When your used to sleeping on a pillow thats soft and squishy it takes time to get used to sleeping on something a little harder and not something you sink into, they are harder than a regular pillows, but I do think my neck feels better
One nice thing I've seen from buying from overstock.com is consistency. % years ago we purchased a memory foam queen topper and two queen memory foam pillows. Pillows are an especially hard to buy item because once you get used to a particular density it's hard to find the same one 5 years later! And OS has so many different brands to choose from. I had no idea which brand I bought but to my surprise . . I put in my user name and password and there was my order from 5 years ago. I searched by the same item numbers and OS still sold the exact same items . . . 5 years later. For the price you won't beat this particular brand's memory foam. We also ordered a full topper and another queen and they too have held up well over the past 5 years. We take the queen when traveling for hotel/motel beds. It squishes down real small in a plastic garbage bag when you squeeze the air out as you press it against a wall and then twist and tie the top.
My husband and I like firm pillows but any others we bought flattened out and we end up buying new pillows often. These are holding up wonderfully! The only issue I have is cosmetic. They don't fit perfectly in my queen-sized pillowcases.
Great addition to the same brand mattress. Like other purchasers, the only draw back I found was that the standard queen pillow case is not large enough to cover the pillow well. It is comfortable and gives great support to your head and neck.
