Such a small amount for the price!! I thought it was ridiculous that I was having to buy more stuffing for the travel pillows I bought from them as is considering the cost of those, but honestly, they were unusable with the small amount of stuffing that came with them. It’s just ridiculous.

I’ve been loving my Coop Original Pillow for many years now, and I love that I can just add some extra fill to extend its life and give it the “extra oomph” it needs! It’s been perfect to get it back up to its original plushness and it’ll help me to continue to use and love my pillow for more years to come!

This was needed

My new Coop pillow did not keep its loft through the night even with the extra filling it came with. Rather than return the pillow I ordered the extra dense filling. This has worked out. I’m not happy that I had to spend additional money for the pillow to act as described by Coop but I am sleeping well now. My feelings are mixed on this purchase.

Nothing like the original stuffing

I absolutely love Coop Pillows. Those are the only pillows we have in the house and the only ones I recommend to family and friends. I upgraded my pillows for the king size bed and the stuffing seemed a bit softer than before. I thought I would just order the pillows extra firm stuffing to make it just right. The extra firm stuffing, even in small quantities, is rock hard. Impossible to sleep and definitely overheats the pillows. I immediately returned the stuffing. Do not recommend.

I bought two of the original pillows. With all of the stuffing and all of the extra stuffing they came with, they’re still a little low loft for me for side sleeping. I ordered one bag of extra fill but what came is more traditional pillow stuffing material than the memory foam. Is the firm extra oomph more of the memory foam or is it the same combination?

Thanks so much for reaching out! The Extra OOMPH firm fill is exactly what you're looking for—it contains only cross-cut memory foam and does not include any microfiber. It's perfect for adding more loft and structure, especially for side sleepers who need that extra support. Let me know if you’d like help placing an order for the firm fill or if you have any other questions—I’m happy to help!

I purchased a pair of king pillows recently and found them to be too soft for me even once I added the included extra “oomph”. If I purchase a bag of this firm full would I have to remove some of the fill already in the pillow? Is it possible to overfill the pillows?

Coop Sleep Goods 07/30/2024

Thank you for reaching out! If you find the king pillows too soft even after adding the included extra fill, you can indeed purchase a bag of firm fill to adjust the firmness further. When adding new fill to your pillows, you may need to remove some of the existing fill to achieve your desired level of firmness and ensure proper support. It’s possible to overfill the pillows, which can affect their comfort and support. To avoid this, gradually add the new fill and test the pillow’s firmness as you go. This way, you can find the right balance that works for you. If you have any other questions or need further assistance, please let us know!

Hello! I have two queen size standard coop pillows that I LOVE! I’ve added the extra foam that came in the box. I find that it is such a soft pillow but it lacks something when I try to sleep on my back. I was thinking of getting another bag of foam to put in but not sure if I should get the standard or mix it up with the extra firm. I know once I add it to the standard foam it will be hard to take it out once it’s all mixed up, so was curious of your opinion. I used to sleep with two pillows…since getting the coop I just use the one but it doesn’t prob my head as high as I like. Thank you so much

Great Question! Once you add the firm fill to the pillow mix it in, it will not be possible to remove this from the foam. Your warranty does cover one additional 1/2lb of extra fill complimentary! Reach out to our customer service team at customerservice@coopsleepgoods.com with your order number and current mailing address and we can get that out to you!

I just purchased a couple bags of the stuffing. Should I remove some of the old stuffing before I add the new or should I just stuff brand new stuff in on top of the old? Thank you.

This will depend on the loft you want to have on the pillow. If you want to increase the loft, you can add the bags and place the pillow on the dryer on low for 30 mins to allow the new and older fill to expand.
