Need Help Deciding?
For most sleepers, we recommend the Amerisleep AS6 Black Series Firm over the Purple RestorePlus Hybrid Mattress. It scores higher in edge support, price-to-value while costing $950 less for Queen ($2,649 vs $3,599). The Purple RestorePlus Hybrid Mattress is the better choice only if you specifically prefer a softer, more plush feel.
Amerisleep AS6 Black Series Firm vs Purple RestorePlus Hybrid Mattress: What Actually Differs
Both the Amerisleep AS6 Black Series Firm and Purple RestorePlus Hybrid Mattress are hybrid mattresses, so the real differences come down to firmness tuning, performance ratings, and price rather than construction type. The Amerisleep AS6 Black Series Firm stands 14" tall versus 13" for the Purple RestorePlus Hybrid Mattress — a 1.0" gap that matters if you need deep-pocket sheets or are pairing with an adjustable base. The Amerisleep AS6 Black Series Firm is the firmer of the two at 8/10 (firm), and the Purple RestorePlus Hybrid Mattress sits at 4.5/10 (medium-soft) — a meaningful enough gap that sleeper position and weight should drive the choice. The single largest performance gap is in edge support: the Amerisleep AS6 Black Series Firm rates noticeably higher than the Purple RestorePlus Hybrid Mattress, which is the deciding factor if that dimension is high on your list. On a Queen, the Amerisleep AS6 Black Series Firm runs $2,649 versus $3,599 for the Purple RestorePlus Hybrid Mattress — roughly $950 (26%) less, which is enough to factor into the decision unless the pricier model wins clearly on the specs you care about.

Amerisleep AS6 Black Series Firm
Strengths
- ✓Firm keeps the same AS6 construction and current price as Luxury Firm and Plush Soft while providing the least sink and Amerisleep's firmest 8/10 surface
- ✓Three inches of Bio-Pur memory foam sit above Affinity transition foam and a 6-inch pocketed PrecisionCoil core, giving the firm surface contour and spring response rather than a flat all-foam base
- ✓The CryoCool cover, TitanAir foam, and ArcticWave bands address heat at three parts of the comfort stack; these are manufacturer claims rather than SleepRanked lab results
- ✓The coil core and 1-inch BaseGuard are the strongest AS6 direction for shoppers who prioritize easier repositioning and a more usable perimeter
Considerations
- —The 8/10 surface is a poor starting point for strict side sleepers and anyone who needs deep shoulder and hip cushioning; Luxury Firm and Plush Soft keep the same construction and price with more give
- —Amerisleep publishes cooling, pressure, alignment, motion, edge, and durability claims, but SleepRanked has not independently measured those outcomes
- —Amerisleep does not publish separate thicknesses for the TitanAir, ArcticWave, or Affinity portions of the current stack
Purple RestorePlus Hybrid Mattress
Strengths
- ✓Deeper grid than Restore
- ✓Strong pressure relief for hips and shoulders
- ✓Hybrid airflow and support
- ✓Zoned coils provide targeted support
Considerations
- —Not offered in standard Twin
- —Premium price tier
- —Softer feel may not fit shoppers wanting firm support
