Memory foam has an 81% approval rating, which is higher than any other mattress material. Customers love memory foam for its low bounce, “hugging” feel, strong motion isolation, and body contouring. Once you’ve done the research and decided on memory foam, the only question is which brand to choose from.

Top Brands

Top-rated memory foam mattress companies include Casper, Novosbed, Tempur-Pedic, and Loom & Leaf. All four mattress brands are available for purchase online, but their products and policies vary.


Density is the greatest indicator of quality and durability in memory foam mattresses. Novosbed, Loom & Leaf, and Casper publish their memory foam densities online. Tempur-Pedic does not communicate foam densities to their customers.


An extensive mattress selection within a single brand makes shopping more complicated. Tempur-Pedic offers over 14 mattress models with perplexing names and features. In contrast, Casper sells one “universally comfortable” model, which may or may not actually suit individual comfort needs. Loom & Leaf offers slightly more selection with their “Relaxed Firm” or “Firm” options. Novosbed offers a single mattress model in Soft, Medium, or Firm to satisfy a full range of comfort needs.  

Sleep Trial and Firmness Guarantee

When it comes to sleep trials, longer is better. Of the four major memory foam retailers, Novosbed offers the longest sleep trial for their mattresses. Their Perfect Firmness Guarantee also offers customers a free Comfort+ adjustment kit to easily alter mattress firmness. Loom & Leaf’s sleep trial lasts only 75 nights, and Casper’s is slightly longer at 100 nights. Tempur-Pedic offers a 90-night sleep trial to online customers, but retail store purchases are subject to the retailer’s policies. Loom & Leaf, Casper, and Tempur-Pedic do not offer firmness guarantees with their mattresses.


Companies like Casper and Novosbed sell their mattresses exclusively online, which means their policies are consistent and reliable. Mattress companies that sell through third party retailers – like Tempur-Pedic – may be subject to different policies.
