See the Nectar Premier on our product page for the latest deal—it crushes the Novaform in cooling and trial length.
Built for value, the ComfortGrande layers gel memory foam (about 2-3 inches) for contouring comfort over transition foam, then a 7-inch high-density polyfoam base for durability. The stretchy polyester cover includes phase-change material to wick away some heat, measuring roughly 14 inches tall total. At 80-90 lbs for queen, it's hefty but compresses for Costco delivery.
Overall score: 72/100. Solid for budget foam, but lags in cooling and edges.

Best for budget side sleepers (120-230 lbs) sharing with a partner, or guest room use. Skip if you're a hot stomach sleeper, heavyweight, or want strong edges/365-night trials.

Check TEMPUR King (scale to Queen needs)
Protect your investment with the Queen Size Mattress Protector—waterproof, bedbug-proof, and hypoallergenic for under $30.
Yes for budget buyers—strong motion isolation and comfort at $700 queen, but average cooling holds it back from top tier.
Medium (5-6/10), suiting 70% of sleepers per our surveys, especially sides.
Relies on Costco's return policy (anytime within membership); no dedicated 100+ night trial like Nectar.

It's average (3/5); opt for Nectar or Saatva Graphite for better temp regulation.
