  • Firm comfortable mattress

    I waited a few weeks after receiving the mattress to review. Although the mattress was firmer than I had expected, I prefer a firm mattress, so this is fine with us. The odor that is common to these memory foam type mattresses took a couple of days to dissipate. We have absolutely no complaints about the mattress. My back pain that I was waking up with in the morning previous to purchasing this mattress has much improved. I would definitely purchase this mattress again and I do recommend it for others.

  • It's a nap magnet!

    Something about that bed makes it nearly impossible to walk by without grabbing a quick cat nap! I fall asleep immediately. Not to mention a great night's rest. I purchased the latex bed because of chronic hip pain at night. My pain has diminished greatly. The organic cotton cover came with a tear in it and the customer service team at O has been great about getting me a new replacement. The price is amazing compared to the you-know-what beds. And every bit as comfortable and quality made. I figure I saved many hundreds of dollars. Thanks again O!

  • Orthopedic 12-inch California King-size 4-layer Me

    excellent, no odor, self inflated in a matter of an hour or so. Well wrapped and we are very pleased. After sleeping on an air matress for 15 years, my bad back is finally getting some relief. Only problem is after purchase, they raised the price on it $$$+ dollars.

  • The Absolute Best!

    This mattress is wonderful. My husband had many issues with pain & hasn't been able to sleep in the bed for years. This mattress has fixed that. Now it seems I can't get him out of bed. Well worth the price. No smell. Convenient washable cover. I love it.

  • Firm, comfortable mattress

    I paid more than twice as much 9 years ago for a memory foam/latex mattress from a high end furniture store which pales in comparison to this mattress. It's firm but I still feel like it gently conforms to my body. Arrived in two days in a very compressed package but opened up to full thickness in less than two hours. Well worth the price.
