Diamond Mattress
The Faith mattress features Diamond's CoolTouch Advanced fabric, the most receptive temperature-regulating fabric in the market. This hyper conductive fabric responds to your body's temperature, changing color when absorbing heat and actively recalibrating your inner core to be exactly where it needs to be to fall asleep naturally.

Also built within the Faith mattress is Diamond's Hyper Conductive Sparkle Foam and Patented Support System, both contouring layers that adapt to your body's unique needs, so you can retreat to your ideal comfort zone every night and wake up ready to conquer new adventures. The Grateful mattress supports you perfectly using our signature dynamic edge coil system.

Love that this company is family owned and made locally in California. I am on my 2nd mattress from them and I love it!

I bought a diamond mattress “Faith Hybrid” I’m absolutely in love with it!! It is heavy.. but easy to set up! I’m a single gal and I used my dolly which helped. However, It’s extremely comfortable it’s perfect it feels like I’m sleeping on a cloud! Absolutely satisfied! I definitely recommend!

Diamond Mattress is a terrible mattress. I bought a Diamond Mattress from Living Spaces and after only a couple of months, I began to "sink" in the middle of the mattress and, as a result, I have a backache from this mattress every morning. I have tried contacting Diamond Mattress but they won't return my phone calls. I have filed a complaint with the Better Business Bureau about this mattress. I would never recommend to anyone that they buy a Diamond Mattress. If they had a "zero" star for this review, that's the star I would have chosen instead of "one" star.

I sleep on a Diamond mattress and have been for years. It's comfortable and has held up well. I've had other mattresses in the past which become firm and lumpy over time, and this one has held its shape and comfort. Long time family owned business. Highly recommend.

I bought a $1300 Medium Diamond mattress at Living Spaces a few months ago and it was the worst buy ever. A $200 ikea mattress is ten times more comfortable. The mattress is sinking unevenly throughout the surface of the mattress. I filed a complaint with the warranty and the technician came out to my house and measured the mattress by hanging a rope across. When he used his hand to push on the mattress, he concurred that it’s sinking unevenly with more depth in the middle than the outer edges. When the warranty called me back, I stated the issue, but they dropped the call and never called me

These beds are awesome. Anyone who disagrees has issues. The owners really care for their employees, and as a result, good-quality beds are made. Great customer service. Fair prices. Good people working there. Especially the whole Bed in the Box department. It’s amazing. Again, anyone who disagrees has issues :)

I bought a Diamond mattress from Living Spaces in January of 2017. By February of 2018 I noticed my side of the bed starting sinking in which caused me to start having severe back and neck pain. It felt like I was sleeping in a cereal bowl. I now have to scoot over to my wife’s side of the bed just to get some decent back and spine support. Horrible, horrible mattress. I got one year out of a mattress that cost me $1000! I just bought a temurpedic mattress today to replace the Diamond mattress. Yeah it cost a lot more but as the old saying goes, “you get what you pay for.” If you can afford

Do not buy this mattress if you are not used to foam mattresses. They have a zero return policy. We got ours through living spaces and were talked into a medium firmness hybrid mattress. I liked the plush in the store but the sales person suggested medium since I sleep on my back. The first night I got it I couldn’t sleep. Felt like sleeping on the floor. There are plenty of companies out there that offer a 30 day trial period. I would go with one of those.

I have tried for the last three months to exchange this mattress and even upgrade to a more expensive model. The customer service is horrible and this company cares little of it's product and not at all for the customers that shell out their hard earned money. I made a huge mistake in buying a Diamond Mattress. I'm out $1300 and have a mattress that is not only uncomfortable but now I'm having back pain. Don't make my mistake, don't buy Diamond.
