My suggestions:
1. Place child on sofa perpendicular to the edge, facing you as you sit on the floor. Assist them to keep elbows under shoulders. Speak and sing to them to distract them and encourage the head to lift. If the buttocks is lifting up, place your hands on buttocks and push gently down. This assists the weight shift that must occur to have the head lift.
2. In addition to above, if you need to, add a chest roll. Best way is to take two receiving blankets and fold them in half. Roll them together and place the roll at the baby's nipple line. Boppy pillows tend to be too high and the infant usually hangs in them. The value of tummy time is the shoulder work that occurs when we must support ourselves on our elbows. It also engages the chest and anterior (front) neck muscles.
In truth any mat would work with the chest roll described above. The real secret is the distraction. We use a mirror with the grandkids as well as the sofa method.
If all else fails, place child on your chest and you lay down. Again, support elbows under shoulders to help with the head lift.
Hope that helps. No real special equipment needed
