I bought an expensive ortho mattress which was so hard i was regretting buying it and then boom!I was rangoli mattress topper ad.I ordered one on sale and what a great perchase.I wake up little fresh every morning.i hope this topper does not lose its softness soon.only con is that i have to replace my fitted bed sheets becoz now the mattress depth has increased and bedsheet shows the quilting marks of this topper but i use a bed spread over my sheets.highly remomned for comfortable night sleep.I dont have an ac in my room as my room is in basement,i dont find this topper as sweaty.thanks seller a lot for making a quality product in reasonable price.
