Extra Firm Mattress Topper Twin 3-inch Memory Foam + Support Foam, Double-Sided for Sleeping, Pain Relief, High-Density Firm Mattress Topper with Removable Cover, CertiPUR-US Certified, 75" x 38"

I purchased this topper because I wanted to make my bed firmer. After I unpackaged it I let it sit on the bed for 48 hours before I put the cover back on and made the bed. It is definitely firm enough. I like the option that I can flip it to the blue side for it to be a little softer but so far so good for the money.

I bought this mattress topper for my son and it has been amazing! After opening the box, it does need 24–48 hours to fully expand, but it is well worth the wait. Before this topper, my son constantly complained about poor sleep and back pain. Since adding it to his mattress, he sleeps so much better and no longer has any back pain. He even doesn’t want to get out of bed in the morning because of how comfortable it is! I’ve tried it myself and love it too t’s not too soft and not too firm, just perfectly comfortable. Highly recommend!

When I was injured my daughter came to help me and ordered me a new bed, an XL Twin med. with side rails. Way too soft and felt like the middle had a big hole in it so I couldn't move or turn without the guard rails. I bought this topper and the one side is EXTRA FIRM which I am sleeping on, which made all the difference. I love this topper so I can sleep now and get out of bed without back pain. Soooo nice! The topper also has med firm on the other side. What a Godsend to me as I was ready to give this entire bed away and buy a correct one. Thank you.

My grandson had a difficult time sleeping on mattress that was recently purchased. it was a medium firm. H e needed to get a pillow top that was firm. We saw this one and purchased it. He doesn't have the back problem anymore.

As I’ve gotten older, I’ve needed a more firm mattress. After reading the reviews, I was nervous to purchase. However, this mattress topper exceeded my expectations. I have finally gotten a good nights sleep.

I wanted an extra firm topper so far this is doing the job. I'll give it a month to see if it maintains it's firmness. As it is, I highly recommend if someone needs an extra firm topper.

First off, I cannot afford a new bed/matress so this is better than having to get a new bed. Anyway, my matress is old and it had a topper on it already--got t from my grandson; it was his. Previous height: 9 in matress 3 in topper = 12 inches. My two sets of sheets that I purchased without realizing sheets are different depths--were for a 15 inch drop. So since the sheets were practically new i just added another 3 inches--why buy new sheets? They were practically new--I just needed 3 more inches to make them fit. This new topper on top of the old topper has worked just fine and now my 15 inch depth sheets fit fine. Plus the bottom sheet and the matress pad that i had on my bed already, once put on the bed, held it all together just fine. In the picture it appears the topper is too big but it isn't anymore. I purchased this b/c I wore out my favorite sheets that fit snuggly. The BIG ONE sheets with the 15 in. drop were always wrinkled in the middle of the bed. Ugh. When my old well-fitting sheets wore out, I thought of getting new sheets but why get new sheets when it was just that the other sheets were just too big? Why not get another matress topper to put on the other topper. Two toppers? To equal 15 inches. Yes, Beause this topper has straps to hold it in; and also the sheets and matress pad holds it in--its perfect. Nothing slides off the bed. It seemed a bit too big at first as you will see in the photos, but it now fits the bed well; i think because it takes a little while for it to completly expand. I put it on my bed the day it arrived. I turned the brown side up that is more firm side, and I like the firmness since i had a bit of a valley in the old topper before putting this one on top. I didn't know sheets came in different sizes--i just thought a queen size sheet was a queen size sheet, the end. But anyway, this mattress topper solved my problem and I've had it now for a few weeks, so far so good. It took me a while to type out this review so I hope it helps someone with their decision. You just have to remember its not going to be like a whole new bed and you have to be realistic with your expectations. I'm happy with it. Hope the photos help your decision. Good Luck.

Oh this is perfect! Firm and fantastic. I think the others it’s all depending on what you are looking for. But firm and comfy!

This topper is very firm. Initially I did not sleep well as I was adjusting to it. The first night felt like I was sleeping on a plank of wood. But over time it adjusts to your body and you sink in just enough to support your whole body. It definitely makes you want to sleep on your back more as that’s the most supportive position. If you need a firm mattress, but you already have a medium level firmness and don’t want to buy a new mattress, this topper is for you!

With the mixed reviews i hesitated ordering this topper. But I decided to try it for the price. Topper was slightly oversized for my twin XL. It is definitely firm but comfortable. I had spinal fusion surgery and if I slept four or more hours on my mattress, I would have pain and ache. I’ve not had any pain or aching since we put the topper on. For the price I would definitely recommend.
