Mattress Helper Mini Under Mattress Support Extender- Fix Your Sagging Mattress No Sag Firmer Solution for Mattresses - Mini Extender

it may not look it. i was skeptical about this. i have a nice big dip in my mattress on my side of the bed. i tried stuffing blankets, pillows , random stuff several times under my mattress everywhere. still kept waking up with the samr back problem. i decided to buy this (its been several months now). and so far no back problems! the bed feels comfy again and i think this product did the trick! only needed to use one to fix the dip. i woild highly recommend this.

There is a noticeable improvement on the sag and this help me sleep much better, all thou I do recommend to get 2 instead of just 1 so you can line one on the top center and the other one more on the bottom center of the bed in between the box spring and the mattress. I think it would have a much better accomplishment, otherwise the bed looks and feels like it has waves or hills. Overall is good, but if they added more pieces to one, it would be better.

This product made my back hurt even more than it did prior to the purchase. I even bought the extender because i thought i needed more.

Too thin to do anything

This product really works! It saved me from buying a new mattress after the store I got it from wouldn't honor the warranty. My back pain is gone!

Size of item, smaller than I expected, however it worked wonderfully Despite the fact that I could’ve used a larger size. It did provide extra support for a weak spot in our mattress. I would recommend ordering a size larger than what you actually need.

Have not used yet, but appear to be as described but a little smaller than I expected. Also quite heavy and bulky for storage (since I am using them on a sofa sleeper).

NOT WIDE ENOUGH FOR CAL KING .NO "BUY OPTION" FOR WIDER UNIT ??UPDATE: Emailed company had reply in less then 24hrs buy the owner resolved problem .I can now actually sleep on my expensive but stupid laytex mattress

This is a great product to eliminate mattress sagging and total rejuvenates your otherwise good mattress. I used two of these under the mattress and now feel like I am sleeping on a brand new bed. I purchased them for all of the beds and now do not have to worry about buying new mattresses before time. I highly recommend this product.
