  • Works great!
Size: 17x13x1.5 with 17"x13"x1"
After 2 nights using these supports, I will say it's the best $21 I've ever spent. Our mattress is higher-end but several years old--and suddenly getting out of it is actually painful. My only back problem occurs when waking up, and took me longer than it should've to notice that little sag. Hoping to avoid replacing the mattress again, I ordered these and started with the thinnest pad. I can't explain what it was like to just hop out of bed with zero discomfort. This simple and inexpensive fix made such a HUGE difference. Highly recommend! ... show more

  • Perfect Support! Place them where your mattress and body need the most support.

Very Comfy. They were perfect support for my mattress.

  • Firms Up / Provides Support for Too Soft or Sagging Beds - Great for Hotel Travel
Size: 17x13x1.5 with 17"x13"x1"
These do exactly what I needed them to - I have a bad back and I travel a lot for work. Sagging hotel beds that aren't as firm as I need them to be to begin with are not helped by not being flipped and rotated on a regular basis. I would get up in the mornings and barely be able to walk - it only got worse the more nights in the offending hotel bed. I purchased these and have not had a problem since. I usually only use two of them under the mattress where my lower back is and they provide enough support to firm up any bed I've encountered enough for a good night's sleep and pain free mornings. I got a couple of bungee luggage straps and roll them up to make them take up less space in my suitcase. The foam has discolored a bit with age and temperature exposure in the cargo hold, but the integrity of the foam and support it provides has not been compromised. I've used these more than a year now and I highly recommend for a low cost, low hassle remedy to saggy or soft mattresses. ... show more

  • ONLY 2 PADS
Size: 17x13x1.5 with 17"x13"x1"
While I am happy that a pad worked well, I don't understand why there are only 2 in the pkg. You can see 3 in the photo and it says 3 in the description. Am I supposed to cut one in two? There are 2 identical pads in the pkg. So just beware. If you need 3, you're getting 2.

  • Bed slumping no more!

Great support and a lot cheaper than buying a new mattress.

  • In love
Size: 17x13x1.5 with 17"x13"x1"
Right now I'm feeling like this is the best $20 I could've spent. My partner was telling me we should buy a new mattress but it's only 6 years old so that was a no go for me. Figured I would chuck some money at it to see if we couldn't get a few more years out of it. I was dubious that these would work. They don't look like much. I just stuck these cushions under the problem area at the edge of the mattress and WOAH! I didn't realize how much tension was in my back until I started feeling it melt away. Looking forward to a fantastic nap here soon! ... show more
