The term “a sinking feeling” is generally a precursor to something ominous, but in the world of memory foam, it’s very desirable — and is the only way to describe the feeling of lying down on this Tempur-Pedic mattress topper. “Wow,” I said out loud, to no one, as I disappeared into the cloud-like expanse. I wasn’t going to spend the whole night on the floor, but the fleeting moment of relaxation made me really excited to spend a full night with the topper on my bed. My current mattress, an innerspring queen with a pillow-top, is only about four years old — aka not quite old enough to replace but definitely starting to get a little long in the tooth (and, more technically termed, lopsided in its support distribution) — so the topper seemed like the perfect solution. (Note: three inches doesn’t seem like a lot, but modern mattresses are already quite tall, so the topper gave my bed a pleasingly hefty height of Princess and the Pea-like proportions.) This wasn’t connected to my physical comfort in any way, but it definitely made my bed look more appealing. Climbing into bed on the first night, I uttered the same refrain from earlier in the day: “Wow.” I laid on my side, sunk into the mattress, and promptly drifted off to dreamland.
