Toppers are a great way to make an older mattress sleep more comfortably. They are also a great addition with brand new mattresses. The Lucid 3 inch Gel Memory foam topper makes my granddaughters new big girl bed that much more comfortable and inviting. Her brand new mattress is so much more comfortable with this awesome super soft topper. Resting and sleeping on the 3 inch topper is so comfortable. It’s like sleeping on a cloud and waking up refreshed. It arrives neatly compressed and boxed with easy to follow directions. Love that this topper has the gel memory to keep the topper’s temperature comfortable. Mattress protector and fitted sheet easily fit over the topper and mattress. This Lucid brand topper is backed with a 3 year warranty too.
