Definitely not firm support. Id say more like medium-flat support.

[This review was collected as part of a promotion.] This pillow is different! It has zippers on the long edges to help change the firmness of the pillow. Awesome! I actually found leaving one side zipped and one unzipped fit me the best. My sister was visiting from out of state when these arrived. She loves the pillow so much, she took it home with her.

[This review was collected as part of a promotion.] Solid8 pillow has two zippers to change the shape and firmness of the pillow. It took me a while to use in bed because it was a bit high for my neck. It takes me some time to get a pillow in the shape I like. I use it mostly for leaning against the wall sitting up since it is fluffy and light. Not bulky at all. It retains its shape and the allergen barrier is really great in keeping the dust fiber away.

[This review was collected as part of a promotion.] I have become pretty sensitive to dust and allergens in the past few years. The worst symptoms being at night, causing a lot of coughing and lost sleep. But I really have noticed a difference after using the Solid8 Comfort Zip Pillow with Allergen Barrier

[This review was collected as part of a promotion.] I love these pillows. I have four of them and they are quality made. They have nice fabric and we’ll made. They are comfortable to sleep on and clean. I like the zipper to make it firm.
