We picked the 10 best mattresses using real tests & research to help you live a happier, healthier life!

Editor's Note

Diamond is a mattress brand & manufacturer.

There are 2 reasons why we do not recommend them.

  • Their purchase process is arguably more difficult (vs. top online brands - like Saatva.com or Puffy)
  • They have a less favorable (a) trial, return, exchange & warranty policies.


There are 3 better alternatives in our strong (+ well-researched) opinion.

  1. Saatva Classic: Check them out if you like a luxury innerspring hybrid feel.
  2. Loom & Leaf: If you enjoy durable memory foam that's built to last, see Loom & Leaf.
  3. Zenhaven: If you want to explore an incredible latex option (that's flippable), Zenhaven is unquestionably our top pick.


We consider these 3 mattresses better alternatives to Diamond because they have:

  • A seamless purchase experience.
  • Incredible comfort & material quality + a strong price-to-performance proposition.
  • Fantastic policies & customer service.

Why Pocket Coils?

Comfort, feel & firmness are extremely subjective and virtually impossible to comprehensively cover.

It's important to understand that buying a new mattress is one of the most critical purchases you can make in your life. It's really that impactful.

Sadly, buying a mattress is usually a blind purchase. This is because most consumers don't understand what makes a high-quality mattress. Even worse, it's difficult (and sometimes virtually impossible) to easily compare specs or decipher confusing claims (and conflicting information).

As a result, most mattress salespeople know almost nothing about the quality of the materials used in mattresses. They're taught to present stories and marketing techniques instead of specific, accurate facts that allow consumers to make better comparisons. Diamond is a brand that appears to be relatively comfortable mattress given what (1) our subjective testing has shown and (2) extensive reviews we've analyzed online.

The only true method to test comfort, feel & firmness is by physically laying on a Diamond mattress (in the privacy of your own home).

Spring vs. Foam vs. Latex - Which Is Best For Me?

The key to buying a premium quality/value mattress is knowing that each layer of the mattress uses high-quality materials.

These premium materials must be appropriate for both your budget and weight/BMI range.

Even low-quality materials can be very comfortable in a controlled showroom atmosphere (so you can't 'feel' their quality or durability). Don't be fooled by this. Cross off any trips to your local showroom. It'll lead down a long, frustrating road.

However, Diamond mattresses are seemingly well-built given the (1) specifications we reviewed (both on their site and speaking directly to them) + (2) our lengthy analysis of additional online reviews & feedback.

Motion Isolation For diamond mattress

Support & Motion Isolation For diamond mattress

Support and motion isolation are 2 distinct but closely related characteristics of a mattress.

Support refers to how well a Diamond mattress can accommodate your sensitive pressure points.

Motion isolation describes how easily you or your partner are disturbed by movement when laying on a Diamond mattress.

Everyone 'must' care about mattress support. There's no middle-ground.

Motion isolation, on the other hand, is more preferential. Motion transfer depends on how easily you & your partner become disturbed by small or large movements at night. Diamond mattresses are built well (since they’re also their own manufacturer), so support is adequate.

Some mattress types are better than others for support & isolation.

  • Innerspring: Good support. Poor motion isolation.
  • Memory Foam: Great support. Great motion isolation.
  • Latex: Great support. Good motion isolation.


It may seem like a no-brainer to ‘always’ select memory foam - since it's both great support and have great motion isolation.

But not always. Some people simply dislike the 'feel' memory foam has on their pressure points. Moreover, people might love innerspring ‘bounciness' or latex ‘weightlessness'.

Return Policy For diamond mattress

Diamond has a 120-night return & trial period to test their mattress.

Since Diamond is both a retailer & manufacturer, their policies are likely not on-par vs. alternative top online brands.

Additionally, each retailer that sells Diamond has their own unique policies that change between retailers. One retailer may offer a somewhat friendly return policy, while another might have a hefty penalty in the event of a return.

Separately, Diamond has several reports of relatively poor customer service, which is a testament to their potential lack of focus and transparency with their policies and service (compared to online brands).

This shortcoming is fairly standard with brands that also manufacture their product (but not always). Their overhead costs are usually much higher than strict online brands - which in-turn forces them to cut corners in order to understandably focus on areas they specialize in; manufacturing mattresses.

Diamond's warranty is difficult to find on their site.

We recommend calling or checking their site directly to confirm specific details.

In general, we recommend brands that have at least a 10-15 year warranty that completely cover any potential defects.

We also recommend a brand that doesn’t hassle you to measure body impressions to determine if you have a warranty issue. Visual evidence should be enough to determine if there’s legitimate sagging or not (at least in most cases).

How much does diamond mattress cost?

Similar to Diamond's warranty, their pricing is likely subject to change (quite frequently).

We consider these 3 mattresses better alternatives to Diamond because they have:

  • A seamless purchase experience.
  • Incredible comfort & material quality + a strong price-to-performance proposition.
  • Fantastic policies & customer service.

Diamond builds & sells mattresses.

They also offer several mattress types, including:

  • Gel memory foam
  • Latex
  • Pocketed coil
  • Hybrid

However, there’s 1 major problem with brands & manufacturers like Diamond (we don’t want to single them out).

Their policies are not as forgiving as other top online mattress brands (think Saatva or Puffy).

This is a bigger headache if (and likely when) you want to return, exchange or experience a warranty event. Their overhead costs is higher than online stores which likely negatively impacts their decision to have friendly, forgiving policies (more friendly = more costly).

Our Diamond review is not meant to make specific claims about how we 'think' you’ll feel on the mattress. Our only goal is to make sure you have all the available information you need to make an informed decision.

‘Mattress comfort’ is personal preference that wildly changes between 2 people (you’d be surprised by how much it does differ). The only true method to test the comfort & feel of a mattress is - you guessed it - in your bedroom. By extension, you want to select a brand that has friendly policies (i.e. trial period, return, exchange & warranty policy, etc) to best accommodate your ‘test’ period.

Based on the above facts, we don't comfortably recommend a Diamond mattress.

Before you make a final buying decision, take a look at Saatva Classic's model. They're our #1 Best Mattress (out of the 397 brands we analyzed).

We believe Saatva is likely the closest premium ultra-luxury alternative (specifically their quality of materials, warranty & customer service, and price-to-performance) that you'll find both online or in stores.
