Thin platform for shakers on top of carpet question.

Hi Folks,

I would like to build a small, thin platform basically made of plywood held off the floor by the kinetic islolaters as feet. My shakers will be attached to the platform rather than the furniture. The floor will already be carpeted with pad/carpet on a slap, so the kinetic isolater

So, how well do you think this will work? Shuuld I just skip this step and attach the shakers directly to the furniture? I currently do this now, but would like to get some more shake of the floor feeling.

Now that I think of it, I could put shakers in the ottoman, but the wires would be a problem.

Regards,

- Hal

Use of platform is better as it will send the sensation via your feet and furniture creating a very noticeable impact.

However you do not indicate the possibe dimesions of platform in your post. This will give me a better idea of how thin you can go. In anycase assuming that 2" - 3" is acceptable to you then you can use a series of 2x4's on their sides for the perimeter and center etc. of your say 4'x8' plywood platform and attach the feet on the plywood not the 2x4's to save space (you may have to add an additional piece of plywood between the feet and the platform plywood to get the feet to stick out beyound the 2x4's). Also do not forget to glue and screw when building the platform.

I am considering doing the same thing, primarily for ceiling height issues. I will have 4 Berkline 090s in the front row-(center love-seat flanked by wedge arms & a chair on each side~137" from the Berkline spec sheet) Do you think this would work?

I was also thinking about running some rope lights around the periphery.

It should work for you too - see the web site for other ideas:

I plan on making as thin a platform as possible. Perhaps 1 layer of plywood pieces and whatever framing I can get away with to hold them together. I do not want to make risers or any thing like that for multiple rows. I have a sectional sofa combo that is two love-seats that we put together have a slight curve to them. My ceiling is just over 7', so space is a premium.

So, I was thinking of using steel framing (on it's flat side) to hold together the plywood. I could even put the kinetic isolators in flange of the steel framing. The shakers (Aura's now, Buttkickers later) would be mounted to the platform under the couch.

My main question is that if I build this platform, it will be resting on an already carpeted floor. How well will the kinetic isolators perform as legs if it is put on a soft surface rather than a slab. The more I think about it, perhaps the flanges of the steel framing can act as an isolator. But, I have never worked with steel framing and perhaps it could bend if the flanges are used as support legs for a platform. Also, I would need 12' long sections of steel framing. I assume they make that.

What do you guys think? Let me know if this is confusing and I can make a diagram.

Regards,

Hal

You need to have some sort of frame to support it, using solid metal may significantly reduce the amount of thickness.

I don't think that there is a difference with the isolators being on a carpet, their job is to isolate vibration, or in this case to isolate the floor from the vibration.

You may explore the possibility to create a metal platform and attach the isolators to one side, and the furniture floor contacts to the other.

In my previous home, I created a 2x6 platform, big enough for the floor contact of 2 recliners to rest on it, my feet were a little on the air, but since they were recliners, it did not matter.

On my new house I have a 7' basement, and I am considering doing the same, but I will have a riser, so it needs to be a big platform. We'll see what I come up, but I am still a year away from it.

Good luck.

if you are going to use 2x4's, you'l want to use plenty of isolators to give the platform support - otherwise it will bend and flex too much from the weight of the seating and occupants. I had to do this with my 2x4 platform, but it works really well.

Placing the isolators on the carpet should not make a difference.

Sime,

How exactly did you build your platform - size, placement of 2x4, shape, how many and placement of isolators etc. And how many isolators did you use originally when you said it was too flexible?
