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.
