Casaluna Temperature Regulating Sheet Set Overview
Casaluna's Temperature Regulating Sheets put genuine 37.5 active-particle technology into lyocell for around $90 — the cheapest credible cooling sheet set, with a thinner hand feel than premium rivals.
Our Review
These Casaluna sheets use 37.5® active-particle technology embedded in lyocell fibers to dynamically regulate your body temperature. The fibers capture and release heat to maintain the ideal microclimate next to your skin. At Target's price point, these offer cooling performance that rivals sheets costing three times as much.
Our Hands-On Experience
37.5 technology embeds active particles in the fiber that respond to body humidity, moving moisture vapor away before it becomes sweat. It is a real, measurable mechanism rather than a coating, and at $90 it is by far the cheapest way to get it in a sheet set.
Lyocell is the right carrier fiber for it — sustainably produced, smooth, and naturally moisture-managing on its own. Together they made a set that our warm-sleeping testers rated close to sheets costing twice as much.
The hand feel is where the price shows: at 300 thread count they read thinner than premium sets, the sateen finish is slippery for some sleepers, and colors are limited. Buy them for cooling performance per dollar and easy Target returns, not for luxury feel.
What We Love
- 37.5® technology actively manages temperature
- Very affordable for cooling sheets
- Available at Target — easy to buy and return
- Lyocell is sustainable and eco-friendly
- Decent durability for the price
Room for Improvement
- Not as luxurious feeling as high-end options
- Limited color selection
- Sateen weave may be too slippery for some
- 300TC feels thinner than premium sheets

Great cooling for the price
These won't feel like $300 sheets but the temperature regulation is real. I wake up dry for the first time in years.
How We Tested the Casaluna Temperature Regulating Sheet Set
Every bedding set we review goes through our rigorous, multi-step evaluation process. Here's exactly how we arrived at our scores for the Casaluna (Target) Casaluna Temperature Regulating Sheet Set.
Sleep Panel Testing
Each bedding set is tested by 4+ panelists with different temperature preferences and skin sensitivities over 10+ nights, including multiple wash cycles.
Breathability Testing
We measure air permeability using standardized airflow tests and track skin-surface temperature overnight to quantify cooling or heat-retention properties.
Fabric Hand-Feel Analysis
We evaluate softness, drape, and texture using both tactile panel ratings and a fabric stiffness tester to objectively score hand-feel across materials.
Wash Durability
Each set undergoes 20+ wash/dry cycles following care instructions. We measure pilling, shrinkage, color fastness, and hand-feel degradation post-washing.
Value & Certification Review
We verify certifications (OEKO-TEX, GOTS, Fair Trade), compare price-per-quality across the category, and factor in warranty and return policies.
