Handcrafted and family owned in America, Diamond Mattress provides quality comfort and support at an unbeatable price. Their three different collections cater to different sleep needs, price points, and construction preferences, making Diamond Mattress suitable for almost every sleeper.

Pick Diamond Mattress if...

  • You're looking for affordable quality. Diamond mattress provides innovative sleep technology and supreme comfort at prices that won't break the bank. If you're on a budget but you don't want to skimp on quality, Diamond Mattress is a great choice.
  • You like variety. Diamond Mattress features three different collections which target different sleep needs and preferences. No matter what your sleep style is, Diamond Mattress has something for you.
  • You're a high-performing athlete. If your body needs extra recovery time and pressure relief to prepare for another high-intensity day, Diamond Mattress has a model collection specifically designed for you. Opt for the Rally Collection if you're an athlete looking for regenerative sleep.

Seek alternatives to Diamond Mattress if...

  • You don't like the bed-in-a-box concept. While not all of Diamond Mattress's models are delivered in a box, the models available for purchase online are shipped this way. If you're uncomfortable with this shipping method, Diamond Mattress might not be a great choice.
  • You're looking for a traditional innerspring. Currently, Diamond Mattress doesn't offer innerspring models. If this is what you're looking for, consider the Saatva Classic mattress. It's a luxury hybrid innerspring mattress that sleeps incredibly cool and has built-in lumbar support to keep your spine aligned all night long.


Diamond Mattress has three different firmness levels to choose from to cater to different preferences and needs: Plush, Medium, and Firm.

  • Plush: This firmness level is optimal for side and combination sleepers looking for shoulder and hip pressure relief. If you like superior cushioning and feeling more "in" your mattress than "on" it, plush caters to this preference.
  • Medium: This is a medium firmness level ideal for all sleep styles, including back and stomach sleepers. Medium provides the cushioning you crave with the support you need for healthy spine alignment.
  • Firm: Firm is best for back and stomach sleepers who still want a mattress that provides adequate give and responsiveness.

Construction & Design

  • Diamond Mattress models are 12" to 14" high.
  • Diamond Mattress provides foam and innerspring models.
  • GIFT Collection: This collection provides luxury at DIamond Mattress's most affordable price. The patented system of individually wrapped pocket coils provide superior support and pressure relief, while the copper-infused foam keeps you cool while you sleep.
  • Rally Collection: Available in an all-foam or hybrid model, the Rally Collection is engineered to give athletes what they need while they sleep. The CoolTouch advanced cover works together with cooling foams that regulate your temperature. Gel and high density memory foam layers provide ultimate comfort and support.
  • Dreamstage Collection: Offered by exclusive retailers, the Dreamstage collection features nested coils, customizable memory foam layers, and a plethora of original styles to choose from. If you want personalized comfort, the Dreamstage is for you.

Motion Isolation

Almost all of Diamond Mattress's feature a specialized coil system specifically designed to eliminate motion transfer while providing targeted support. It's safe to say that due to Diamond Mattress's speciality in hybrid models, these mattresses are great for couples or for those who toss and turn.

Edge Support

Almost every Diamond Mattress model features a foam encased comfort edge to maximize usable sleep surface and decrease motion transfer further. This system makes Diamond Mattress a top choice for edge support.

Bed Frame Compatibility

Diamond mattresses are compatible with any bed frame, so long as the frame is the correct size for the mattress.


All Diamond Mattresses ship free in the continental US, and come with an 120 night sleep trial so you can make sure you've made the right choice. Diamond Mattress has a unique Forever Warranty, which protects the mattress for as long as you own it.

Why Buy Diamond Mattress?

  • You want to sleep cool. All of Diamond Mattress's models feature brand unique sleep technology, like the CoolTouch advanced cooling cover, or the Aqua Cool foam treatment. If you need a mattress that keeps you cool while you sleep, Diamond Mattress is a great choice.
  • You don't plan on purchasing another mattress for a long time. All of Diamond Mattress's models are protected by a Forever Warranty that lasts as long as you have the mattress. If you really don't want to buy another mattress after this purchase, then Diamond Mattress is a smart investment.
  • You want custom comfort. The Dreamstage collection allows you to customize firmness, materials, and construction to your sleep preferences. If you're looking for a mattress tailored to your specific sleep needs, Diamond Mattress's Dreamstage collection delivers.

Why Avoid Diamond Mattress?

  • You want a classic memory foam mattress. Diamond Mattress has many different models, but only one of them is all foam. While this all-foam model is a high-performing mattress, it won't deliver that classic "sink-in" feeling you want from a memory foam mattress. Instead, consider the Loom & Leaf by Saatva. This memory foam mattress cradles your body and provides a luxurious sleeping experience.
  • You want to shop from more than 3 firmnesses. While many people are satisfied with three firmnesses to choose from, this may not be a wide enough comfort range for everyone. If you like your mattress ultra plush or extra firm, Diamond Mattress might not be the right fit.

Final Takeaway

Diamond Mattress is a superior brand if you want affordable quality. Their mattresses are also surprisingly comfortable. You can get Diamond Mattress at discounted prices, today!
