Winter Air Pillow 1148 – In-Pool Cover Air Cushion
The Winter Air Pillow 1148 is a heavy-duty, inflatable vinyl air cushion designed to protect pool covers during winter months. By supporting the pool cover and distributing weight evenly toward the center, it helps prevent rainwater and debris from accumulating, reducing stress on the cover, anchors, and pool edges.
Key Features
- Heavy-duty vinyl construction — built to resist cold-weather stress, UV exposure, and extended outdoor use.
- Inflatable air-cushion design — supports pool cover and helps water and debris flow toward the center for easy removal.
- Replaceable valve — enables easy inflation and allows for season-after-season reuse.
- Universal fit — works with most rectangular and standard-shape winter pool covers; number of pillows needed depends on pool size and cover dimensions.
- Compact storage — deflates for easy storage once winter season is over.

When & Why to Use
Use the 1148 air pillow when installing a winter pool cover — especially on in-ground pools. It helps prevent excessive water pooling and debris accumulation on the cover, reduces stress on anchors and coping, and protects the cover from stretching or tearing under weight. It’s a simple, effective tool for extending the life of your pool cover and making end-of-season maintenance easier.
Maintenance & Storage Tips
- After placing under the winter cover, inflate to about 75% capacity — fully inflated pillows can press tightly against pool walls.
- Monitor air pressure periodically during winter; adjust as temperature drops or as seasonal temperature swings change internal pressure.
- Before pool reopening, deflate the pillow, rinse with fresh water, dry completely, and store in a cool, dry place away from direct sunlight to preserve vinyl integrity.
