For couples with different firmness preferences, a 3-inch topper provides a compromise that suits a wider range of needs. It offers more pressure relief than the 2-inch version for those who need it, while still maintaining a firm surface for those who prefer more support. Most 3-inch toppers come in a Twin XL size, which is perfect for one-half of a split king mattress.

Finally a good night’s rest!
After reading all reviews about the high density mattress topper I decided to purchase one in 3 inches. I ordered it on a Wednesday night and surprisingly received it Friday afternoon which was awesome service ! I removed it from it’s packaging and immediately install very easRead more about review stating Finally a good night’s rest!ily and it was ready to out right of the box. I have an extra firm sterns and foster mattresses which I purchased 5 yrs ago. Since then I was diagnosed with a slipped disc and have severe neck and back pain from time to time, however in the past three months the pain has bern consistent. After sleeping on this mattress one night I immediately felt relief. I didn’t toss and turn like I usually do I was finally comfortable due to the softness of the topper. The topper doesn’t slide around it stays balance and in place thanks to the adjustable straps. This topper is a game changer for me it added the right amount of softness to my extra firm mattress, and now I don’t have to replace my mattress woohoo ! I’m so happy with my purchase from Viscosoft and I’m so thankful that I’m able to get a good nights rest again. Now my mom and sisters want one too since we all have extra firm mattress but now dealing with injuries and need better support. This toppers definitely will give you relief and a better night rest weather your dealing with injuries or just need to soften a firm mattress. Thank Viscosoft I’m so glad I found you. I definitely will continue to spread the word to others.

My 2nd topper
I loved my first topper (3 inch) so after a couple of years I decided to go with the 4 inch. Love it as much as my first one. Would recommend it to anyone.

Goldilocks topper
One of us has scoliosis and the other has osteoarthritis. We both love our 3-inch Select High Density topper. This is our third topper. We have had two other Read more about review stating Goldilocks topper3-inch toppers from other brands but those never came close to being this good. We like this one so much we bought a second one to use in our other location. It's not too thick and not too thin; it's not too hard and not too soft; it's not too cool and not too hot; it's easy to keep our bedding without lots of wrinkles and bumps; and it's easy for us to move around in bed. For us, the 3-inch Select High Density is our Goldilocks of toppers! THANK YOU !!
Transformed a too firm mattress
Placed the 3” topper over a firm new mattress and transformed it into a soft and cozy bed. Our guests at the cabin tell us the bed is extremely comfortable. Great purchase!
3” queen short topper
I’d give it a six star if I could! We are using the topper to go over our camper mattress and we finally had a comfortable nights sleep camping. We weren’t sore in the morning either . The website descriptions helped us get the right size for the small space we have and was shipped fast.
Great Topper
We have a latex mattress which we need for firmness but still needed a little more softness for pressure points, especially shoulders. This topper made such a difference. The straps keep it firmly in place so that it doesn’t slide. We got the 3 inch which works perfectly. So cRead more about review stating Great Topperomfortable and doesn’t get hot.

The Reflex mattress topper is suited for all sleep styles. Three-inches of gel-infused memory foam offers enhanced motion isolation...absorbing and reducing movement, ensuring minimal disturbances from a partner's shifting or getting out of bed. The resilient foam has an excellent rebound effect for more uninterrupted sleep and fewer body aches in the morning. Each Reflex topper is precisely cut to fit every mattress size. This allows an everyday fitted sheet to secure the topper to the mattress.
Integrity to the Edge
Details Matter
Three inches of high-quality foam form a stable, supportive layer that reduces sinking and eliminates the "dumped" feeling when sitting on the edge of the bed. This added stability ensures consistent, even support across the entire mattress, allowing you to feel comfortable no matter where you lie. If you're looking for a topper that offers both enhanced comfort and durable edge support, 3-inch options offer an ideal balance for long-lasting stability and restful sleep.
