable for being in one spot for a period of time.

Comfy back support for lounging
This lounger cushion is very comfortable and supportive and works great in the bed, on the couch, or even the floor when additional back support is needed for reading and other activities requiring you to be propped up.
The size is more suitable to small to average size persons. Larger frame people may find it too small for their needs due to the width and height proportions.
The cushion ships. Compressed into a small package and needs to be fluffed up a bit before use. The one I received expanded fairly quickly and was usable right away, but the instructions say to give it 24 hours to fully expand.
The built in handle makes it easy to drag around to different spots. It also has zippers that allow you to gain access to the inside in case you want to remove some of the fill to adjust the softness to your liking. I found the amount of fill to be perfect as is.
The is an excellent lounging pillow that feels well made, is comfortable, and attractive.
