This foam is not firm and gave no shape to my mattress. I ended up just shoving a piece of plywood under my bed with a 2x4 under it just above the middle and the ends strapped down. Worked like a charm for $20.

I often sit on the end of my bed. Over time this has caused a sag right at the edge I sit at. I went out on a limb and purchased this product. It just happened to work out perfectly. It has solidified the edge of the bed when I sit there and provided support. 100% would recommend.

These are wonderful. We have a 13” king sized memory foam mattress that has two “butt groves” in it. I unpacked and left to expand only for a few hours. We placed them on each side, and had to position them correctly, as they weren’t big enough to cover the whole width of the mattress. This worked out fine for us though. We are getting better sleep and my back isn’t in horrible pain every morning! Definitely worth the money. I would definitely buy again for foam mattress. Not sure how effective they would be on a spring mattress.

Enven my new 10 month old $1,000.00 soft mattress started to sag, so I looked online for how to help with sag, I see this on Amazon and gave it a try. I was very surprised how a special shaped foam would help with sagging mattress, it works great.....

I bought this to add support to memory foam mattress. The sides of the mattress are firm but the middle was sinking. Im a side sleeper so I would get bank pain from sagging middle pulling at my back. This support pad works great! I actually slept all night first night of use and didnt wake up with a stiff back. I definitely recommend for memory foam mattress support.

I am so excited. I returned one instantly from Yarfyk. What a piece of garbage. This on the other hand is perfect. It is a dense, firm foam, has good taper and works. I am putting it under my 3" memory foam on top of my inexpensive 5 year old rv mattress. It is working and I am so excited as I was not able to stand up strainght getting out of bed. I will sleep on this for the first time tonight. It also did not need to expand. And it does not have a crease in the middle, and is only a few more dollars than the awful piece of garbage that the Yarfyk foam is. I am so grateful. Please give it a try. I honestly don't know how it would work underneath my not very thick mattress, but I am trying this first and it is GREAT. I am a 74 yr old woman very petite, weight less than 80lb. I hope you will be as successful as I am right now in finding an inexpensive solution. As I will be moving from the RV in a year or two, I did not want to invest in another inexpensive mattress. Give it a try.

I used the TANYOO Sagging Mattress Support Pad under my THSUPER Sectional Sleeper Sofa with Pull-Out Bed, which was only two weeks old, and it noticeably improved support. Even though the sofa was new, the pull-out bed section felt slightly uneven, and this insert helped create a firmer, more stable surface. It also made the seating area more comfortable by preventing early sagging.Downsides? While it enhances firmness, it doesn’t drastically change the overall feel of the sofa. Also, the foam may compress over time with frequent use. But if you want a quick, affordable way to reinforce a sleeper sofa, it’s a solid choice.

Good quality for the price, had a lot of expectations so ended up ordering 2 but was disappointed excuse it is too think, tried three nights but could hardly sleep. Almost not usable due to the thickness.
