Post-form countertops are probably the quickest and easiest to install for the DIYer. These countertops consist of a laminate surface that is glued to a particleboard base. Because post-form countertops are somewhat fragile until they are installed, you should be careful how you handle and support the counters during installation. Take your time. Errors are not easy to correct or hide. Taking a little extra time with measuring and cutting is quicker than going back to the home center for a new counter.
