Tranquility Collection

The Tranquility by Diamond Mattress is a collection of four models: Cloud, Clarity, Waterfall, Balance. These are innerspring mattresses with foam comfort layers. All four models have latex in the comfort layers. Waterfall also has gel, and the other three have memory foam. Diamond Mattress claims its Tranquility models have "natural" materials. It's Eco-Flex foams use plant-based ingredients.

Mattresses in the Tranquility Collection are rated as "highly conformable." This conformability begins with the innerspring. It is made of individually wrapped pocket coils (a.k.a. Marshall coils). Their independent responses conform to body contours to lessen pressure and promote proper spinal alignment. Pocket coils also eliminate motion transfer, so when one sleeper movers, the other one is not disturbed.

The three principal materials found in the comfort layers of Tranquility mattresses are latex, memory foam, and gel. The latex is natural Talaly latex, made from the sap of the Brasilian rubber tree. Latex is reslilient, quickly recovering its original shape when weight is removed.

The memory foam contains soy-oil. Memory foam is conformable. For a brief time, it remembers the shape of the weight pressed on it.

Gel is supportive and cooling. It is infused into mattress foam for those reasons.

Models

At 15", Cloud, a super pillow top, is the highest model. It is also the softest, with a firmness rating of 2 on a scale of 10. Its comfort layers are latex foam and memory foam. According to Diamond, it and Waterfall are the best selling models in this collection.

Clarity is the second highest Diamond Mattress Tranquility model. It is a 14" high pillowtop mattress rated as luxury-plush (3 on the scale). Its comfort layers are latex and memory foam.

The next highest model is the 13" Waterfall, a medium-plush (5) eurotop mattress. Its first comfort layer is latex, and the top layer is gel (or gel foam). Waterfall is one of the two more popular Tranquility models.

The lightest model in the Tranquility Collection is the 12" Balance. It is a tight top mattresses with a luxury-firm (8) comfort level. Its pocket coil innerspring is topped by layers of latex and memory foam.

Tranquility Collection models are compatible with adjustable foundations. Diamond Mattress sells two Leggett & Platt adjustable bases: S-Cape Lifestyle Base and Pro-Motion Lifestyle Base.

Tranquility mattresses carry a Diamond Mattress 20-year warranty. They are available in stores in southern California.

I have owned the Ethos – Tranquility Luxury Medium Mattress (Approx. value $2800). Have been very satisfied with the mattress for around 3-4 years. Even though I have owned this mattress since October of 2014. The mattress was delivered to my Southern California residence in Santa Clarita. During the 1st year of purchase. I have only slept on this mattress once or twice for every 60 to 90 day period, It was not until September of 2015, when I have fully moved back from my Northern California address did I sleep on this mattress on a daily basis. So I have really had a good 3-4 year comfort experience before the mattress started to show the deformity. This deformity has resulted in not being able to sleep on my side of the bed due to the sagging of 1 ½ to 2 ½ inches over approximately 25% of the mattress. This uneven sagging is observable without the need for anyone to sit or even lean on the mattress. About 4 weeks ago I have contacted the reseller from whom I have purchased this mattress and was given the manufacturer contact information. I contacted Diamond Mattress and was required to submit photos and fax over a warranty claim form. Diamond required to send over an inspector to document and process the warranty claim. Diamond Inspector showed up on April 10, 2019 and took more photos and was able to determine that the deformity maybe corrected by replacing the broken bed foundation. The bed foundation was purchased along with the mattress as supplied from the reseller which happens to be original Diamond Mattress foundation. Additionally, when inspecting the mattress the Diamond inspector was able to expose 8-10 inch tear in the mattress stitching (not related to the foundation issue) which was only observable upon turning the mattress bottom up. The inspector said that Diamond Mattress will contact us within a week. On April 18, we heard back from Diamond and were told that even though the warranty would cover the mattress for 10 years, the mattress foundation would not be covered? Asked about the tear in the mattress and he said something along the lines “we should have reported this issue upon purchase”? I am speechless as to the lack of common sense of that statement with which the Diamond representative insulted our intelligence. How can the Diamond representative assert that the tear in the mattress was already there upon the time the mattress was purchased and delivered? And assuming that was correct, where is the quality control in releasing and shipping a defective mattress and foundation to a consumer? And how many consumers are likely to flip the mattress on its back looking for such a defect? The mattress warranty states that it may be void if the wrong type of foundation is used. However, even when Diamond has supplied their own foundation, Diamond Mattress would not honor their warranty. My experience has demonstrated that Diamond Mattress Warranty is a lie. Diamond should have stood by their product and I should have been provided with a non-defective foundation for this expensive mattress set. The value of this mattress set to me is less than$1000. Effectively, when I have purchased the Diamond Mattress product, I have wasted close to $1000. (after applying discount value)
