Perfect Pillows

Alli March 12, 2026

These come vacuum sealed so they are flatter when you open them. I had read a review to throw them in the dryer for a few minutes to puff them up! I'm so glad I saw that review because after I did this the pillows looked puffy like I had bought them from the store!

affordable

samantha March 17, 2026

I recently picked up the Mainstays back and side sleeper bed pillow, and for the price, it's a pretty solid option. It has a firmer feel, which gives good support for your neck and head—especially if you sleep on your side or back. The pillow feels full and holds its shape well at first, providing enough loft to keep your spine aligned and comfortable through the night. It's also lightweight and breathable, so it doesn't trap too much heat while you're sleeping. After using it for a while, I did notice it starts to flatten a bit, which seems pretty common with pillows in this price range. Still, it fluffs back up easily and continues to offer decent support for everyday use. Many users say it strikes a nice balance between firm and comfortable, though it may not be ideal for stomach sleepers who prefer something thinner. The material feels simple but durable enough, and it's easy to care for, which makes it a practical choice for regular use or even a guest room. Overall, this is a great budget-friendly pillow that provides good support and comfort without spending a lot. It's not luxury quality, but it definitely gets the job done and is worth it for the price.

Product arrived vacuum sealed. Once opened they were nice and fluffy. Put them in the dryer for a few minutes based on the instructions and they were perfect! I could not find a better price anywhere else!

Disappointed

PrincessMommy17 January 19, 2026

These were purchased for sham stuffers and extras for company. The seams are very narrow. So narrow in fact they have pulled upon in parts with no use. Don't foresee them holding up well in a washing machine but then again as sham stuffers only they will do.

Won't buy again

Chaniqua February 12, 2025

They went flat within a week and nothing you do will make them flies again, I fluff every morning when making the bed but the cotton in these keeps their shape from tossing and turning all night

Soft and fluffy pillows

Liliana January 5, 2026

Nice pillows but I don't think these are extra firm. They are more of a soft/medium and fluffy.

Not firm at all

Haylee February 2, 2026

To put it plainly these are supposed to be extra firm. These are not even slightly firm. They're soft. But for side sleepers we definitely need a bit of neck support and this doesn't provide it even with two of them stacked up on each other. But they didn't stink, and again they're soft. Just no where near firm. So disappointed in the buy because I didn't need a soft pillow.

Horrible and pricey pillows

Yvette October 22, 2025

This is not at all a firm pillow. Quality is horrible. Would not purchase again nor recommend The way it was sent to me in the box was they placed the pillows (4) rolled up together ! Horrible packaging, Walmart doesn't care at all anymore about their customers.

The king size pillows I got were way smaller than my other king size pillows. They weren't large enough for my pillow cases nor shams.
