Temperpedic Grand Bed

Hi zman1,

The Select Foam is more of a “match” based on design, foam density, and feel while the Restava would be more of an “equivalent” in terms of softness / firmness and feel but not a match in design or foam density (see post #9 here about matching one mattress to another).

The Rize is made by Mantua Manufacturing (who also makes bedframes) and is interesting and somewhat unique because the top 2 models in the lineup have the ability to lower the foot of the adjustable to a lounging position and the top model also has 5 adjustable sections instead of just 4. You can see a video of the Rize Relaxer and the Rize Contemporary here. Other than that they have features that are similar to other adjustable bed brands and models and I would compare them feature by feature based on which features vs price are most important to you. The remote on the Relaxer looks exactly like the remote on the Reverie Deluxe so I don’t know if Reverie is involved in its manufacturing.

The single biggest factor in the durability or memory foam and polyfoam is foam density but there are also other variables involved in durability and the useful life of a mattress which you can read in post #4 here. All other factors being equal … higher foam densities trandlate into greater durability and longevity.

Foam quality, durability and PPP are not connected at all however. A mattress is only as good as its construction and the quality of the materials inside it and any quality or density of foam can be made in soft or firm versions. You can’t “feel” the quality or durability of a foam. Even the cheapest foams and components can feel the same as higher quality materials in a showroom … and for a while after that … they just don’t maintain their “feel” and performance for as long. Foam softening that is common with low quality/density materials and the loss of comfort and/or support that goes with it is the reason most mattresses need to be replaced and this isn’t covered by a warranty.

If you are dealing with the same mattress manufacturer and seller the “value” of their mattresses will generally be fairly consistent across their entire lineup and budget range (higher priced mattresses will contain more costly materials) but when you are comparing different manufacturers or retailers then “value” can vary widely and it’s often the case that you can get much less than you pay for … particularly if they are major brands such as Tempurpedic.
