A PregoPillow SET includes 2 stackable foam pillows: 
A smaller-sized pillow for the beginning stages of pregnancy
A medium-sized pillow for mid-pregnancy
The 2 pillows also fit together to be stacked for later in pregnancy or bigger bellies.
 
SIZE: 16" x 24"​
 
What are PregoPillows made of? We use industrial, professional-grade memory foam that supports the weight of mama & sweet baby. (Heck, I recovered my Gonstead bench with this Tempurpedic-style memory foam!) This makes it super comfy for mama to lay face down on like a memory foam bed, yet still have her pregnant belly fully supported.
 
What about the foam casings?
Each PregoPillow has a cotton/upholstery cotton fabric liner over the memory foam to provide extra protection & support.
 
Side Effects: We know the side effect of a good chiropractic adjustment may reinforce the lays of gravity- what goes in, must come out! ;) For that reason we try to protect your investment with a casing + cover.
 
DURABILITY: A washable, removable cover for each pregnancy pillow covers the cotton casing. Removable covers are made from upholstery grade fabric, similar in thickness and density to denim.
