System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1650/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.09

Blender Version
Broken: version: 2.91.2, branch: master, commit date: 2021-01-19 16:15, hash: blender/blender@5be9ef4177
Worked: (newest version of Blender that worked as expected)

Short description of error
[When i click on the bottom (3) cushions for sitting on and go in to sculpt mode it goes all spiked and say's "Number of points in cache does not match mesh" ]

Exact steps for others to reproduce the error
[Click on 1 of the sitting cushions and go into sculpt mode]
[Based on the default startup or an attached .blend file (Blend file)]

Thanks

Two issues here:

- Your cloth cache is outdated, you need to rebake it:
  (this probably happened because something changed in the stack prior to the cloth modifier -- possibly the subd levels on the subdivision modifer above?)
  
  If you do this, you'll get rid of the Number of points in cache does not match mesh" error as well as the spikes going to sculptmode.
- Sculpting with active physics modifiers is not going to give you expected results. You will alter the underlying original mesh, but this will not get feed into the simulation result, so this is not going to work out.
  There might be (better) ways to communicate this [in form of documenting this or giving a popup warning in the UI], but this would not be considered a bug.

Workflow wise, you are advised to keep a copy of the sim object, but for further sculpting, apply the modifiers, see https://youtu.be/4h097E4pRCw?list=PLjEaoINr3zgGgS-N9Ews90bDAYYLoP0NO&t=986
