Most Motion Transfer

I’m looking for an innerspring coil from Leggett and Platt that has the most motion transfer for a bedbound family member–the opposite of minimizing motion transfer

Hi Sooz,
Welcome to the Mattress UnderGround Community.
While I dont have much information on where to purchase for a DIY, assuming that is the nature of you question, the following will offer some information on which coils you should be considering.

Generally, innerspring coil system with the most motion transfer, is one that is connected with a continuous coil. It appears that you’re looking for a mattress that responds to movement in a way that might help with position shifts, though it will be more reactive overall.

Leggett & Platt is known for their high-quality innerspring coils, and the key to achieving motion transfer (rather than minimizing it) is to look for a coil system that is more responsive and allows more movement. Here’s what you should consider:

  1. Bonnell Coils – These are typically the most basic and traditional type of innerspring coil. They tend to transfer motion more than pocket coils or other more advanced systems because the coils are interconnected, so when one coil moves, it can affect others across the surface of the bed.
  2. Offset Coils – These coils are a bit more complex than Bonnell coils and can offer more motion transfer than pocket coils but not as much as Bonnell coils. They are designed to offer a balance of support and responsiveness, so there will still be some motion transfer but not to the extreme extent of a basic Bonnell coil.
  3. Continuous Coils – These coils are made from one long wire, which creates a more uniform support structure. They may transfer a bit more motion than individual pocket coils, as they share motion across the connected structure.

If it is not obvious, you will want to avoid pocketed coils from Leggett & Platt or any coil manufacturer for that matter, as these are designed to minimize motion transfer by allowing each coil to move independently. If you’re looking for a higher level of motion transfer, something in the traditional innerspring category would be ideal.

Not all traditional open and continuous coil designs are ideal for motion control. However, innovations and cross-design approaches have enabled some systems to improve motion responsiveness by altering the way the coils are constructed, even with a thick border wire surrounding the spring support layer.

Hopefully, this helps,
