Tom's Guide's best cheap topper: a ventilated gel-foam slab that adds plush, side-sleeper-friendly cushioning and regulated temperature better than expected for the price. But there's no cover or straps, the 4-inch version is very squishy, and Tom's Guide questions its durability, citing owners who report tears and dents.

Top complaints

  • Too soft and hard to move on

    Tom's Guide found the 4-inch version very squishy, with the pelvis sinking for back and stomach sleeping and shifting positions an arduous task; a guest tester who likes firmer beds did not get on with it. Amazon owners disagree on softness, with some finding it too squishy or sinking too much.

  • Durability doubts

    Tom's Guide lists 'not as durable' as a con and says a number of owner complaints claim it tears easily and leaves dents after a while.

  • No cover or straps

    It's a bare slab of foam: no cover (so not washable) and no anchor straps unless you buy the separate cover, which has non-slip dots (Tom's Guide).

What owners love

  • Plush pressure relief for side sleepers

    Tom's Guide found it cushioned the shoulders and knees in side sleeping without the hips dipping too far.

  • Better cooling than expected for the price

    Ventilated, gel-infused foam earned 4/5 for temperature from Tom's Guide, with only minimal trapped heat on warmer nights.

  • Cheap, popular and widely sold

    A queen runs $69.99 to $119.99 at list depending on thickness, with a 30-night trial and three-year warranty direct from Lucid; Amazon's summary says owners call it comfortable and say it changed their sleep.

If that catch is a deal-breaker

Highly ranked mattress toppers whose biggest complaint is something else.

#1 in mattress toppersViscoSoft 3 Inch Memory Foam Mattress Topper (Select High Density)

Wirecutter's memory-foam pick and Sleep Foundation's pick for spinal alignment: dense, supportive pressure relief that doesn't feel like quicksand, with corner straps and a washable cover. But about half of Wirecutter's testers found it too firm, memory foam can still hold heat, and Sleep Foundation noted an initial off-gassing smell and only average durability.

Its catch: too firm for some, too sinky for others#2 in mattress toppersBirch Plush Organic Mattress Topper

An organic latex topper that Tom's Guide, Sleep Foundation and AARP all recommend for responsive support, no chemical off-gassing, and a 10-year warranty with a 100-night trial. But it's pricey and firmer than the 'Plush' name suggests, though AARP found it too soft for heavier sleepers. It has no straps or removable cover, and it didn't cool Tom's Guide's tester in a heatwave.

Its catch: firmness doesn't match expectations#3 in mattress toppersTempur-Pedic TEMPUR-Adapt 3-Inch Mattress Topper

Tom's Guide's best overall and Sleep Foundation's best cooling pick: plush, hugging Tempur foam with a 10-year warranty that side sleepers love. But it can't be returned, testers split sharply on its deep sink (Wirecutter dropped it, and CNN's co-tester compared it to sleeping in a ditch), the standard cover can sleep warm, and 16% of Amazon ratings are 1-2 stars.

Its catch: no trial and no returns
