Mattress Comparison: Saatva Classic vs Back Science Series 2
When it comes to finding the right mattress for back pain relief and overall spinal health, both the Saatva Classic and the Back Science Series 2 stand out as premium hybrid mattress options designed with support in mind. The Saatva Classic offers a more traditional innerspring luxury with customizable firmness levels, a plush Euro pillow top, and dual-coil support tailored for a wide range of sleepers. In contrast, the Back Science Series 2 is engineered specifically for back pain sufferers, using scientific testing to ensure proper spine alignment and a balanced feel across all sleep positions.
This mattress comparison dives into their construction, performance, and value to help you decide which one best aligns with your needs—whether you’re prioritizing versatile, hotel-like comfort or targeted back relief.
TL;DR Verdict
For those seeking customizable firmness and a bouncy, responsive feel with white-glove service, the Saatva Classic Mattress edges out as a solid luxury pick, though it may not match the targeted support for severe back pain. If back pain is your primary concern and you want top-tier spinal alignment, exceptional cooling, and durability, go for the Back Science Series 2 Mattress—it’s a game-changer for chronic issues.

Mattress Construction & Design
Saatva Classic Mattress
Luxury hybrid – 11.5″ or 14.5″ height, 3 firmness options:
-
Organic cotton cover + Guardin™ antimicrobial treatment
-
3″ Euro pillow top with Lumbar Zone quilting
-
High-density memory foam lumbar layer
-
Zoned active wire support (14.5-gauge recycled steel, firmer center)
-
Foam-encased edge rails
-
13-gauge base coil unit (heat-treated for durability)
-

Back Science Series 2 Mattress
12″ hybrid designed by chiropractor Dr. Rick Swartzburg:
-
Cooling bamboo cover
-
4″ ventilated hypergel comfort foams
-
Patent-pending Lumbar-Flex™ zoned lumbar support
-
Reinforced ResiliFlex™ edge system
-
1,000+ pocketed coils (Quantum Edge)
-
CertiPUR-US® foams • GREENGUARD Gold certified
Delivers a luxury-firm feel with targeted back support and excellent airflow.
Takeaway: Both are hybrids emphasizing lumbar zones, but the Back Science Series 2’s zoned Hypergel foams and edge barrier provide more innovative, targeted reinforcement, while the Saatva Classic leans on a classic pillow-top and dual-coil setup for a traditional bounce.
Firmness & Pressure Relief
Saatva Classic Mattress
Offers three options: Plush Soft (4/10), Luxury Firm (6.5/10), and Firm (7.5/10), but all feel firmer than stated (overall 7/10). Pressure relief (7/10) comes from the memory foam layer and Euro top, providing gentle cradling for side sleepers on Plush. Some users report long-term firmness loss leading to aches.
Back Science Series 2 Mattress
Rated firm at 7/10 (luxury firm feel, 6–8/10 range), it excels in pressure relief (9/10) with Hypergel-infused layers that contour to the body without sinking, promoting spinal alignment across all positions. The Lumbar-Flex system targets the lower back and hips, reducing pressure points effectively—ideal for back pain, with 97% of users reporting improvement.
Takeaway: The Back Science Series 2 delivers more consistent, science-backed relief for back pain, while the Saatva Classic’s customization suits varied preferences but may not hold up as well over time.
Cooling & Temperature
Saatva Classic Mattress
Rated 7/10 for temperature neutrality, thanks to the dual-coil airflow, breathable organic cotton cover, and antimicrobial treatment. It’s suitable for most but may not suffice for heavy overheaters, falling short of the hype.
Back Science Series 2 Mattress
Top-rated at 10/10, with the Kool-Flow bamboo cover, Hypergel foams that disperse heat, and a patented Airflow Transfer System offering up to 100 times more breathability through micro-vents and channeling. Sleepers report noticeably cooler, pleasant nights without feeling cold.
Translation: Back Science Series 2 wins for hot sleepers with its advanced venting; Saatva Classic is reliably neutral but less innovative.
Edge Support & Motion Isolation
Saatva Classic Mattress
Edge support (7/10) starts strong with foam rails but sags after 6 months per some reviews. Motion isolation (7/10, 7.5/10 in tests) is average for a bouncy hybrid—responsive for changing positions but transfers some movement.
Back Science Series 2 Mattress
Edge support is 9.5/10, with a minimal 5.4-degree drop thanks to the ResiliFlex barrier and Quantum Edge coils—great for sitting or sprawling. Motion isolation (9.5/10) is excellent via individually wrapped coils, outperforming many hybrids for couples.
Couples Math: Back Science Series 2 minimizes disturbances better; Saatva Classic is decent but noticeable.
Off-Gassing & Eco
Saatva Classic Mattress
Rated 6.5/10: Breathable organic cotton cover and recycled steel coils, but GREENGUARD certification claims are misleading (not listed on site); slight odor lasts under a month, with natural thistle barrier.
Back Science Series 2 Mattress
Rated 9.5/10: Greenguard Gold and CertiPUR-US certified, low V.O.C. emissions with a mild new-foam smell that dissipates quickly. Non-toxic and eco-focused materials.
Takeaway: Back Science Series 2 edges out for verified eco-credentials; Saatva Classic has some green elements but inconsistent claims.
