Firms up a soft mattress!

ALDecember 18, 2025

Works great even if the mattress is made of memory foam gel! I would definitely recommend for back pain from a soft bed. Read more

Added Support for a New Sectional Sleeper Sofa

Yendor1760February 18, 2025

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. Read more

Skeptical

Dunno what conditions others put it thru... but it's ideal for mine

tinkererOctober 18, 2025

There were quite a few voices here who felt this mattress support was substandard (designed to fill into the sag mattresses develop when wearing out). Quite a few lauding it too... so decided to give it a try. Let me tell you -- this foam support is ~$10 less than just a cooling mattress cover (twin) by Allerease at my local Target. So was eager to see if this was actually good, or just more plausible deniability from fly-by-night companies. My first night on this thing... could not believe what a difference it made. I'd been nursing an $800 mid-grade conventional mattress 10 yrs now (similar models from the same brand's now $1100, thanks covid price-gouging), so defo on its last legs. Filling in the sag with towels and other support worked for years... until it didn't. This Tanyoo were basically the last resort before having to finance another damned expensive mattress (dislike the vast majority of foam ones, as far too many state even reputable brands last a third or less years vs. this brand of conventional. So despite massive savings... foam mattresses aren't an option for me). There was quite a bit of finagling around I'd have to do some nights, to get that pile of folded towels just right as to not create back problems... so got quite good at it. One replacement w/ this Tanyoo and throwing all that stuff out, actually fixed it. Not sure what those who claim this doesn't work ask of it -- am sure there are tonnes of grossly-overweight people, those who stomach-sleep (eeech -- neck problems much?) or those who sleep with a couple of poorly-disciplined 80-lb pets, all wildly mincing at their keyboards dissing this product. It's quite obviously not designed for those use cases. I'm just an 180-lb old dude screaming at clouds 😆 on a worn-out mattress with this Tanyoo beneath... and along with a nice mattress topper and cooling fitted sheets... am back to solid back-sleeping comfort thru the first night in *years*. Had been exp'g some pain and atrophy in R leg / knee due to a sciatic pressure point created with the deterioration. Now? That ache and warming routine all year on the wake-up? Gone in one night. Can't beat that. I mean, ~$35 for this insert delivered... if you're not one of the above way-too-numerous fringe cases, why the hell wouldn't you? Even if it lasts just a year, that's avoiding more than a grand in spending -- will take a few years then for this to convince getting another conventional mattress (and hauling it alone up into my walk-up) makes actual sense. Five stars for now. If any issues crop up in the next few weeks, will update here ⭐️⭐️⭐️⭐️⭐️ Read more

I recommend the purchase of these High Density Foam Pads

Carolyn EricksonJuly 30, 2025

I read reviews before I purchased and the one review talked about how their sagging bed was causing shoulder pain. I have been suffering the same even to the point of waking up with my arm(s) asleep. I ordered the two pack of the 47x25x1 inch pads for my queen size bed. I positioned them on top of mattress and under a 1 inch memory foam pad I had. I live by myself and that was way easier for me. I slept on them last night and felt much better this morning. The foam is dense enough that I don't think they will break down. A quick affordable fix! Definitely worth it! Hopefully a new bed in about a year or so! Read more

No

BuyerJanuary 11, 2026

Item looks a lot different from photo. Mostly a plain piece of foam. It comes rolled up in plastic. Not as thick and supportive as I thought it would be given the cost. Could've bought a cheaper mattress topper with better quality and cut it to make this. Read more

Love the added bonus support

Ms. OES1October 30, 2025

This made such a huge difference in my bed mattress!My mattress wasn’t sagging but I needed it for the added bonus support for my back. I slept on it and it actually helped with my back pain issues. Although, it placed height on my bed mattress ,I really enjoyed sleeping on it! Read more
