After doublechecking, I find the Novaform and the Sleep Innovations mattress I mentioned earlier are indeed made by the same company. IIRC correctly, there is no difference between the two lines. One caution, We ordered the 14" for our home and while it is fantastic, it is a bit "high," which makes it a pain to deal with -- at least for my wife -- when putting on sheets, etc., plus the sheets are more $$.
Our son ordered the 8" and loves it. Our daugther has the 10" and loves it. My wife's two friends both ordered the 14" and as far as I know, they love them. I think there is also a 12" and maybe even a six-inch????
You have to poke around for them, the different thicknesses all seem to be on separate pages.
The plus on the bed for my daughter is she is away at college and had no way to cart a mattress back to her apartment, ordering through
Amazon meant free shipping to her door. I will say that the price has gone up, she (well, me) paid $240 -- and this was only a year or so ago. Maybe you can find it at
Walmart or Costco cheaper.
I have also "heard" Casper is great, but the price seems way above the Sleep Innovations/Novaform prices. I have heard various ads on the radio lately offering $50 off on Casper, so if you google for Casper coupons or promo codes, you will probably find one.
