I was a bit skeptical about ordering a hybrid mattress by mail, but I am so happy I did. Ordering was easy, shipping was prompt, the mattress inflated quickly, and it provides a marvelously comfortable night's sleep. I ordered the firm because my back needs a lot of support. I would recommend this mattress to anyone. One caveat--as a reasonable fit middle-aged woman, I managed it alone, but it is heavy, and would be much easier to set up with two people. The handles on the box top and on the mattress helped a great deal.
Diamond customer service was so nice and helpful. They sent our new exchange relief medium plush mattress directly to us because the store we bought the defective mattress had closed their business. We have slept on our new mattress for 2 weeks and no sore body parts so far. We are hoping for the best. Thank you Diamond mattress!
Hi Mary, Thank you for your review. Please let us know how we could have made it five stars. Have a great day.
Hello, I have always had a Serta, we purchased the Intention FIRM, this is the most comfortable mattress I think I have ever had. At 53 my bones hurt more than they used to but on this mattress, I get a better night's sleep! Thank you Diamond Mattress. I am looking forward to sleeping at night now!
I have had only used Diamond Mattresses for the last 30 Year’s and I have not been disappointed once. They continue to deliver a great product. I am glad they are still around.
The comfort is what I expected, but the cooling is not what I expected. I sleep hot and I noticed after a few nights that I was not getting as hot when staying in one position for a long time. I feel a bit more rested when I get up in the morning, possibly because I'm not tossing and turning as much.
