The Sleep Science 9” Natural Latex is truly natural. This luxurious latex mattress has been developed for those that seek a more natural sleeping environment. This mattress is comprised of 2 layers of natural latex. The top 3 inches has been crafted to create a soft initial feel with the slight bounce of latex. The next 6 inches of natural latex is made to offer optimal support, while still allowing for comfortable conformity to the body. Natural latex is derived from the rubber tree and is transformed into the most durable sleep surface available on the market today. These latex layers are made using the Talalay method to create a durable, pressure relieving sleep surface. This natural latex mattress is resilient, supportive and conforming. The breathability of natural latex is unrivaled and keeps the body warmer in the winter and cooler in the summer. The feel of latex is plush, yet offers instantaneous recovery and support. The mattress cover is made of 37% organic cotton and the fire retardant properties are chemical free. The mattress cover is quilted using wool and an inherent fire retardant fiber in order to pass the stringent 1633 and 1632 Fire retardant certifications.

Customer Reviews for Sleep Science 9" Natural Latex King Mattress with Foundation
Review 1 for Sleep Science 9" Natural Latex King Mattress with Foundation
Date:July 12, 2014
Review After 1 Year
Pros: support, resiliancy, inner-spring like bounce
"I wanted to give us a long window prior to reviewing. We've had several inner-spring mattresses and while all were comfortable, over time they develop large depressions and the comfort level declines until replaced. Between memory foam and Latex, we went the latter route since we wanted cooler sleeping (latex breathes better). We also wanted the near immediate bounce-back of latex.
I'm 200 lbs and 6' 5", and find the mattress perfect. I sleep better and wake up with more energy and less stiffness. My wife, 135 pounds and 5' 8", finds it very supportive but she added a soft mattress pad as it was initially a little firm for her. The mattress itself is very heavy and awkward, so plan on two strong adults to struggle moving it. We've noticed absolutely no depressions or wear, a full year in. All in all it's an expensive (though good deal for latex) mattress but one that we really like and look forward to many years of use."

Review 2 for Sleep Science 9" Natural Latex King Mattress with Foundation
Date:January 25, 2014
Lasts for 20 years?
Pros: few short hours of strong latex smell then nothing
Cons: not for side sleepers
Model Number: Sleep Science 9" Natural Latex King Mattress with Foundation
"I'm a side sleeper. I did my homework speaking with one of the owners at the manufacturer's business in Cali - direct questions posed about impact on cotton and latex for side sleepers.
The owner ASSURED me this would not breakdown before the 20 year life expectancy had come and gone.
Two short months later, my back is killing me!!! Wouldn't you know it - a sag has developed at the same location of the bed where my hip rests...SURPRISE!!!
Recently placed a call to same owner who was reportedly out of town that day. I called back again (different employee than first call) - I went thru the explanation and issue and learned this person had exact same bed, also a side sleeper, and exact same problem developed within a few months!
Employee advised they opted for Sleep Science's Black Diamond bed and it is working out just fine/has held up for lengthy time now.
It's been two weeks and still no response from owner.
Thank God for Costco return policy - I'm returning bed to Costco"

Review 3 for Sleep Science 9" Natural Latex King Mattress with Foundation
Date:June 27, 2013
Pros: firm but comfy, a "green" matress.
"We ordered the bed despite no reviews and were quite nervous but then figured we had nothing to loose with Costco's return policy. The bed arrived in 3 weeks and did have a smell but that was excepted. By the time we went to bed at night the smell was pretty much all gone. The bed is firm. I am struggling not having the cushy feeling but my husband loves it. He no longer has back pain and I no longer have pressure point issues which is amazing. I did have issues with my arms falling asleep for a week but I read that it can be normal when adjusting to firm beds. We have had the bed for 2 weeks now and so far we are super happy."
