Comparing Construction (Materials & Quality)

Signature Hybrid Construction

This item is a foam and coil hybrid, that ships compressed in a box.

The cover of this 12-inch mattress has Super Soft Quilted Thermic Phase Change Fabric and gel-infused memory foam quilted into it to create a 1-inch topper that should prevent overheating.

New layers of the Sparrow mattress
  • The top layer contains a 3-inch Energex™ Temperature Responsive Foam. This cutting-edge material should provide an immediate response for when you change positions.
  • The second layer holds a SmartFlow Support Foam coming in at 1 inch thick. This 3-pound high-density foam serves as a transition layer to provide support as you move into the coil system.
  • The third layer contains the 6-inch Quantum Edge Pocketed Support Coils. The Quantum Edge should provide enhanced edge support while the coils add stability to the entire mattress.
  • The final layer is made from dense foam that helps support the coil unit.

Casper Construction

This is an all-foam product that is shipped compressed in a box.

This 11-inch mattress features a polyester cover that can be removed with a convenient zipper.

  • The top layer is comprised of breathable AirScape Foam. This is a proprietary material that is meant to promote airflow which could help prevent overheating.
  • The second layer contains Zoned Transition Foam. The zoned areas are meant to provide varying levels of Firm, Medium, and Soft feels for exceptional comfort, spinal alignment, and pressure relief.
  • The bottom layer consists of Durable Support Foam. This provides stability and durability for the entire bed.

Comparing Firmness (Support & Feel)

Both mattresses land very closely on the Firmness scale (learn more here) with the Sparrow Medium at a 5.5 and Casper has a 6. This scale assumes that 1 is feather soft while 10 should feel rock firm. Because of these versatile comfort levels, both options should appeal to most back, stomach, or side sleepers depending on comfort preference.

Sparrow offers multiple Firmness options so shoppers can choose a feel that best suits them, and Casper’s zoned design should offer personalized pressure relief that adapts to the sleeper’s weight and position.

Those who do prefer a slightly Softer experience, like side sleepers who require less pushback on the shoulders and hips, for example, may prefer the Hybrid mattress since it’s slightly more plush.

Shoppers with significant weight concerns can check out the Sparrow or the Casper Wave options as they should provide a little extra support. Sparrow also comes in a Plush version for those who prefer an even softer feel.

The Sparrow should have a somewhat slower response time than the Casper, though deeper layers should respond quicker than the upper layers. The Casper materials should reshape quickly when compressed. A faster response time should allow the materials to reshape quickly as you move around, allowing for easier repositioning.

Comparing Sinkage and Bounce

This is the area where these two products will likely differ the most. The Signature should provide a deep hug, more like the traditional memory feel, while the Casper should present with a gentle cradle. Those who like to sleep “in” the mattress might opt for Sparrow, while those who want to stay “on top” might prefer the other.

Both items should provide moderate bounce which should ease in repositioning. Anyone who considers this a major concern might want to opt for Casper as its upper layers tends to be a little springier and more responsive.

Comparing Motion Transfer

Both of these beds should provide excellent motion control. The Sparrow's hybrid construction may contain higher amounts of movement due to the coils, but the coils are individually pocketed, which should help to absorb the movement more than a traditional innerspring would.

Either product should perform well in this area, but those with motion control as a very significant priority, such as co-sleepers with restless partners, may want to opt for the vibration dampening, all-foam Casper product.

Comparing Edge Support

The Sparrow mattress should offer exceptional edge support when lying or sitting at the edge because of the sturdy Quantum Edge coil system. The Casper also performs better than the industry standard. Its sturdy layers should provide a consistent feel when lying at the edge, while a slightly deeper compression may be noticed while sitting, though this is not usually a dealbreaker for most shoppers.

Overall, either option should satisfy buyers in this area. Those who value this feature very significantly may opt for the Sparrow as it’s Quantum Edge coils may give a little extra support when either lying or sitting at the edge of the bed.

Should I Buy the Signature Hybrid or the Casper?

After rounding up all the pertinent information and key features, which of these two options is best for you?

Both items should provide similar levels of support, bounce, and motion control. Your preference may lie in sinkage level, construction, or cooling capabilities. Check out the recommendations below for an idea of who each mattress should suit best.

We Would Recommend Buying Sparrow if You are Looking for:

  • Enhanced cooling. Multiple layers of cooling materials with technology and gel promote a cool sleep experience. Breathable and aerated lower layers help to promote airflow.
  • A deep hug. If you like to sleep “in” your mattress you should enjoy the deep hug and body-contouring provided by this bed.
  • A premium hybrid experience. Comfort layers and individually pocketed coils combine to bring together the sinkage and pressure relief with the support of the coils.

We Would Recommend Buying Casper if You are Looking for:

  • A gentle cradle. You should find yourself sleeping more “on top” of this mattress with much less sinkage than with the Sparrow.
  • An adaptable all-foam construction. The foams inside this product are zoned to adapt to your weight and position. This should provide ample back support and pressure relief as-needed. Co-sleepers should enjoy a personalized feel as the materials compress or pushback to suit their individual needs.
  • Enhanced motion control. Those with restless partners or pets should enjoy the minimal motion transfer provided by this mattress thanks to the denser layers that should help to dampen energy.

Final Thoughts

Sleepers of most styles should find either brand suitable for their needs thanks to the Signature’s multiple comfort options and Casper’s universal comfort level. Where these products differ are in the nitty-gritty personal preference areas that are often vastly different from person to person.
