I read the reviews and the mattress is exactly what is advertised.Its very firm solid mattress.True to size with no unpleasant odors .If you prefer a firm mattress this is the one for you.i added a pillow topper and it is pure bliss I am extremely happy with the purchase JUST BUY IT one thing to be mindful of is when you open it please be careful and prepared for it to have a extremely serious inflating and unraveling

reply from GREOO

Hello Character! Thank you for your honest and detailed review. We’re glad to hear the mattress is exactly as advertised—firm, true to size, and free of unpleasant odors. It’s wonderful that pairing it with a pillow topper made for such a blissful sleep experience. We also appreciate you sharing the tip about being careful when unboxing, as the mattress does inflate quickly once opened. Thank you for your recommendation, and we’re thrilled you’re happy with your purchase.

Get this mattress if you want comfort and quality

This is by far one great mattress! I've had many mattresses and I've slept on hundreds and this is one of the top two I've had the pleasure of enjoying. It's high up in thickness and the perfect firmness! I'm so very pleased with this purchase very pleased and satisfied

Great product

Great mattress, such a reasonable price. You could literally replace your mattress every two years and not spend as much as you would on one mattress in 20 years. Great mattress, such a reasonable price. You could literally replace your mattress every two years and not spend as much as you would on one mattress in 20 years. Very comfortable we chose firm and it is very firm. We love it.
