While not a mattress manufacturer, Costco, a major chain of warehouse stores, is constantly featuring memory foam mattress and toppers that are made exclusively for them. If you are in the market to buy something with memory foam in it and don’t want to spend much, Costco has just that.
Brands of memory foam mattresses that Costco sells are Blackstone, Brentwood Home, Novaform, Simmons Beautyrest, Sleep Science, Thomasville, Tempur-Pedic, Comfort Tech, and Eight Sleep Jupiter.*
The memory foam layers in the Novaform™ and Sleep Science™ mattresses are lower in density, and the feel is more spongy. Overall, don’t expect a high quality, but at least they are priced accordingly.
Simmons and Tempur-Pedic are among the mattress establishment, adapting to keep up with the newcomers in the boxed-bed movement.
