About the Sleepy's Full Basic Foam Mattress 6

The Sleepy's Basic Foam Mattress 6 is a firm all-foam mattress in full size, 75 by 54 inches. It is a simple foam-core build that assembles in under 20 minutes and is pitched at pressure point relief. It suits budget shoppers and guest or kids' rooms that want a firm, basic foam bed. Against rival foam mattresses it lacks the cooling layers, edge support and motion isolation that pricier models add, and its 3-out-of-5 rating from 428 buyers points to uneven satisfaction.

Firmness is too hard for many side sleepers
  • Thin basic foam gives little edge support
  • Sleeps warm compared with foam beds that have cooling layers
  • Middling 3-out-of-5 rating across 428 reviews
  • No motion-isolating or hybrid layers at this tier
  • What reviewers say

    • 3 / 5428 ratings

    Buyers are split: some find the firm foam supportive and easy to set up, while many say it is too hard, breaks down quickly or sleeps hot. The 3-out-of-5 average across 428 ratings reflects that mixed reception.

    Questions and answers

    Is this mattress good for side sleepers?
    Mostly no. It is a firm foam bed, and side sleepers often need a softer surface to cushion shoulders and hips. Back and stomach sleepers tend to be happier with it.
    Does it need a box spring?
    No. It is an all-foam mattress and can sit on a flat foundation, platform bed or slatted frame. A solid, supportive base helps it last.
    How long does setup take?
    Sleepy's says it assembles in under 20 minutes. Expect to unroll or unpack the foam and give it time to expand to its full 6-inch height.
    Will it sleep hot?
    Basic foam without cooling layers tends to retain heat. If you sleep warm, a mattress with gel or breathable foam is a better fit.
    What size is the full?
    The full measures 75 inches long by 54 inches wide, the standard full size. Check your frame fits before buying.
