The top layer of the mattress feels a bit too much like those old egg-crate shaped foam. That is, it offers little to no support and feels "cheap". Combined with the lower layer, the feeling is that of being too firm, at least to my liking. I feel pressure/ache towards the middle of my back as a result of this firmness, something I did not feel with my older memory foam mattress (which was not as firm). I've been sleeping on the mattress for about 10 nights now.
The simplicity of the process of ordering and setting up the mattress was reason enough for me to recommend a tuft & needle mattress. The comfort of the mattress and the quality of sleep I've experienced since using the mattress is why I'm giving it a 10/10 recommendation.
