    What reviewers say

    Saatva Classic

    With 4.8 out of 5 from 6,625 ratings and a 96% satisfaction figure cited by Saatva, the Classic is one of the most-reviewed online mattresses. Owner surveys report better sleep and less back and neck pain than on previous mattresses.

    Pros
    • 93.9% of surveyed owners said it helped alleviate back pain
    • 91% said they wake up more refreshed than on their old mattress
    • 97.5% would recommend Saatva to friends and family
    • Hotel-like pillow-top comfort at a lower price than luxury store brands
    Cons
    • Some sleepers find the Luxury Firm firmer than expected
    • Edge support and motion isolation trail foam rivals
    • Heavy mattress is hard to move or rotate alone

    Sealy Posturepedic Seafield 13" Tight Top Mattress Set

    The 4.2-out-of-5 rating from 35 ratings is decent but mixed. The most detailed complaints center on delivery and product mix-ups rather than the mattress design itself, including wrong mattresses delivered twice and a unit that arrived about 11 inches thick instead of 13.

    Pros
    • Supportive medium feel for side and back sleepers
    • Sturdy edge support from the Coil Edge
    • Box spring included in the set option
    Cons
    • Wrong mattress delivered more than once
    • Delivered unit measured about 11 inches, not 13
    • Some buyers found it extremely painful to sleep on
    • Returns described as a headache

    Questions and answers

    Which is better for back pain?
    The Saatva Classic is the stronger pick. It has Lumbar Zone technology, three firmness levels and buyer survey claims of back pain relief. The Sealy Seafield is a medium tight top with no firmness choice.
    Is the Saatva Classic worth the extra money?
    If you keep a mattress 8 to 10 years, the $1,061.70 gap works out to about $11 a month. You get a 365-night trial, three firmness options and GREENGUARD Gold certification. On a tight budget, the Sealy set is the practical choice.
    Which lasts longer?
    The Saatva Classic has the edge on paper: over 1,000 triple-tempered recycled steel coils in a dual-coil design built to resist sagging. The Sealy uses 726 coils and does not publish a durability claim.
    Which is better for side sleepers?
    The Sealy Seafield is listed for side sleepers and its medium gel foam cushions shoulders and hips. The Saatva Classic also works for any sleep position if you pick Plush Soft or Luxury Firm.
    Does either come with a box spring?
    The Sealy Seafield does when you choose the set option, in 9-inch standard or 5-inch low-profile height. The Saatva Classic is mattress only; a foundation costs extra.
    Can I use either on an adjustable base?
    Yes. Both are adjustable-base compatible. Saatva notes its Classic fits an 11.5-inch base height.
