Diamond Mattress Overview

Knowing more about the materials used and other product features, you’ll find out whether a Diamond mattress is the right choice for you. As hybrids, they suit most sleeper types, thanks to their consistent comfort and edge support. The company believes that improving sleep quality leads to a healthier and happier life, and they make their products according to that vision.

All the mattresses by Diamond come in three firmness options:

  • Plush, the softest option
  • Medium, the ideal firmness level for any sleeper
  • Firm, the best option for stomach sleepers

Stomach sleepers love the Transformation Firm for its spinal alignment feature, whereas side sleepers appreciate the Plush model’s supportive cradling feel created by its high-density foam. The Transformation Hybrid successfully eliminates pain in the hips, shoulders, and lower back due to its pressure distribution feature. Medium mattresses are the best option for all sleeping positions and body shapes, as most Diamond sleep mattress reviews agree.

Even though the bedding is slightly more expensive than the other brands, the Diamond mattresses won’t break the bank. And with the Forever Warranty, there is no doubt that the bedding is great value for money.

In addition to this, the brand sells bed bases, and other sleep accessories for improving sleep quality, such as essential oil diffusers, masks, and earplugs.

Diamond Pricing & Discounts

Diamond Mattress has been around for a while, and all the products are competitively priced. The Rally collection (both the foam and the hybrid) is the most budget-friendly option. While the most popular models — the Faith and Transformation Hybrid — are the costliest.

The prices depend on the size and type of mattress:

  • Transformation Hybrid: from $1,399 to $1,999
  • Intention Hybrid: from $899 to $1,499
  • Grateful Hybrid: from $699 to $1,999
  • Faith Hybrid: from $1,199 to $1,799
  • Rally Foam: from $799 to $1,299
  • Rally Hybrid: from $799 to $1,299

The prices range by size: Twin, Twin XL, Full, Queen, King, and Cal King for each collection.

The company offers continuous discounts and special offers on all the products, especially during the holidays.

Diamond produces a series of other merchandise, such as bedding collections, furniture, and sleep wellness items. You can get mattress protectors, sheets, bed foundations, and essential oil diffusers at an affordable price.

Shipping & Return Policies

The company ships the items to the continental U.S. Standard delivery is free, and Diamond Mattress user reviews mention it as a perfect deal. Any extra services such as white glove delivery are available for an additional fee.

For standard shipping, you can expect delivery within 3 to 7 business days. Delivery is carried out Monday through Friday, excluding holidays. You can get a shipping estimate before finalizing your purchase. According to Diamond Mattress user reviews, FedEx tracking information will automatically update the estimated delivery date, so you can easily see when your purchase will be delivered.

In case of a product return, the White Glove In-Home Delivery Service fee is non-refundable. However, you will still receive a full refund on your mattress.

Even though multiple products have a 20-year warranty, somehow, the company doesn’t cover products damaged by accident. Therefore, make sure you go through the instructions and warranty pages to see what exactly is included in the warranty.

Customer Service

Diamond Mattress Reviews and Testimonials

The company, with 80 years in the retail business, is known for finding new ways of customizing their products, researching customer demands, and following sleep wellness trends.

According to most Diamond Mattress reviews, the Diamond hybrids are a great choice whether you prefer the cradle of memory foam or the bounce of an innerspring mattress. The company’s long legacy is proof that it keeps up a great balance between quality, durability, and its products’ accessibility to customers.

Once you order the product and it arrives at your doorstep, the company offers you 120 days to change your mind. It is an extended trial period to decide if the mattress is comfortable and worth the money. Buyers mention it in Diamond sleep mattress reviews, and this policy results in a lot of satisfied lifelong customers.

The company spares no effort when it comes to the quality of the material and bedding components, using the best natural flame retardant, gel-infused foams, and right edge support technology. The Diamond mattresses’ comfort layer and the cover’s fabric provide exceptional body contouring, allowing a comfortable night’s sleep in any position. However, there are mixed comments when it comes to durability and support for various body weights. The heavier customers agree that the support wears out with time.

Alternatives

Diamond Mattress vs Casper

Casper prices range from $395 to $2,995, which is less than a Diamond Mattress. However, customers have a few negative comments about the feel of the mattress. The product is also less durable for heavier-built buyers. A strong point is that Casper has better-rated edge support, but it cannot be compared with the Diamond mattresses’ durability.

Diamond Mattress vs DreamCloud

When it comes to price, DreamCloud ranges from $799 to $1,599, which makes it more affordable than a Diamond mattress. The DreamCloud has better support for the spine as well and a 365-night trial period. However, the company has only one firmness level, which is bad news for sleepers preferring firm support or lush bedding. The stay-put technology will ensure you will not feel your partner moving during the night, and it is much lighter in weight. However, if you prefer locally made products, Diamond Mattress is the better choice for you.

Wrap-Up

The Diamond mattresses are a perfect choice for customers looking for a trustworthy hybrid mattress, an ideal blend of memory foam cushioning, and the bounce of innerspring coils.

The company handcrafts its mattresses. It manufactures everything, including the pocket coils, and sews the fabric. Apart from guaranteeing lifelong quality, the in-house manufacturing process allows the company to sell its mattresses and accessories at competitive prices.

According to the Diamond Mattress reviews, the material used and its level of comfort are the best features of these products. There are mixed reviews about the edge support and weight distribution in general, most probably due to customers preferring firm support over memory foam.

As all the products come with a Forever Warranty, the company guarantees the Diamond bed’s construction, materials, quality, and durability when bought from the original purchaser. Ultimately, even though some of the models are more expensive, their Forever Warranty makes even the higher-end models worth every dime.
