The answer is: "Not likely". There are some exceptions.
The most important factor is the weight of the sleeper.
The mattress is designed for the majority of people. About 90 % of sleepers will have
no problem with either of our models. Obviously, extremely heavy sleepers may deflect
the mattress beyond its ability to fully cushion the bar.
The issue is the density of the mattress foam. The denser
the foam, the more forgiving the mattress. If you think it might be a problem,
we urge you to consider our platinum
grade.
No other sofa bed mattress can beat our quality in an any respect. As regards
feeling the bar, our products excel.
