    • Not as described

      I will try very hard to stay subjective. This mattress is not what they have described. It is very soft, and light weight. When I sit on it, my hip press the mattress all the way down until it hits the bed frame. I am 5 feet 10 inches 155lbs. The support it provides is like next to nothing. I had back pain after day one. I was lucky that I didnt threw my old mattress away. but even if I did, I will still chose the floor over this mattress.

    • Hard as a rock

      I have had this mattress for over 3 years. It is way too firm. I wake up every morning with a sore back and my arms numb. I have to sleep on my side to ease the pressure. I have tried memory foam toppers to ease the pain, but that only creates other back problems. I will try a latex topper before I give up and give it away.

    • Definitely Firm

      We received this mattress about 3 weeks ago and it fit perfectly into our Cal King frame (we put down plywood first). It was extremely firm. I immediately ordered a 1-inch memory foam topper from Overstock as suggested by another reviewer and now it is PERFECT! I do not want to get out of bed in the morning and I even woke up drooling once. I don't mind this set up as I'll be able to affordably replace the topper as needed in the future and the mattress itself seems like it will hold shape forever. I think a 1.5 inch topper might be even better but I wouldn't go as thick as 2-inch. Our bed is now firm but soft if that makes sense. I love it!

    • Great mattress!!!

      So my husband and I spent lots of $ on a name brand mattress over 10 years ago It was a pillow top and was supposed to be firm. It was never really firm and began to sag a few years back. I started researching for a new mattress and found this one on O and read all of the reviews and they sounded positive. On a whim, I ordered the mattress. In came in a relatively small box but once we opened it and let it expand, it was truly a Calif King size mattress. We've been sleeping on it for only a few nights now but I've noticed that I do not wake up with the usual back pain. I've also been sleeping through the night which I thought was due to insomnia but I wake up refreshed now. I think this was a good purchase but i'll update it anything changes.

    • Amazing!

      I waited to write a review until I was good and sure that I would be telling the truth. (We bought this bed in April of 2010.)This is the most amazing mattress I have ever had the pleasure of sleeping on. Yes, it's firm. When they say firm, they mean it. However, it's not like sleeping on bedrock. There is still enough "give" to conform to your body as a latex memory foam mattress should, yet it does not trap you in the bed as some have the reputation of doing. I do have a 1in memory foam pad on my side of the bed, and let me tell you....HEAVEN. I don't ever want to get out of bed. Ever.

    • Extra-Extra Firm - Needs an Additional Soft Topper

      THE PROCESS: Replacing our 15 year Spring Air (SA) "Four Seasons" cal-king mattress was a task my wife did not want me to undertake; however, I was beginning to have back pain, and a 100% latex mattress seemed to meet my needs, and the ECO our price point. Upon arrival, the UPS driver and I carried the box from his truck to our entry door. Unboxed, I rolled the mattress upstairs and placed it on top of our SA luxury wrapped steel box set. Unrolling the mattress from its plastic, I pulled the ever expanding roll back to bed center pushing each exposed layer of plastic underneath the mattress until it sprung open unfolding itself in 2 seconds (watch out) on the box set. QUALITY: No odor, the mattress has a good quality side zipper cover. So extremely firm, even the top 2" soft layer is virtually unnoticeable. After 2 weeks sleeping much cooler on the latex than on our SA wool cover, my wife, a back sleeper, said she was very happy; for me, a side sleeper, I found my back pain had slipped away, but I began to awake with my arm(s) asleep. Unable to find a cal-king latex topper at “O,” I found a 2” soft latex bamboo cover topper for $249 shipped out of AZ - try searching “latex bamboo topper”. We have slept happily since…100% latex for under $1000.

    • Best Mattress

      I refused to write this review until three years had gone by. My husband and I spent a decade trying to find a mattress that pleased us. We went through 3 expensive mattresses. The first developed a mountainous ridge between us and the next two that started out as very comfortable, developed body impressions that swallowed us whole. I began reading the reviews of the E.C.O. Latex firm mattresses months before we finally made the purchase. We purchased the 10" California King in the summer of 2010. We love this mattress! Yes, it is very firm and we had to adjust to that, but three years later and there are no significant body impressions. This mattress is a keeper and I can't imagine this mattress letting us down anytime soon. I hope if it ever needs to be replaced, that it will be with a mattress exactly like the E.C.O. that we currently own. Kudos to a great product and a good night's sleep!

    Questions & Answers

    Get your product questions answered right here.
    • What is the weight/density of the "8-inch polyurethane foam base"?

      • Hello Kay, the density is 1.8 pounds for the base foam. Thank you for shopping with us!

    • Has the interior foam been treated with fire-retardants?

      • Hello benlovesbear, this Latex Mattress has an FR Sock that protects the product. When the Fire Resistant part of the mattress is not part of the foam, by law, it has to be part of the fabric cover. We can tell you that the foam itself has no FR chemicals in its make up, BUT the fabric we have to use is FR and therefore has chemicals in it. Have a great day!

    • What is the ILD on the latex?

      • Thank you lynnakeime for the opportunity to help you with the Select Luxury E.C.O. Latex Firm 10-inch California King-size Mattress. The ILD rating is a 34-36, firm mattress. Thank you for shopping with us.

    • Does the mattress have a warranty?
