I must say I was amazed at the total comfort for the price. When I first received my mattress I hadn’t purchased the frame.  I felt that I needed to add the right frame for the mattress, so I purchased the 18” SmartBase frame, so glad I did.  The bed sits high off the floor which leaves plenty of storage underneath. The bed feels more supportive with this frame.  I love the mattress, I thought it felt to soft but then you get into bed and it’s perfect, cradling you in pure bliss.
