Buying Guide
- Size and fit: Measure the pool’s outer edge to ensure the cover is compatible with an 18-foot round pool. Some fabrics require extra edge space for a secure seal.
- Wind resistance: Look for triple or reinforced windproof designs, weighted edges, and ratchets or screw-in anchors for storms and high winds.
- Material and durability: 420D–500D Oxford fabrics with UV coatings provide long-term performance; higher scrim counts (like 14×14) increase tear resistance and snow load tolerance.
- UV and weather protection: Choose covers with UV protection to prevent sun damage during partial-season use and to extend life through winter sun exposure.
- Ease of installation: Perimeter grommets, built-in winches, and clear tension systems lower install effort and improve fit stability.
- Maintenance and cleaning: Surfaces with closed seams or heat-sealed seams reduce debris infiltration; reflective strips aid night visibility for safety during storage or removal.
- Compatibility notes: Some models specify compatibility with steel-wall vs. frame pools; confirm your pool type and model year before purchasing.
- Warranty and support: Check warranty length and what it covers (material defects, wear, wind damage) to understand long-term value.
