12Pack Adjustable Deck Support Pedestal Deck Foundation Base Support for Floating Deck Platform Deck Floor Height Adjustment Raising from 2-3/8"" to 5-1/2"", Black

Interesting item. I am in process of doing some deck repair and thought I would give them a try. I think I ordered a dozen and have used all but three of them. The ground underneath my deck is not at all level so adjustable seemed like a logical option. They worked out very well and in places that were lower, I simply put a block or paver beneath the adjustable one. They are very easy to install and not too expensive. Only time will tell how well they hold up, but they seem sturdy enough.

I recently built a very large shed and wanted to use a floating pier system as the ground was uneven and had compound slopes. I purchased a series of these in multiple sizes and they worked perfectly. Adjustments were super easy and the bases were very wide for great load distribution. I placed these on 1'x1'x2" pavers, which gave them room to move and settle as I proceeded with frame and subfloor joist construction. As I built the main frame to which these the piers were attached to, the increased weight compacted the ground underneath, and it was very easy to tweak the height adjustments on these piers. I would absolutely buy these again!

I’m using these item for the shed I’m building, they worked out great.

I used these to build (replace) a 16x22 floating deck. I also supplemented the install with a few of my original posts that were still solid in concrete. I used pavers with these to get the deck level. They seem well made and unless you are parking a hot tub or a car on the deck, I don't see them failing. I have built over 15 decks in my life and I wanted to avoid using concrete and 4x4 posts this time. I was replacing a large deck that had rotted out after 19 years. The ground was already flat and level, so these were a great option. The adjustment is the key. If anything, buy extra to distribute the weight properly. Too few of them would definitely be a problem.I would absolutely use these for any size deck that is low to the ground. Level ground is key however.

I utilized these as the base to build my hot tub deck. Super easy to use and super strong. Makes installing a deck on un-even terrain pure simplicity.Very easy to adjust, just build your frame, then just turn the knobs until the base of the deck is level, then just put on the top boards and you’re done.These just work and makes deck building easy. I built a 10x10 in under an hour and a half. Highly recommend.

These worked amazing! I bought the smaller 12 pack to level a floating deck for my greenhouse, effortless! The price compared to others is crazy cheap! My deck is 8x8 and I used all 12.

Put these under a small shed I needed leveled. They immediately crumpled, poor quality plastic, no strength at all.

Work as expected, wonder how long they will last, not suer they how long they will last.
