Higher-weight sleepers who weigh more than 250 pounds might find a pillow-top mattress does not provide the necessary support needed for comfort and spinal alignment. The plush nature of pillow tops can lead to excessive sinking, which could strain back muscles and joints over time. For higher-weight sleepers, a firmer mattress with a thinner, more supportive pillow top layer might be a better option to ensure both comfort and adequate support. Alternatively, they may want to choose a mattress specifically designed for higher weights.
