How much weight can tile handle? Will it help with cold floor? I'm looking to put them on top of our ceramic tile floor and put TV stand and sofa on top of soft wood foam tile.

Our Premium Soft Wood Tiles are made of foam, so any amount of weight will cause them to depress to varying degrees. Since these tiles are made with closed cell EVA foam, they will provide you with excellent insulating properties. For any heavy furniture, we recommend using Furniture Sliders underneath the furniture legs to prevent permanently damaging the floor.
