Diamond Hybrid Mattress Reviews in 2024


Without much ado! Let’s find out more about the Diamond Grateful Mattress.


The Diamond Grateful bed is not only the most popular but as well as the most affordable mattress from Diamond. Despite being cheap, this doesn’t imply that the bed is made of cheap materials. On the contrary, Diamond Grateful Mattress features quality memory foam and pocketed coils in its layers.

On top of the mattress is the quilted cover that allows free airflow. As a result, the sleeper sleeps cool. Next is the cooling gel-infused memory foam layer. The high-density transitional foam layer follows the comfort memory foam layer. Finally, we have the zoned pocketed coil layer, which supports the sleepers’ weight and makes the bed breathable.

All these layers make up a thickness of 10-inches. This is the same thickness that the other Diamond Hybrid beds have. The layers offer support and comfort to the user, while the cooling gel memory foam and top quilted cover make the mattress breathable and sleep cool.


The biggest challenge of owning a Diamond Mattress is its durability. Many users disagree when it comes to the longevity of this bed, which raises many questions. Is the mattress durable? Can I buy it for long-term use or not? With such questions in mind, it is difficult to tell whether this mattress is reliable or not.

Considering the materials that the manufacturer has utilized in the bed’s construction, expect your mattress to last for at least 6 years. Nevertheless, several users have complained that the beds start to sag earlier and become uncomfortable.


In terms of hardness, you can never go wrong with Diamond Mattress. Diamond beds provide various firmness options. For instance, the Diamond Grateful bed has firm, medium-firm, and firm beds. The firm mattress has a score of 4, the medium-firm a score of 6, and the firm a score of 9. All of these are on the firmness scale of 1 to 10.

This indicates that there is a bed for every type of sleeper. Regardless of whether you sleep on your side, back, stomach, or combination sleeper, you will get a bed that meets your needs. The plush bed is ideal for lightweight and side sleepers. The medium-firm is suitable for everyone, while the firm mattress is perfect for heavyweight sleepers and stomach sleepers. Make sure you pick the right bed for your body and style of sleeping.

Pressure relief

This is one area where Diamond Mattress excels better than competitor hybrid beds. Diamond Mattresses provide excellent pressure relief. In particular, the Diamond Grateful bed features quality foam layers that conform to your body seamlessly. Specifically, the CoolTek gel-infused memory foam layer contours around your body to alleviate pressure and sleep soundly.

All the other Diamond Hybrid beds also offer pressure relief, with the Diamond Transformation bed being the most notable in this category.

Motion isolation

Even though the Diamond Mattresses may not provide the same motion isolation level as all-foam beds, they do an excellent job. The top foam layers found on Diamond’s Grateful Mattress help to absorb as much motion as possible when bearing weight. This results in the bed transferring little motion to their companion.

If you’re looking for the best Diamond Mattress for isolating motion, you will have to consider the Diamond Transformation bed. This mattress has a special micro-coil technology layer that does a fantastic job of isolating motion.

Edge support

If you decide to get one of the Diamond Hybrid beds, you can forget about sinking edge support. All of the Diamonds models, apart from the Rally Foam Mattress, features a reinforced edge. This means that side sleepers won’t sink in any of the beds when you sleep or sit on the mattress’ side.

Temperature neutrality

Sleeping cool is vital for a peaceful night’s sleep. Diamond Mattress makes sure that all their sleepers sleep cool, regardless of the bed that they choose. Diamond Mattresses feature a cooling gel memory foam layer. Moreover, most of them have a breathable cover that wicks away heat.

The Diamond Grateful bed cooling gel-infused memory foam layer, quilted top cover, and zoned pocketed coils. All of these help in the bed sleeping cool. Hot sleepers will love this bed to a great extent.


All the Diamond’s Hybrid Mattresses are fantastic when it comes to sex. Hybrid beds are excellent for sex because of their bouncy and responsive nature. The Diamond Grateful bed is bouncy and very responsive. This means that couples can change positions easily on the bed as they won’t feel stuck in the mattress. What’s more, the bouncy nature of innerspring beds makes sex enjoyable and fun.


If you want a virtually silent Diamond Mattress, you will have to consider the Diamond Rally Foam bed. As stated earlier, Rally has an all-foam bed and a hybrid bed. The Rally Foam bed is made purely of foam layers. As a result, the bed is silent as there are no coils to make squeaks or screeches. Hence, the sleeper can take a nap without being distracted when they change in bed.

The Diamond Grateful bed comes with coils in its structure, which means you may hear some noises as you jump or have fun.


Diamond Mattress makes quality beds using quality materials. For instance, the foam layers used in the construction of Grateful Mattress are CertiPUR-US certified. This means they are free of chemicals and dangerous metals.

The mattress comes in a box and people have complained about some smells after unboxing the beds. However, the manufacturer assures buyers that the odor is not dangerous as no chemicals are used in the beds’ construction. The smell may dissipate after 24 hours. Have the windows open and sleep on the bed when the odor disappears.

Trial period

Many online mattress brands are offering a free trial period as most of them don’t have showrooms. Diamond Mattress is one of them, and it provides its customers with a 120-night free trial period. This is enough time to discover if the bed is okay or not. The manufacturer also recommends buyers test the mattresses for at least 30 to 60 nights before returning. They don’t have a mandatory break-in period before returning the bed anytime within the 120 days.


The company provides free shipping to customers within the contiguous US. If you live in Alaska or Hawaii, they will still deliver your bed but at a certain fee. Furthermore, they provide white glove delivery at a charge. Note that white glove delivery is not refundable if you decide to return the bed.


Diamond Mattresses are very affordable when compared to competitor mattresses in the market. The main reason behind this is that they don’t sell their beds throughout third-party, and there are no middlemen.


The manufacturer offers the best guarantee on the market – the forever warranty. As long as you don’t transfer the bed’s ownership, the original user will be covered for a lifetime.

Intention Mattress

The Intention mattress is another affordable bed that appeals to sleepers looking for great value for their money. Additionally, it is a hybrid bed that provides consistent comfort and support to the user. The bed is a mixture of high-quality memory foam and innerspring coils. It has three firmness options, which give all types of sleepers the option of choosing the best bed for their needs.

The bed is made of a cool-touch temperature regulating cover, an excellent egg-crate foam layer, a transitional layer, and a support pocketed coil layer.

The top cover is breathable and wicks away heat, while the egg-crate foam layer conforms to the sleeper’s body for added comfort and pressure relief. On the other hand, the transition layer prevents sinking into the bed, and the pocketed coils make the bed bouncy and breathable.

With these exceptional features, hot sleepers will find this bed to be a great choice. It has a thickness of 10-inches with three firmness options: Plush, medium-firm, and firm mattresses. Overall, this bed might feel softer than the Grateful Mattress.

Faith Mattress

Faith Mattress has the same features as the Diamond Intentions, but it is somehow advanced. The difference between these two beds is that the Diamond Faith bed has advanced cooling features. Like Diamond Grateful bed, this mattress comes with three firmness options, ideal for different sleepers.

Diamond Faith bed is costlier than Grateful and Intentions bed. Also, the firmness ratings vary from 2 to 8 on the firmness scale of 1 to 10, which considers all sleepers’ comfort. Nonetheless, there have been worries about the durability of the bed.



Transformation Mattress

The Diamond Transformation model is the most advanced Diamond bed. This mattress is uniquely constructed with micro-coil technology, which assists the body to adapt seamlessly. The bed is also super comfortable. It boasts an advanced cool-touch cover, conducive memory foam, micro coil matrix, transitional high-density foam, and a base of pocketed coil matrix. All of these layers make up a comfortable and supportive bed.

With a thickness of 10-inches, this bed has the same thickness as the Diamond Hybrid beds that we’ve looked at. Nonetheless, the mattress has three firmness: plush (3), medium (5), and firm (8). The unique micro-coil layer consists of more than 1000 micro-coils, which increase airflow and reduce motion isolation. Moreover, they help to relieve pressure and make the bed comfortable to rest on.

All-in-all, the Diamond Transformation bed is Diamond’s premium bed. It is costly but worth every coin spent on it.



Rally Mattress

If you want an all-foam bed or customize your bed, choose from Diamond Rally Mattress line.
