I was a little skeptical at first with the idea of a mattress in a box but oh my am I glad I decided to buy this! This is the best mattress I have had in years and would never go back to a regular one! I also bought two Polysleep pillows and I juste love them! Have no doubt this mattress does not disappoint. Ordered this on a friday and Monday is was already at my door! Thank you Polysleep.
