My husband and I had a 2 year old mattress that just wasn't cutting it. Due to his back problems (bulging discs), he wanted to get a memory foam mattress to help alleviate the pain. We shopped around at furniture stores and such in San Antonio, and we were looking at MINIMUM $2500. So, I decided to look on overstock...and I am SO glad I did. I ordered the firm mattress because my husband and I both like a really firm mattress (I weigh 110, and my husband weighs about 240). The mattress came in five days, was 95% expanded within 10 minutes, and we didn't have a "smell" to our mattress. That is the BEST night's sleep I've had in a LONG time, and I didn't want to get up this morning. If you get firm, expect FIRM. It has very little give to it, which is exactly what we wanted/expected. However, it still conforms to your body to give you support. This is the first time in a long time that I remember dreaming. It really is a good buy and is worth the money!
