Hi gundeep11,
Neither mattress description includes enough information to make any meaningful comments about either mattress. If you can provide the information listed here and post it on the forum then I’d be happy to make some comments about the quality of the materials inside each mattress. Unfortunately the odds are very low that you will be able to find this information out and the salespeople will likely have very little knowledge of the materials in any of their mattresses. In other words they have little to no idea of the quality of the mattresses they are selling.
Without this information I wouldn’t consider any mattress.
The odds are very high that there are lower quality foams in the comfort layers of both mattresses which would be a weak link in both mattresses. These lower quality materials have a much higher chance of softening, compressing, and sagging much too quickly which will generally can lead to the loss of comfort and support and the need to replace the mattress. Since the loss of comfort and support isn’t considered to be a defect in the mattress … it’s not covered by a warranty (see post #174 here).
Both of these, like any blind purchase from a major brand … would be very high risk purchase and I would avoid both of them. I would rather buy a 6" layer of low cost polyfoam or buy some other low cost alternative and sleep on it temporarily until I could buy a good quality/value mattress than buy either of these mattresses.
Just in case you haven’t read it yet … I would also read the tutorial post here which has all the basic information, steps, and guidelines you will need to make the best possible choice … and know how and why to avoid the worst ones.
