What if the bed is too soft?

1, add a thin layer of brown pad on the mattress. The palm pad is hard, so you can buy a palm pad the same size as a bed in the market and superimpose it on the original mattress, so it won't be too soft. 2. Use a joinery mat. You can make a joinery board of the same size under the mattress and put it under it. 3. Put a soft mahogany between the bed sheet and the mattress. Mahogany can effectively prevent insects and increase hardness. 4. Use bamboo mats. If it is summer, you can spread a bamboo mat, so that you won't feel the mattress soft.
