Pregnancy pillows can look almost identical in photos, yet the cover material changes how the pillow feels during the night. If you are comparing a cooling pregnancy pillow with a jersey-covered model, focus on temperature, texture, washing, bed space, and how much adjustability you want.
Quick answer: a cooling-cover pillow is the stronger choice for a warm bedroom or someone who regularly wakes up hot. A jersey-cover pillow may suit someone who prefers a familiar, T-shirt-like texture and wants adjustable fill. Both JAMGatcha options below use a 57-inch U-shaped design.

Choose the cooling cover if heat is your main problem
The gray model is marketed with a heat-dissipating cover. That makes it the more logical option if your room runs warm, you use heavier bedding, or you dislike the feel of heat building beneath you. Its cover is removable and listed as machine washable. The manufacturer says the pillow measures 57 by 30 inches after expansion, so measure the usable width of your bed before ordering.
There are two limits worth knowing. “Cooling” describes the cover material; it does not mean the pillow actively lowers the room temperature. Your sheets, mattress protector, pajamas, thermostat, and personal comfort can still affect how warm you feel. The current listing also recommends allowing 48 to 72 hours for the compressed pillow to expand before first use.
Choose jersey if texture and fill adjustment matter more
The pink model uses a jersey-knit cotton cover. Jersey often feels familiar because it has a soft knit texture similar to a comfortable T-shirt. Its listing also says the polyfill can be added or reduced in different areas. That may help shoppers who want to change how full the pillow feels around the belly, back, knees, or legs.
The tradeoff is temperature. A soft knit cover can feel warmer than fabric designed to dissipate heat. Also, adjustable fill requires a little setup: changing the fill in one section can alter the support and shape somewhere else. Check the closure, cover-care instructions, and fill-adjustment directions when the pillow arrives.
Check your bed before choosing either one
A full-body U-shaped pillow surrounds the sleeper on both sides. That can be useful when changing from one side to the other because the pillow does not need to be moved across the bed. It also occupies more space than a wedge or a single straight body pillow.
Measure the space between your normal sleeping position and the edge of the mattress. If you share a full- or queen-size bed, discuss the width with your partner before buying. Consider where the pillow will go during the day and whether you can easily remove and wash the cover. A smaller wedge may be more practical for travel, limited storage, or a crowded bed.
What support do you actually need?
Before choosing a large pillow, identify the area you are trying to support. A pillow between the knees, one under the belly, or a full-length body pillow may help with positioning. The American College of Obstetricians and Gynecologists says side sleeping may be best during the second and third trimesters and notes that pillows between the knees and under the belly can help. Its guidance also mentions a full-length body pillow as an option.
A pregnancy pillow is a comfort and positioning product, not a treatment for persistent pain, numbness, breathing problems, or sleep disorders. Discuss ongoing or severe symptoms with your prenatal clinician.
Who should skip a 57-inch U-shaped pillow?
- Anyone who has very limited mattress space
- A shopper who wants a compact pillow for frequent travel
- Someone who dislikes feeling surrounded by bedding
- A person who only needs targeted belly or knee support
- Anyone unwilling to store a large pillow during the day
Our practical verdict
Choose the gray cooling-cover model when warmth is the deciding issue and you want a removable, machine-washable cover. Choose the pink jersey-cover model when you prefer a soft knit surface and want the option to adjust the fill.
For a baby-shower purchase, confirm the recipient’s bed size, usual sleep temperature, preferred texture, and available storage first. If you are also building a practical gift, see our guide to deciding whether a 30-piece baby layette set is useful.
