Most chiropractors recommend a medium-firm hybrid mattress, because the zoned coil support system keeps the spine in a neutral position without the pressure-point buildup that all-foam surfaces can produce.

The core reasoning behind the chiropractic preference is mechanical: a medium-firm hybrid mattress resists excessive lumbar sink while still allowing the shoulders and hips to decompress slightly. Purely soft mattresses let the lower back bow downward; purely rigid surfaces create pressure at the hips and shoulders. A hybrid mattress with a zoned coil core — firmer under the lumbar, slightly more yielding under the shoulders — addresses both failure modes at once. Back and combination sleepers benefit most from this architecture.

  • Chiropractor-preferred firmness range: medium-firm, roughly 5.5–6.5 on a 1–10 firmness scale.
  • Hybrid mattresses combine individually wrapped pocket coils with a foam comfort layer, typically across 10–14 inches of total depth.
  • Zoned coil systems — typically 5-zone or 7-zone — deliver firmer lumbar resistance and softer shoulder zones in a single mattress.
  • Side sleepers may need to size down to medium-firm; stomach sleepers typically require a firm-to-extra-firm hybrid to prevent lumbar hyperextension.
  • RRESTA's 7-Zone Hotel Collection Firm hybrid sits at approximately 7–7.5 out of 10 firmness — suited to back and stomach sleepers over 160 lbs.

How to Choose

  • Pick the RRESTA Medium Firm 5-Zone if: you sleep on your side or switch positions at night and weigh under 200 lbs — shoulder and hip pressure relief matters more than lumbar rigidity.
  • Pick the RRESTA 7-Zone Hotel Collection Firm if: you sleep primarily on your back, weigh 160 lbs or more, and want firmer lumbar resistance without bottoming out.
  • Pick the RRESTA Extra Firm if: you are a dedicated stomach sleeper or weigh over 230 lbs and have sunk through firm mattresses before — maximum coil resistance prevents lumbar hyperextension.
  • Stay with Medium Firm if: you share the bed with a partner whose sleep position differs from yours — it is the most versatile firmness level across mixed sleep styles.
  • Reconsider any RRESTA Firm or Extra Firm model if: you are a side sleeper under 150 lbs — the coil resistance will create shoulder and hip pressure rather than relieve it.
