Under Mattress Support - Fix Your Sagging Mattress with Mattress Helper Firmer Solution for Mattresses -Single Side Coverage (Half Full/Queen)

I recently moved, and decided to buy a new mattress set, as my old one (which was about 8 years old) had pretty significant sagging. Both my old and new mattresses were king pillowtops, and I sleep alone - well, with my 50lb dog. I also have a fairly decent quality bed frame with more than the recommended number of cross beams/slats/supports/whatever they are called. I mentioned the sagging to the mattress salesperson, and his suggestion was of course to buy the most expensive mattress, which I of course did not do. After a few months with my new, second-cheapest-in-the-store-mattress, the sagging looked practically as bad as the old one!! Of course at that point the store's warranty had expired, and I was going to have to deal with the mattress manufacturer, so I just shrugged my shoulders and said f--- it...until I had back surgery a short while later, and found myself in need of a mattress that was not a giant piece of crap.So I turned to Amazon, which has lately been solving all of my problems at the expense of the poor UPS guy (sorry UPS guy). I found this, thought "oh bull honky, this is not going to do anything" but figured I could just send it back if it didn't work (sorry UPS guy). Once this was placed under my mattress, I could immediately see the difference - the sagging was pretty much gone! When lying down on it, it does not feel stiff or uncomfortable, nor does it feel like there was something underneath. I bought a firm memory foam/gel topper at the same time I purchased this (sorry UPS guy), in case this didn't work, and I ended up putting them both on at the same time. It's been several months now, and the combination is great. Still no sagging, I'm sleeping well, and it's very comfortable.As I sleep alone, even though I have a king size bed, I chose to go with the twin size. I read some conflicting opinions on this, but one twin was cheaper, and I figured I could add a second twin later if needed. It's working out great so far, no complaints from the dog!

I purchased my 1st 1 of these about 4 or 5 years ago and it's held up just fine. I put 1 Half Full/Queen under the side of my full size matress that I sleep on. I sleep alone so 1 was enough. The problem is as my mattress has gotten older it has now developed a sag in the center of the matress and it was causing me issues with my hip. So I knew I needed 1 under the center. My only complaint about these are that it's hard to figure out what combination of sizes will work be for your specific issue. I purchased another Half Full/Queen and 1 Twin/Half King. Unfortunately the length is now shorter on the Half Full/Queen compared to when I purchased mine so that ment I needed to purchase a 2nd 1. I did try 2 Half Full/Queen on each side of the bed. That's what is reccomend for a full size matress but that still didn't completely fix the sag in the center. So I tried out 1 of the Twin/Half king in the center wear the sag is but laying slightly off center more towards the side I sleep on.. This seems to be the better choice. 1 thing I want to say is when you place what ever combination you find right for you please make sure you put them at the head of the bed and not 1/2 way down the mattress. If you don't you might end up feeling vertigo/dizzy when you lay down. Despite having a regular pillow it will make you feel like your slanting down if you don't place it up by the head of the bed. If you use a wedge pillow at the head of the bed .... you may have to play around with the position a little more.*** For those who complain about the Matress Helper moving around .... try putting velcro (multiple pieces) on the top of the box frame where you want the Matress Helper positioned. Then place the other side of the velcro on the bottom of the Matress Helper .... making sure all the velcro lines up.

I have a 3 yo expensive all latex foam king mattress that started to sag, and I hated to spend thousands for a new bed...plus it seemed such a shame to throw this huge thing into a landfill. Since I was by myself, I thought I would try one mattress helper JUST on the sagging side- which was a mistake. It simply made a raised lump in the bed which was just as bad and uncomfortable as the sag. So I bought another MH to even things out, which worked...sort of. Because the MH was not as long as my bed I had dips at my head and feet- maybe this doesn't happen with an innerspring mattress, but my foam mattress needed to be raised the entire length in order to be completely flat and for me to be comfortable.I contacted the company and spoke with the owner / inventor of MH, and she told me they were coming out with a new MH mini and offered to send me several to try. The mini's look just like the regular MH but have fewer slats. I was sent mini's with 2 extra slats but for a king bed I really needed the 3 slat minis for a perfect fit. But the mini's I received did even out the head and foot of the mattress enough where I could be comfortable . I assume my issues with the MH not being long enough had a lot to do with the fact I had a HEAVY foam mattress and any part of it which wasn't supported by the MH would slope downward, just due to the sheer weight and flexibility of foam. The mini's fixed that issue by putting the MH under almost the entire length of my bed.I also had to put heavy cardboard under the MH because I have a foundation- not a box spring- which is essentially just a box with slats that the mattress rests on. Without the cardboard, parts of the MH would slip between the foundation slats, but once I put some support there that was not an issue. Wasn't a big deal, but you need to make sure the MH has a solid surface to sit on otherwise you won't get it to support the mattress like it should.I have now had the system in place for several months and the MH and minis haven't shifted or flattened out at all. There are so many different types of mattresses and mattress problems it is impossible to say if this solution will work for everyone, but I believe it is worth a try for most people. The owner of this company gives wonderful customer service and stands behind her product, giving you 30 days to see if it works for you. She really went out of her way to work with me to fix the issues I was having, and even followed up several times to make sure the MH and mini's were working. I feel strongly about supporting companies who care about their customers and give outstanding customer service ( often so hard to find !).... I am happy I found Mattress Helper!PS You may also want to try the mini's under a sagging sofa ....worked great for me.....I don't think the Mini's are on Amazon at this time but you can purchase direct from the company....and no, I don't work for them ( lol)....I'm just a customer like you!Update 5/29/16 ....About 6 months ago I had to bite the bullet and buy a new mattress. The helper is poly foam and eventually breaks down just like the poly foam in mattresses. So the mattress helper bought me some time, about a year. I had my parents buy the helper also and the same breakdown happened to them...helps at first but not long lasting. I also see a pretty big price increase for the product since I purchased it. Due to it's short lifespan and increased cost I'm downgrading to 4 stars. Still may be worth a shot for a short term fix, and I still think this small company owner givers great service...but don't expect a long term solution to a sagging mattress. PS.... If you are looking for a new mattress check out the many online mattress companies...Most are so much cheaper, higher quality, and stand behind their products MUCH better than retail stores.
