I was expecting a 4-inch thick memory foam mattress topper in a white or cream color. I received a yellow and blue streaked egg-crate shaped product clumps of blue gel injected throughout low-grade foam. After allowing the pad to expand for 24 hours, it not only strongly smelled of chemicals but felt sticky to the touch due to the poorly integrated gel. Furthermore, the "4-inch" aspect is deceptive. Yes, at the peak of the egg-crate points the product is 4 inches tall, but at the low point of the product, the pad is less than 1 cm thick. I returned the product after finding it completely ineffective, texturally unappealing, and deceptively advertised.
