Nice Sleeping Partner
Color: Grey
This is a fantastic body pillow. It comes with the cover and is relatively cooler than the bamboo versions. I have slept with this pillow and I am not disappointed with it, unlike my partner on the other side.

Perfect size even tho I wanted hard/firm. This soft pillow is acceptable.
Color: Grey
I didn’t read every thing properly but even though I got the wrong product ( soft ) it still is not bad. It works for my intended use (between legs ) even though it’s soft I’m still using it for now because after fluffing it out and cramming it in two regular pillow cases it seems to keep a decent thickness to it JUST. In fairness I don’t know if it would get smaller in just one pillow case. But because I’m dumb I will use it for now and I still like it. I can’t comment on the cooling part because I use it under a blanket. The cooling thing only works with low thread count material and if it’s exposed to air. I have neither sorry. We all know the “ cooling” thing is a gimmick any ways. But with the right material and air some things do cool better than others at the same time. Hope this helps lol

wife loves it as a pregnancy pillow
Color: Grey
For my wife's first pregnancy we got a ton of really bad recommendations for pregnancy pillows that ended up being basically useless -- ones with small beads inside that moved away from where she needed it, weird wedge ones that would just fall out of place immediately, the question mark one that was just uncomfortable. all she really needed was something like this. large, firm enough, and doesn't just shift around a bunch. her sleep quality during the second pregnancy third trimester has really improved since we got it.

Not 54" long, only 47.
Color: Grey
Not 54" long. It's the same length as my old 47" pillow, laid them out side by side and the same. Measures 47" with the tape measure. I got it because 47" wasn't long enough. It's soft and comfortable though, so I guess if you need a 47" it's fine. Not what I needed though.
