Review: Absolutely Perfect!! - This mattress topper is perfect for my mattress. I got a twin bed frame and mattress set from my sister. The mattress is old and when sleeping on it, I found myself sinking into the mattress and was waking up with my arm numb and back pain. I bought this exact mattress topper in 2023 for my daughter’s college dorm bed. She used it 2 years, then gave it to our neighbor to use at her dorm. When my other daughter went to college last year, she used it for her dorm. During the summer, we brought all her stuff home from college. I tried the mattress topper and it was glorious! No more arm numbness or back pain. You “sink a little due to the thickness and give of the memory foam, but it supports the body and maintains its shape when you get up. It is plush to provide comfort but firm enough to not be too squishy. It comes in a very tiny box due to shrink wrapping. Follow the written directions and use the “envelope opener” enclosed so you don’t cut into the foam. Let it sit opened up a full 24 hours. It started expanding within minutes in a couple of spots but by the next day was fully expanded. I let it sit for 48 hours. There was absolutely no odor. I put a waterproof mattress protector on top since you can only spot clean foam. I have included a picture of the old one bought in 2023 to show how well it held up. The old one will be returning to my daughter’s dorm. It is slightly yellowed on the edges and a little discolored due to the age and use, but still feels the same and works perfectly. I do think the holes help with cooling, but covering it with a regular mattress protector makes it less effective. I am going to purchase a cooling mattress protector to try. It is much cooler than the other memory foam mattress I tried. The foam was a perfect fit. On a side note, I bought a “Serta Cooling” topper at a nearby store and tried it for a few days. It was horrible. It was so hot to sleep on and the foam did not “recover” and it did not help with my back or arm. I highly recommend this product. You won’t be disappointed! Note: The last photo is the 2023 topper.
Review: Great mattress topper - Bought this mattress topper for my son’s dorm room bed. Definitely know dorm room beds can be pretty uncomfortable in general. He says it is SO nice and super Comfortable! It unfolded easily out of shrink wrap packaging when we got to his dorm room, it did not have any wrinkles or creases In it at all. We just let it lay flat on his bed and get some air for a bit while we did other things to get him set up that day and it was great. My son said he sleeps so good and his bed is super comfortable!

## Questions & Answers

**Q: What does the cooling gel infusion do, and will it keep my mattress cooler?**
A: Cooling gel is blended into the foam to help draw heat away from your body and regulate sleep temperature. The open-cell foam structure and ventilation channels also promote airflow for a cooler sleep experience than traditional memory foam.

**Q: Is there an odor when it arrives, and how long until I can sleep on it?**
A: A mild new-foam scent is normal and fades quickly. Unroll in a ventilated room for 24–48 hours. By the time it fully expands, the smell should be gone.

**Q: Will my current sheets still fit?**
A: Measure your mattress plus your topper height before ordering sheets to ensure a snug fit. The added height may require deep-pocket sheets (15"+ depth).

**Q: Which thickness is right for me — 2", 3", or 4"?**
A: The 2" adds subtle softness to a slightly firm mattress. The 3" delivers deeper pressure relief for back and side sleepers. The 4" is ultra-plush, ideal for very firm or worn mattresses.

**Q: Can I wash this topper?**
A: The foam can't be machine washed. Spot clean with mild detergent and a damp cloth. We recommend pairing it with a waterproof mattress protector to keep it fresh long-term.

### ⭐⭐⭐⭐ Soft Dreams or Sinkholes? A Lucid Mattress Topper Tale
*by C***R on September 17, 2024*

Oh, the Lucid Topper, so soft and so blue, It arrived in a box, and it knew what to do! I unpacked it quick, with a zip and a glide, And in less than an hour, it puffed up with pride! My bed was too firm, a bit hard like a rock, So I got this soft topper, thought I’d give it a knock. And soft it sure was, like a marshmallow dream, You sink right in, like you're lost in a cream. But beware, dear shopper, it's squishy, you see, If your bed's plush already, it might not be key. For sinking too much, oh, you might get stuck, So firm beds only, to really press your luck! It slides just a bit, so don't toss too wild, Or you’ll wake up slanted, like a giggly child. The cover I got? It was loose at the seams, With strings hanging out, not as neat as it seems. But all in all, I’ll give it a cheer, Though not perfect, it’s cozy, and brings comfort near. A 4 out of 5, not bad, I’d say, A good choice if firmness keeps sleep at bay!
