Key Similarities:

  • All three of these mattresses are phenomenal picks for side sleepers thanks to the pressure-relieving materials used in each. Our testers loved the Casper and Nectar so much that they added them to the list of best mattresses for side sleepers.
  • As far as sleep trials and warranties go, all three mattresses offer generous policies. The Casper and Purple come with a 100-night sleep trial and a 10-year warranty, while the Nectar offers a full-year trial and forever warranty for as long as you own the mattress.
  • Durability and quality is guaranteed with all of these mattresses. Each uses high-quality foams and materials to construct premium mattresses built to last.

Key Differences:

  • The Nectar is the most budget-friendly option, while the Casper and Purple are more similar in price.
  • The Casper and Nectar are both memory foam mattresses, and the Purple is a hybrid mattress. Although the Casper and Nectar are both foam mattresses, they still use different materials. The Nectar uses gel-infused foam layers while the Casper is your classic memory foam bed through and through.
  • The Purple is the only mattress out of the three that’s suited for hot sleepers. The Casper and Nectar don’t do as good of a job keeping you cool because of their all-foam design.

The Nectar Mattress

  • I could go on about the Nectar mattress for days, but for the sake of time I’ll break down some of the best things about this memory foam standout. Nectar gives you some of the best value in the mattress space; you can get a queen size for well under $1,000. It’s no wonder we named it one of the best budget mattresses.
  • The gel memory foam layer provides some of the best pressure relief around. The foam cradles your hips and shoulders so you feel cushioned from head to toe.
  • It’s no surprise that Nectar has an overwhelmingly satisfied customer base—less than 3% of customers end up returning their mattress. The lifetime warranty and full-year sleep trial guarantee the Nectar’s outstanding quality.

Best For:

✅ Shoppers on a budget

✅ Side sleepers

✅ Memory foam lovers and those who like to be cradled by their mattress

        ✅ Couples and those who sleep with a pet

Not Best For:

❌ People who prefer the feeling of sleep on an elevated surface

❌ Heavyweight sleepers

        ❌ Hot sleepers

        ❌ Combination sleepers (those who toss and turn throughout the night)

Purple Mattress Review Highlights

  • The Purple mattress features a unique Purple Grid layer that uses pressure-relieving material to cushion sensitive areas and keep the spine aligned. Because the Purple excels at pressure relief and spine alignment, it’s a great pick for side and back sleepers
  • Hybrid mattresses often combine the best of both worlds and the Purple is no exception. The Purple is one of the top-rated hybrid mattresses and keeps you much cooler than an all-foam mattress would. The breathable cover increases airflow for maximum cooling.
  • Known as one of the best mattresses for athletes, the Purple does a great job at relieving sore muscles and pressure points so you can wake up feeling restored after even the most intense of workouts.
  • Customers who own Purple say it’s transformed their sleep by relieving neck and back pain.

Best For:

✅ Those who suffer from back pain

✅ Athletes; those who are active

✅ Hot sleepers

        ✅ Back and side sleepers

Not Best For:

❌ Couples

❌ Combination sleepers

❌ Those who prefer a traditional memory foam or traditional innerspring mattress

Casper Mattress Review Highlights

  • The Casper mattress is what memory foam dreams are made of. With 4 thick foam layers and a medium-firmness level, the Casper offers a universal fit suited for all sleep positions.
  • The original Casper offers Zoned Support—an innovative foam construction that contours to your pressure points, providing relief and support where you need it the most.
  • Our testers gave the Casper a perfect score on responsiveness, so listen up combination sleepers! This is the bed for you. We loved how the Casper did an excellent job of responding and adapting to our movements.

Best For:

✅ All sleep positions

✅ Those who prefer the classic memory foam feel

✅ Sleepers of average weight and size

Not Best For:

❌ People who prefer a traditional innerspring mattress

❌ People who prefer firm mattresses

❌ Those who sleep hot

Nectar mattress construction

Inside the Nectar Mattress

With three soft foam layers that work to limit motion transfer, maintain an even sleep surface, and support and conform to your frame, the Nectar covers all of the bases.

  1. Quilted memory foam cover: Soft top layer that promotes air circulation and is bed bug resistant.
  2. Gel Memory Foam: Comfort layer that evenly distributes body weight and heat to keep you cool while gently contouring to your curves.
  3. Adaptive Hi-Core Memory Foam: Supports your body in all the right places and prevents sinking into the mattress.
  4. Base Layer: Polyfoam foundation that provides stability and structure to the foam layers and reinforces support for the entire mattress.
  5. Bottom Mattress Cover: Keeps the mattress in place to prevent any slippage issues.
Inside Purple mattress

Inside the Purple Mattress

The original Purple mattress combines high-density foam layers with its proprietary Purple Grid to provide maximum comfort, support, and pressure relief. A soft and stretchy cover encases the mattress to enhance its breathability and a dense layer of support foam secures the mattress’s structure. 

  1. SoftFlex Cover: Breathable and stretchy cover that emphasizes the flexing properties of the Purple Grid. Feels soft against the skin and keeps you cool by increasing airflow.
  2. Purple Grid: Designed to contour to areas of tension like your hips and shoulders to provide pressure point relief while supporting your body’s curves.
  3. Dual-Layered comfort foam: Adaptable comfort layer that rests on top of a support layer. Consists of soft dense foam that increases both durability and comfort.
  4. Support foam: Medium-firm foam that gives structure and support to the mattress as a whole.
Inside Casper Original

Inside the Casper Mattress

Three soft foam layers work in tandem to relieve pressure points and gently contour to your hips and shoulders. The foam still feels bouncy and responsive while also providing airflow.

  1. Airscape breathable foam: Memory foam top layer that increases breathability to dissipate body heat.
  2. Zoned support layer: Consists of three ergonomic zones that distribute weight evenly to provide support for areas of pressure like the hips, shoulders, waist, and lower back.
  3. Durable support foam: Works against body indentations and sagging to increase your Casper mattress’s durability.

Which Mattress is Best for You?

So which one should you choose as your new mattress? The Nectar is best for budget-friendly shoppers who like the feeling of sinking into their mattress. The Purple is best for those who suffer from back pain. The Casper is best for combination sleepers who love the soft feel of memory foam

The Nectar offers superior motion isolation and edge support, making it a great pick for couples. It’s one of the best bangs for your buck and offers some of the most generous warranty and trial policies in the mattress game. 

Purple offers pain relief and recovery which is ideal for active individuals. It’s the only mattress out of the three that excels in cooling, and the Purple Grid aids in pressure relief and support. The Purple is especially great for back and side sleepers.

With soft foam layers and zoned support, the Casper feels both plush and supportive. It’s universal firmness level fits every sleeping position, including stomach sleepers who would benefit from Casper’s zoned support layer. The Casper is your best bet out of the three if you’re a frequent belly sleeper who needs a bed that prevents sinkage while still keeping you comfortable.

If you like to feel hugged by your mattress for that cozy cradling sensation, then either the Nectar or Casper will work for you. Side sleepers would do well on any of these mattresses. Since the Purple is a hybrid mattress, it’s firmer and better for relieving back and neck pain while still keeping you cool. The main deciding factor between each of these bed-in-a-box mattresses is what sleep position you frequent the most and the kind of feel you like your mattress to have.

You can’t go wrong with any of these mattress companies, so the decision really comes down to what you specifically need out of a mattress.
