This inner spring mattress is perfect! It’s very well made and comfortable all by itself. They got it right…no inner springs needed. It arrived quickly too and boxed well. I ordered a second one. You can’t beat the price for the quality you get. My husband said it was more comfortable than our $3,000 king mattress from a different company.😊 ... show more

  • Excellent quality 12inch full size mattress
I recently ordered this 12 inch full size mattress, and so far, I've been very impressed with how comfortable it is! I sleep on my side and back, and this bed supports both. I did allow this mattress to sit for a few days before first using. It measures 12 inches high and fits perfectly on my bed frame. I really like how well made this bed is. The quality of the construction is noticeable, and the materials are definitely higher end. It's soft to the touch and offers good back support. It's also very beautiful in appearance! Overall, this is an excellent value for the quality and phenomenal comfort it provides. I'd highly recommend this 12 inch full size hybrid mattress to others!! Thank you!! ... show more
