Pool Covers for Inground & Above Ground Swimming Pools

Protect your pool, retain heat, and keep debris out with the right pool cover for your inground or above-ground pool. PST Pool Supplies stocks a comprehensive range of pool covers from GLI Pool Products and Flexible Solutions — including mesh and solid safety covers, winter covers, overlap covers, and liquid solar covers for pools of all shapes and sizes, starting from $66.

GLI safety covers provide both protection and peace of mind. The GLI Secur-A-Pool Mesh Safety Cover (20' × 40', available in blue and green) is ASTM F1346-certified — it anchors to the deck around the pool with stainless steel hardware and supports the weight of a child or adult, preventing accidental drowning during off-season periods when the pool is uncovered. Mesh safety covers allow rainwater to drain through while blocking debris, keeping the pool cleaner through winter. The GLI Estate Solid Cover (24' × 40') is a solid vinyl winter cover that prevents all sunlight and debris from entering the pool — keeping algae growth suppressed during closure. The GLI Armor Shield (available in oval and round above-ground sizes) is a heavy-duty above-ground winter cover designed for the rigors of cold-climate closing. The GLI Classic Solid Overlap Cover for round above-ground pools is the standard round winter cover secured with a water tube or cable and winch system. For pools actively in use, the Heatsavr liquid solar cover collection from Flexible Solutions provides invisible heat retention without a physical blanket — see the full liquid cover lineup in our liquid solar cover collection.

Choosing between a mesh and solid pool cover is primarily a maintenance preference. Mesh safety covers drain rainwater through the cover, preventing water accumulation on the cover surface (which can create a drowning hazard and damage the cover) — but they allow some fine debris and algae spores to enter the water. Solid winter covers keep the pool completely sealed from debris and light (reducing spring algae cleanup) but require a cover pump to remove accumulated rainwater from the top surface. For all safety cover installations, anchor spacing and deck condition are critical — ASTM-certified safety covers require proper anchor placement per manufacturer specifications to achieve the rated load-bearing capacity. Professional installation is recommended for all inground safety cover installations to ensure anchors are correctly positioned and torqued.

Shop pool covers and protect your pool investment through every season — from summer heat retention to winter closure.
