Our verdict on each
Amerisleep
Amerisleep sells memory foam and hybrid mattresses with different firmness and construction choices. Its AS3 is described as a medium-feel all-foam mattress combining Bio-Pur foam with HIVE zoned support; the AS3h uses foam and coils. The company says its mattresses use a cotton-rayon fire barrier instead of fiberglass and advertises a 100-night trial and 20-year...
Casper
Casper suits buyers in the US and Canada who want a long home trial without a return charge, and it prices a queen mid pack rather than at the bottom. The trial of 100 days nights, backed by a 10 year warranty, is the reason to look here before cheaper foam options.

Pros and cons
Amerisleep
Pros
- AS3 combines Bio-Pur foam with HIVE zoned support and a medium feel.
- The lineup includes all-foam and hybrid models.
- The brand advertises a 100-night trial and 20-year warranty.
Cons
- Several models differ mainly in feel, so the right choice depends on personal comfort
- The lineup centers on foam and hybrid designs rather than other mattress types
Casper
Pros
- A trial of 100 days nights runs well past the site median of 60 nights.
- Free delivery is included at a minimum order of $0, and old mattress removal is offered with it.
- A warranty of 10 years sits above the site median of 5 years.
Cons
- Assembly included: no, and the return fee is $0, so nothing in the delivery covers a frame build.
- Casper sells into US and CA only, so buyers elsewhere sit outside its delivery and cover terms.
- A rank of 17 out of 50 brands on queen price means the headline number is not the cheapest on the list.
Who each suits
Amerisleep
Who it suits
- Shoppers comparing foam or hybrid mattresses and interested in the AS3 medium feel.
Who should look elsewhere
- Buyers looking for one feel or construction to suit every sleeper.
Casper
Who it suits
- Buyers in US and CA who want to sleep on a mattress for 100 nights before deciding.
- Shoppers who want free delivery and old mattress removal handled on the same visit.
- Anyone building out a full bed, since bedding covers sheets, duvets and duvet covers alongside the mattresses.
Who should look elsewhere
- Buyers chasing the longest warranty, since Newton Baby lists lifetime cover against 10 years here.
- Buyers who need the bed built for them, since assembly is not included at delivery; Coop Sleep Goods is the other brand in this group to compare that point against.
- Sleepers who want a firm setting, since firmness stops at soft, medium and medium firm; Eve Sleep lists the same hybrid and memory foam builds, so feel is worth comparing there.

Questions about each
Amerisleep
How does AS3 differ from AS3h?+
Amerisleep describes AS3 as all foam and AS3h as a hybrid combining foam and coils.
What is Bio-Pur foam made from?+
Bio-Pur foam is made with castor bean oil instead of petroleum. This plant based base is designed to feel breathable, a quality many memory foams lack. It appears in several mattress models in the range, giving sleepers a foam option that differs from traditional petroleum based memory foam.
Casper
What does a Casper queen mattress cost?+
The Casper One foam mattress is listed at $899 for a queen, and that is the figure most comparison tables use. It sits in the middle of this group rather than at either end, so anyone who has found a lower number should weigh what the trial and warranty come with before moving across.
How long is the Casper home trial?+
The trial runs 100 nights, longer than the site median of 60 nights. Sleeping on a mattress for that stretch in your own room is the whole point of the arrangement, and the return fee is $0, so changing your mind later adds nothing to the outlay.
