Q: How does the cushion come boxed? (The box packaging) It's for a gift. Does someone have an image they can share, please?

It comes in a brown cardboard box. The pillow is squished into a plastic bag. You must wrestle the pillow from the bag and allow to sit and fluff up. My advice- buy something else. This was gifted to me on Monday. Under 140 pounds, sat on it for 5 minutes. The pillow was flat and I could feel my tailbone touching the seat through the hole in the cushion. They do not provide an invoice, packing slip, info on how to return or who this was a gift from. I emailed twice- no reply. Rcvd a c/b a few minutes ago but they can’t find any info for my pillow. I sure how to return. This item is way too expensive for what it is and it doesn’t do what it says. I am so appreciative to be thought of and that someone is willing to spend this much on a special pillow to help me but this pillow is a fail. I was sent the seat cushion and lumbar pillow. The lumbar pillow hasn’t really been tested much (I’m not over the moon about it).

Q: How is the seat cushion for bigger people, 6'6" around 380 lbs? Will it hold?

I am in a similar category - 6'5' ~ 350 lbs -- I did not like it -- it is too small -- it hits my legs in the wrong place -- and ( for my liking ) is NOT wide enough ....it requires constant adjustment to remain comfortable

Q: The photo says 16x16x3, the description says 15.5 x 18 x 4 inches. Which one is correct?

I found the dimensions for standard and large sizes per the manufacturer: Standard: 18 W x 15.5 L x 4 H inches Large: 21 W x 18 L x 5 H inches
