Momcozy is the name most people meet first in this category, and the pillow behind it is a 57 inch U with a removable cover. It carries one of the largest review counts of any maternity pillow on the market, which is both a reason to take it seriously and a reason to read past the star rating, because a product that popular collects every kind of owner.
The catalog looks bigger than it is. Strip away the color options and there are really three decisions: the standard cover or the cooling one, whether you want the portable wedge that ships with one version, and whether 57 inches is the right size for your bed at all. This guide takes those in order.

Quick Answer
Which Momcozy pregnancy pillow should you buy?
- The 57 inch U with the standard removable cover is the default and the one most people mean.
- Take the cooling cover version if you sleep warm or are pregnant through a summer.
- The bundle with the portable W shaped wedge is worth it if you travel or want a sofa piece.
- Skip the full U entirely if your bed is a full size and shared, and look at the portable wedge on its own.
Bottom line: same pillow, three covers, one size. Choose on temperature and bed space rather than on features.
What You Are Actually Buying
A Momcozy pregnancy pillow is a 57 inch U shaped full body pillow with a fiber fill, a removable machine washable cover, and two adjustment features that set it apart from most of the field. Zippered access in the outer shell and the lining lets you add or remove fill, and a hook and loop fastening lets you change the distance between the two arms.
Those two adjustments are the real argument for the brand. Most U shaped pillows arrive at one firmness and one width and stay there. Being able to firm up the head end and open out the arms as the bump grows is the difference between a pillow that fits you in month five and one that still fits in month eight.
The fill and the cover
Momcozy describes the fill as a long fiber cotton style stuffing chosen to balance softness with support, and sells the cover separately as well, listed as fitting most 55 and 57 inch U shaped pillows. That last detail matters more than it sounds, because covers in this category are sized to length and a mismatch is the most common ordering mistake.
Standard Cover or Cooling Cover
This is the only decision that changes how the pillow feels rather than what it does. The standard version ships with a removable jersey style cover. The cooling version ships with a cover the brand describes as designed to disperse heat, aimed at summer and at people who run warm, and it is removable and machine washable in the same way.
If you are pregnant through warm months, take the cooling cover. Owners who abandon large body pillows overwhelmingly cite heat rather than comfort, and the cover is the part touching you. Our cooling pregnancy pillow guide compares what different fabrics actually do.
Best all round choice
The 57 inch U with the standard removable cover is the version most people buy, and the one the brand’s reputation rests on. Full wrap support, adjustable fill, washable cover.
Best if you sleep warm
The same pillow with the cooling cover. Nothing else changes, which makes this an easy upgrade to justify if summer falls in the middle of your pregnancy.
The Portable W Shaped Wedge
Momcozy also sells a portable maternity pillow, an adjustable W shaped piece that supports the bump, the back and the hips and folds down for travel. It is sold on its own and it also ships bundled with one version of the cooling U, which is the best value route if you want both.
It is genuinely useful beyond travel. It works on the sofa, in a chair, and as the small piece you use once the big pillow feels like too much. It is also the sensible choice for anyone whose bed cannot take a 57 inch U in the first place, which is a bigger group than the listings suggest.
Best if you travel or want a smaller everyday piece
The portable W shaped pillow packs flat and unfolds into real support, which a plain wedge cannot do and a full U will not fit into a bag.
What Owners Complain About
Three complaints recur, and none of them is a defect. The first is bed space: a 57 inch U takes roughly half a standard mattress and partners notice within a week. That is inherent to the shape rather than to the brand, and pregnancy pillows for a small bed covers the ways around it.
The second is heat, which the cooling cover exists to answer. The third is that the fill settles over time and the pillow loses loft, particularly at the head end where most of the weight goes. That is what the zippers are for, and topping up beats replacing. Our article on pillows that lose their shape covers the fills that hold up.
The one thing to check before ordering
Measure from the top of your head to just below your knees while lying on your side. If that is longer than the pillow, the curve will sit at your shoulder rather than under your head and the pillow will feel wrong for reasons you cannot place. Our sizing guide works through it.

How It Compares to the Rest
Against Queen Rose, Momcozy trades a slightly shorter standard length for the adjustable fill, and Queen Rose answers with a 60 inch extra long version that Momcozy does not match. Against PharMeDoc, Momcozy is the more refined product and PharMeDoc is the value pick with a detachable extension. Against Leachco, it is simply a different shape argument, U against C.
If you are still deciding between brands rather than between versions, our brand comparison puts them in one table, and the main pregnancy pillow guide starts from the shape question instead.
Frequently Asked Questions
Will it take up the whole bed? It will take up about half of a standard mattress, which is the single most common owner complaint about any 57 inch U. If you share a full size bed, the portable wedge or a C shaped pillow is the more realistic buy.
Is the cooling cover worth it? If any part of your pregnancy falls in warm weather, yes. Heat is the reason large body pillows get abandoned, and the cover is the only part in contact with you. Both versions are otherwise the same pillow.
Can I make it firmer? Yes. The zippered access in the shell and lining is there so you can add or remove fill, which is unusual in this price bracket and the main practical advantage over most competitors.
Can I buy just the cover? Momcozy sells a U shaped cover listed as fitting most 55 and 57 inch pillows. Buying a second one is the cheapest upgrade in this category, since it means one is always in the wash. See pregnancy pillow covers.
Can I keep using it after the birth? Many owners do, for propping and for sitting up. It is not a feeding pillow and it is never a sleep surface for a baby. Our guide to using it afterwards covers what it is genuinely good for.
The Bottom Line
Momcozy makes one pillow in three wrappers, and the version to buy depends on temperature and bed space rather than on features. Take the cooling cover if summer is in the middle of your pregnancy, take the bundle if you want something portable, and take the wedge alone if a 57 inch U was never going to fit your bed. The adjustable fill is the reason to prefer it over most rivals. Read next: the main pregnancy pillow guide, and Queen Rose for the extra long alternative.
