4' Swing Bed Cushion - 4 Inch Thick Black Outdoor Furniture Cushion - Waterproof & Weather Resistant - Perfect for Porch, Patio, and Backyard Relaxation

This is a perfect fit and very high quality, comfortable cushion. It has a very nice feel... Firm but hugs you. Like a high quality foam mattress in my opinion. My wife said she thought it was a bit expensive. But I haven't heard her complain once she laid on it. It is the perfect compliment to the swing! I bought the gray one (which looks greige on Amazon but it's actually a nice light gray in person). I highly recommend it!
