This is our new Serta, other mattress we had was also Serta, had 20 years, this is a great mattress, not too soft , firm but comfortable, we love it, went to local furniture store where this same mattress was *** more than we paid on Great Offer Stock, but we were able to lay on it and decided it was the one and then ordered from Great Offer Stock, free delivery and White glove set up, guys were awesome that delivered, timely and professional, and they had to carry up to second floor of an old Victorian home, they were great, thank you for another awesome product!
