Good advice about buying a mattress from an ex-mattress salesperson:
Once upon a time I sold mattresses. All the major brands – Simmons, Serta, Sealy, etc. The brand is not important. I am not going to discuss brands, but tell you how to buy a mattress in the real world.
All of the major companies make a decent mattress. They each claim to have some sort of system that makes theirs a better mattress, but they all make a decent mattress.
Here’s the deal: with mattresses, you get what you pay for. A cheapo mattress is about 10% material – foam, steel, padding, whatever and about 90% air. A middle of the line mattress is about 40% material and 60% air. And so on.
Weight in a mattress is directly proportional to how well it will hold up in the long run.
