Our verdict on each

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

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.

The Little Green Sheep

Pros

  • A long trial of 100 days nights at home, well above the 100 typical of the mattress ranking.
  • Return postage is free at £0, so a trial costs nothing extra if the fit is wrong.
  • Support runs on email, phone and chat, giving more ways to reach a person than most brands in the ranking.

Cons

  • The 5 years warranty is below the 10 across the mattress ranking, and well short of lifetime cover.
  • Delivery reaches GB only, so buyers outside the UK are not covered.
  • Firmness covers medium and firm, so there is no soft or medium-firm option.

Who each suits

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.

The Little Green Sheep

Who it suits

  • UK households shopping a natural-material mattress with a long home trial
  • Parents furnishing a cot bed who want cotton and wool bedding in the same order

Who should look elsewhere

  • Anyone outside GB, who will not find delivery
  • Buyers who want a soft or medium-firm feel, since firmness covers medium and firm
  • Anyone after a very long warranty, given 5 years against lifetime cover

Questions about each

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.

The Little Green Sheep

How long is the trial period on the mattress?+

The Little Green Sheep offers a trial of 100 days nights at home, which is longer than the 100 across the mattress ranking. The return window is the same length at 100 days, so the two limits do not clash. Sleeping on it for months is a realistic option here.

What does returning a mattress cost?+

Return postage is free, listed at £0. That matters more for a mattress than for smaller bedding, because the cost of sending one back would usually fall on the buyer. Alongside a trial of 100 days nights, the free return removes most of the risk from trying it.
