Question: Does the pillowcase that comes with the pillow stay on or should I go ahead and buy a zippered case?
Document: I don't like the core because it is messy and has to be fluffed frequently. The core is surrounded by a zippered pillowcase that is stuffed with something that is not memory foam, and it is soft and fluffy. The case that comes with the pillow is velvety soft and fits like a glove. No complaints there. The only other negative thing is that the pillow retains major heat. This was awful in the summer, I had to stop using it, but in the winter it is very useful.
Yes it is heavy- but that's what makes it hold up. It is perfect for a side sleeper with pain in joints and knees. I will never go back to a plain body pillow again. I thought it might take a night or two to get used to it ,as it is much thicker than any body pillow I've had , but that was not the case. The quality is great and the pillowcase that comes with it is very soft. I would definitely recommend this product.
VERY nice!This body pillow is about 48 inches long and about 17 inches wide. It comes packaged in a zippered plastic carrier and with a soft pillowcase that almost feels like felt. The pillow piece is inside a zippered material that is puffy like a comforter for your bed. So, all said, this is puffy and soft and feels so good.
The quality is very high, it is so soft and washes up beautifully. I wish I knew where to buy sheets in this material.5) the price is a bit stiff. But seeing as I was spending an average of $20 every six months, I still see this as a good value.6) I just washed the zippered case for the first time. This fails. The batting lumped up terribly. Try to avoid washing the zippered case.
This is a quality product. It does not go flat over time like the typical cheaper ones do, and comes with a high quality pillowcase. However, it is VERY heavy for a pillow. Personally, I like this...but my girlfriend does not like it all. It's a matter of personal preference, but if heavy body pillow is what you're looking for it's a win.Update:This must be a larger than average body pillow, as many cases do not fit it.
First let me say this pillow weights more than a bag of bricks! There are ups and downs to this. It does stay in place and is immobile at night, but its a struggle to adjust and move. It is comforable but DO NOT BE FOOLED this is not a solid memory foam pillow, it is a pillow filled with chunks of memory foam so it can feel a little lumpy. The pillow case it comes with though is one of the softest materials I have ever felt! Its amazing.
My feedback is based solely on how bulky this pillow is. As far as memory foam pillows go, this one is pretty good. It consists of a &#34;core&#34; composed of memory foam chunks that you need to separate and distribute evenly when you first pull it out of the box since they've been mashed together during packaging. The outer pillowcase is pretty nice, it's soft and easy to wash. Putting the two together is simple too as the case has a really long zipper.
It is MUCH thicker. It is a heavy pillow. The shipping weight is a hint for those who were suprised when they picked it up. It was compressed in the package but did not require any major fluffing. It comes with a wonderful, soft pillowcase in snowy white.I put the case on and left it alone for about an hour before I went to bed. What a wonderful pillow.I am a side sleeper and need something to put between my knees.
This body pillow is too large and heavy for my taste. It's like having another person in the bed! If you're someone who flips from one side to another you'll have your work cut out for you to maneuver this pillow while switching sides. I find the Pinzon Body Pillow a lot easier to handle and more comfortable for sleeping. However, the pillow case that comes with this body pillow is extremely soft. I wish they sold the case separately--I'd buy several.
You have to fluff it a bit when you first unpack it, but you'll be good from there. It comes with a soft handed pillowcase and a removable, washable inner case. The very inside is made from cheaper material, but no better is really needed. I definitely will purchase this again and recommend it.
Answer: Didn't use it long enough to have that problem. It was too heavy to sleep with for me.  I thought the pillowcase was very soft and WAS surprised at the quality expecting something cheap since it was included.
