In cold\/wet conditions (snow, ice), ice crystals can form in the valve — wipe the valve clean before opening\/closing. If the valve sticks or doesn't hold air, check for debris and rinse with clean water.

To preserve the welds between cells: avoid over-inflation (the cushion should feel firm but not rock-hard), don't sit on sharp objects, and inspect periodically for signs of cell separation. If individual cells fail, the cushion will develop soft spots but can still be used (just less comfortable).\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"key-section\"\u003e\n\u003cdiv class=\"key-title\"\u003e75D Polyester Care\u003c\/div\u003e\n\u003cdiv class=\"key-desc\"\u003eThe 75D polyester face fabric is durable enough for regular sitting use but not indestructible. Avoid contact with sharp objects (broken bleachers, sharp rocks, exposed screws on chairs) that can puncture or tear the fabric. For small punctures: clean the area, apply a TPU\/polyester repair patch (STS repair kit or generic), and allow to cure for 12–24 hours before use.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"key-section\"\u003e\n\u003cdiv class=\"key-title\"\u003eTHERMOLITE HL-1 Insulation Care\u003c\/div\u003e\n\u003cdiv class=\"key-desc\"\u003eTHERMOLITE HL-1 is a synthetic insulation that requires similar care to other synthetic insulations:\n- \u003cstrong\u003eKeep dry\u003c\/strong\u003e — wet insulation loses loft and warmth.
