The quality is excellent, and I would recommend the firm one. One thing I will add is that it hugs the mattress really well and doesn't move around like the previous one we owned.
This is our second topper we have bought in the lase few months and it's clearly made with higher grade materials. The price we paid for the last one was more than our new Puffy one.
So far it has given us that extra support we need. My husband likes firmer mattresses and this did the job when we added it to the king size Puffy.
WOW! We are obsessed with this Puffy Topper. Absolutely love this topper, it's more supportive than we expected.
Worth it, it feels perfect. Thank you for the quick shipping also!
