Typically, we have a 30-60 day acclimation period . This product was an excellent choice with no "break in" period or any discomfort from the start. We are very pleased with our choice. It is now very difficult to get out of bed on these cold winter morning here in Minnesota!!!! And movement by either of us does not disturb the other. Motionless!!! Awesome.

[This review was collected as part of a promotion.] This mattress saves my life. After traveling all over the world for work, coming home to my new bed has never felt so good. It gives me a complete refresh of spirit and I can't wait to enjoy it for years to come!

Mattress is sagging! They allow a form on line take pictures of receipt, take pictures of the bed and last turn your mattress over and take a picture of a tag! We are elderly it's hard. The store we bought it from doesn't help! They don't carry the warranty! Great! It's only 4 years old and it's sagging at the bottom of the bed. After 3 calls to warranty a nice women suggest we get a mail in warranty not on line because the pictures I took on my phone I didn't know how to make them smaller ! So frustrating

Not as great as everyone says it is. I was very excited for the cooling feature because I sweat a lot at night and after the first night with this mattress, I've never sweated more in my life. And it's been multiple night, still have yet to notice the cooling feature. Very disappointed that this is non existent..:

I have had this a week now and really hope it will get softer over time. I came from a sealy I series in medium that was too soft so I went with the firm in Tempur-Pedic. It is way too firm. Time will tell but right now not happy with the back aches I have every morning. A lot of money of for something I cannot use.

When looking to upgrade from an older model, I was torn between going medium or a new spring mattress. The hybrid offers the best of both worlds wrapped in Tempur-Pesci' s high quality brand. I can't recommend this model enough to people on the fence between joining the Tempur-pedic family.

[This review was collected as part of a promotion.] We have owned Tempur-Pedic mattress for over 20 years, and yes, they last forever. It was time for a new one, and we went with the soft at first, and it was just too soft. We exchanged it for a firm, and it's perfect. I have hip and back issues, and can only sleep on my side if there is no resistance against my joints. Would definitely recommend this mattress.

[This review was collected as part of a promotion.] Split King with adjustable base: Excellent comfort whether sleeping, reading, watching TV, etc. Definitely worth spending the extra to get the Ergo Extend Adjustable Base so that when you adjust to a more upright position neither you or your mattress slide down toward the foot of the bed. And the mattress does not sleep "hot". (We had the original Tempurpedic mattress for many years and loved it, but decided to upgrade to the adjustable series, which is excellent.)

This mattress is comfortable and is almost firm enough for us. What brings it down from an A is we know that after 5-10 years this mattress that is already not firm enough will be even softer and uncomfortable. We were told this is the most firm mattress sold by Tempurpedic. :(

I never knew sleeping can be this good. With this mattress i sleep fast peacefully and when i wake up i feel refreshed after a comfortable amazing sleep. Also its a therapy for back issues. Me and my husband both have bak issues and now its improving. I love this mattress
