Mattress Helper MINI Under Mattress Support Extender- Fix Your Sagging Mattress Firmer Solution for Mattresses - MINI Extender

I've never liked to write reviews, but now I feel like I should tell everyone how I use it because I buy things on Amazon by referring to all the reviews to decide which item I need, so if you're just a single bed, I don't suggest you to buy it because it doesn't work at all if you have a full or queen bed then you can buy the small piece fixer because it does work on my full size bed so can't say this product is not good at all

Wished it was better but it’ll do

I use these to lift up the mattress on my moms bed . They are a lifesaver .

California King Instructions: Buy the 1 x King set which includes two pads. Then buy 2 x "Mini 31" pad which completes the length of the mattress. You will need TWO Mini 31s to do this. We caught a better price at Target online for the King set and then bought the Mini 31s through Amazon. We could not find the Mini 31s offered anywhere else. Total cost for everything was (King $100 + 2 x Mini 31 $60) = $160.The set itself seems to be working well. We are using this in conjunction with a Stearns & Foster pillowtop that is sagging. It seems to be helping for the most part; it is a "helper" but not entirely perfect for fixing the sag on each side. However, this beats buying a new mattress for the problem. It seems like a waste to keep buying more mattresses because of sag.

Inhad my doubts. My matress started to develop a sink hole in it after only 2 months of having it. I went online to see what I could since I could not afford a new matress. I got this and it actually works wonders. My matress is firm now and the sink hole is gone.

It is helpful to raise the foot of the bed ... I have a bigger one for the middle where the mattress sags ... only complaint - why not make the main one long enough to fit the bed, so you don't have to buy YET another thing??? It is a bit over-priced, but better than having to buy a new mattress....

Perfect! I use it under my adjustable bed mattress.

Great product! I have a slightly beginning to sag mattress on a platform frame. Unfortunately the sag falls in a spot on the frame that is open. I tried plywood but it was too hard. This product was not only a great price, it works! It is firm but not hard. Contoured so you cannot feel it. I am cery pleased and am going to buy another for our guest room.
