Comparing Construction (Materials & Quality)

Alexander Signature Hybrid Construction

This item is a foam and coil hybrid, bed-in-a-box product.

The polyester and cotton blend cover boasts a 1.5-inch Gel-Infused Memory Foam along with Thermic Phase Change fabric quilted into it. This should help to keep you from feeling overheating as you sink into the comfort layers. The total height of this mattress is 14 inches.

construction and layers of alexander hybrid
    • The top layer is a 1.5-inch TitanChil Endurance Foam layer. This is meant to promote cooling and pressure relief.
  • The second layer contains a 1.5-inch Copper Infused Energex Foam. This material should further promote a cool sleep by conducting heat throughout the entire mattress and away from the sleeper.
  • The third layer consists of a 1-inch SmartFlow Support Foam. This material should promote a neutral spine and even weight distribution while the aerated nature of the foam should promote airflow.
  • The bottom layer is comprised of an 8-inch Quantum Edge Pocketed Support Coil system. This should maximize the usable sleep surface and help to minimize motion transfer. Both of these features should be ideal for co-sleepers.

Saatva Construction

This mattress is a hybrid product that combines memory foam and two coil units. It is shipped compressed in a box.

The cotton cover encasing the 3-inch Euro Pillow Top has been treated with GuardinⓇ, an antimicrobial treatment designed to inhibit bacteria growth. This company offers two mattress heights, 14.5 inches and 11.5 inches. We will focus on the construction of the 14.5-inch mattress as that is closest to the height of the Signature, differences between the two heights will be noted below.

saatva layers image
  • The top layer contains a thin layer of .5-inch Lumbar Support Enhancement. This is a memory foam and wire system that promotes neutral spinal alignment.
  • The second layer is comprised of Individually Wrapped Coils standing 4 inches in height. These foam-wrapped coils should help to minimize motion transfer and provide personalized comfort and support as the coils are meant to react to your individual body weight and position.
  • The bottom layer is made up of 7-inch Steel Coil Base Support. This system is devised of recycled, tempered steel and is meant to provide overall stability for the entire bed. This system is an estimated 4 inches in the Slim Profile 11.5-inch version of this product.
  • The perimeter boasts Dual Perimeter Edge Support. This is a reinforced foam support surrounding the upper comfort coils to provide extra support along the edge.

Comparing Firmness (Support & Feel)

We are using a comfort (firmness) scale that uses a 1-10 system to determine the feel of these two beds. This system sees 1 as the Softest you can get and 10 as the absolute Firmest. Both items provide multiple comfort options.

The Signature’s Medium ranks at a 5-6 out of 10. The company’s Plush option comes in at a 2.5-3 and the company’s Luxury Firm has earned an 8.5-9.

Firmness scale for Alexander Signature Hybrid mattress

The Saatva’s Luxury Firm sits at a 6 out of 10 on this scale. The Plush Soft should feel like a 4 and the Firm version has earned a 7.5-8.

Firmness scale for Saatva bed

As you can see, a wide range of comfort feels are available from each brand. Alexander tends to span a little more of the scale, swinging from very Soft to very Firm. Saatva tends to stay a little closer to the Medium range with all options.

The Alexander should provide exceptional pressure relief as the thick foam comfort layers and coil system, which is designed to compress or stand firm depending on your weight and position. Saatva’s mattress should excel with enhanced support, having two different coil systems to cradle your shape and support your spine.

Stomach sleepers may prefer the Firmer end of the spectrum, while side sleepers typically opt for Softer feels. Shoppers of all preferences should be able to find a specific comfort option that best suits them thanks to the wide variety available across these two brands.

The Signature should present slower response time in the upper levels, with a quicker deep response. The Saatva should respond quickly with a slower response time noted in the lumbar region.

Comparing Sinkage and Bounce

Those who want a deep, comforting hug should appreciate the deep sinkage of the Alexander. Buyers who would rather float on top of their mattress will likely prefer the gentle cradle of the Saatva.

Both products should contain plenty of bounce, though you may experience more on the Saatva due to the dual-coil systems. Either way, both products should do well in providing easy repositioning for combination sleepers.

Comparing Motion Transfer

Many buyers do not consider motion transfer to be a dealbreaker when choosing a new and perfect mattress for them, which should mean either product is a viable option for most shoppers. If this does happen to be a considerable concern for you, you may want to consider the Signature, as its multiple layers of foam should dampen slightly more energy than the connected steel coils inside the Saatva which could allow movement to travel throughout the bed.

Comparing Edge Support

Alexander features a row of Quantum Edge Coils to stabilize the edges. The Saatva contains reinforced foam. Both of these items should offer exceptional edge support, which is often a plus to those who share their mattress with partners, children, or pets as co-sleeping can lead to disruptions as partners move around in the night.

Should I Buy the Alexander Signature Hybrid or Saatva?

These two brands offer incredibly different products that are likely to suit specific shoppers’ needs. Different sinkage levels, construction, and feels are likely to mean there is one clear-cut winner for your own personal needs. Check out our wrap-up below that takes a closer look at which item is likely to work for you.

We Would Recommend Buying the Alexander Signature Hybrid if You are Looking for:

  • Foam with enhanced cooling. Multiple gels, phase changing technology, and individually pocketed coils should ensure you will never overheat even as you sink deep into this mattress.
  • A deep hug. Shoppers should notice deep sinkage and a contouring that hugs the body. This should provide comforting pressure relief.
  • Customizable comfort. With multiple Split King options available, buyers may choose to order two different comfort feels to suit couples who require different comfort levels.

We Would Recommend Buying Saatva if You are Looking for:

  • Enhanced lumbar support. Back sleepers should enjoy the extra level of lumbar support offered by the foam and coil system inside this mattress.
  • A gentle cradle. Buyers who prefer to sleep “on” and not “in” their bed should love the gentle cradle the Euro Top is meant to provide.
  • A classic innerspring feel with a lot of bounce. This product provides a classic innerspring feel with two coil systems. Shoppers should enjoy ample bounce that should ease movement.

Final Thoughts


These two products offer different coil experiences are likely to appeal to different types of sleepers. Comfort levels, construction, sinkage, and cooling are quite different across the two. This should help you to narrow down your shopping choice to the bed that fits your own personal priorities.

Whichever mattress you decide on, you can rest easy knowing both brands offer quality products with a lot of value. Check out our in-depth reviews for a closer look at each brand.

When I’m not learning about sleep, you can find me hanging out with my wife and close friends.

I absolutely love entrepreneurship and learning how to improve yourself daily. We only get one life, and I want to make it the best one possible.

I hope that everyone that finds our site takes a new approach to sleep. The world needs to stop thinking about it as something “we just do,” but rather something that allows us “to do every day.”

We will be happy to hear your thoughts
