YEARS ago I ordered this 4" memory foam topper in King. I had a Queen sized bed back then, but thought I could get creative with the extra width. I trimmed it to fit the queenbed and ended up with plenty left over to make pillow-liners. I slept on it for many years and absolutely loved it. Eventually, I purchased the 14" memory foam mattress from Overstock in King, and I have been equally pleased with that. My topper finally ended up cut into sections that I took the the SPCA to use as dog cage pads. Even the dogs looked comfy on it. The only thing I found that isn't perfect with this topper is that the foam will discolor over time, it turns a funky yellow color from the air but who sees that? I wouldn't hesitate to purchase this topper, I never knew what a comfortable bed was until I discovered memory foam.
