Sleep soundly on this 12" Copper Gel Cooling Memory Foam Mattress—designed for comfort, coolness, and everyday convenience. The copper-gel infused foam keeps you cool all night (no more sweaty wake-ups!) and fights odors, so your bed always smells fresh. Edge-to-edge support means a stable surface—no rolling off when you sit to tie shoes or read, plus 20% more space for couples. The Air Grid Base is breathable and flexible, working seamlessly with adjustable bases so you can lounge, read, or watch TV in perfect comfort. It ships compressed and rolled—quick delivery, easy to move, and sets up in minutes. And the machine-washable zip-off cover? A lifesaver for spills, pets, or busy families. Soft, supportive, and built to last, this mattress gives you the rest you deserve without breaking the bank.
