8 Best Memory Foam Mattress Toppers of 2026

ViscoSoft is unusually specific about its foam. The Restore HD Select uses what it calls DensityCore memory foam at 3.1 lb per cubic foot, and the company says most toppers use 2.0 to 2.5 lb foam that bottoms out sooner. The foam is gel-infused and cut with vertical airflow channels to move heat away. It comes in 2, 3 or 4 inches and in odd sizes such as Twin XL, Full XL, short queen and short king, which suits dorm beds and RVs. The cover zips off and goes in the washing machine, and it has a beaded non-slip mesh base and gel-lined straps to stop the topper sliding. Prices start at $129.95 for a 2-inch twin, and a 3-inch queen was $179.95 on sale when we checked. ViscoSoft offers a 90-day money back guarantee and a 5-year warranty. The trade-off is feel: ViscoSoft describes it as medium-firm, so sleepers who want to sink deeply may prefer a softer foam.

Subrtex sells a straightforward gel-infused memory foam topper with one big advantage: support after the sale. It comes with a 180-day guarantee and a 10-year warranty, the longest return window here and a warranty as long as Tempur-Pedic's. The foam is a slow-response memory foam that Subrtex says relieves pressure, and the company says it ran a 360,000-cycle fatigue test to check durability. All three thicknesses, 2, 3 and 4 inches, are sold in twin through California king, and the topper ships with a removable fitted cover. The foam is CertiPUR-US certified. A 2-inch twin was $99.99 when we checked, a 2-inch queen $159.99, a 3-inch king $209.99 and a 4-inch king $239.99. Subrtex does not publish a foam density, so it is harder to compare with ViscoSoft on how firm or lasting the foam is, and the thicker sizes cost close to the top pick.

The TEMPUR-Topper Supreme name is no longer on Tempur-Pedic's store; the TEMPUR-Adapt Topper is its current 3-inch model, alongside the 2-inch TEMPUR-Cloud. It uses TEMPUR-Material, the same foam as the company's mattresses, which Tempur-Pedic says is more durable than ordinary memory foam and responds to your weight, shape and temperature. The cover zips off, is machine washable and is dust mite and allergen resistant, and Staytight corner straps fit mattresses up to 13 inches deep. A queen was $359 when we checked, and the TEMPUR-Adapt + Cooling version, with a cool-to-the-touch fabric, adds $80. The topper ships free and carries a 10-year limited warranty. The catch is the return policy: Tempur-Pedic says that given the personal nature of the product, it cannot accept returns. That makes it a strong choice for people who already know they like Tempur-Pedic's feel, and a risky one for anyone trying memory foam for the first time.

Lucid sells the budget way into thick memory foam. Its Gel Memory Foam Topper comes in 2, 3 or 4 inch profiles, and buyers pick an infusion: cooling gel, bamboo charcoal or lavender. Lucid says the gel pulls heat away from the body and that a ventilated design keeps the foam breathable. Sizes run from twin to California king, and Lucid also lists split king, split queen and split California king halves for split and adjustable beds. A 2-inch twin was $49.99 when we checked, a 2-inch king $89.99 and a 4-inch queen with cooling gel $119.99. The foam is CertiPUR-US certified. The savings show in the extras. There is no cover, the foam is spot clean only, the sleep trial lasts 30 nights and the warranty runs 3 years. Put a mattress protector on top and Lucid is a cheap way to try a deep layer of memory foam, but returns need to happen within a month.

Sleep Innovations combines a thin layer of memory foam with an easy-care cover. The topper is 2 inches of memory foam infused with real green tea and cooling gel, and the company says its open-cell foam is designed to reduce heat while the green tea keeps the bed feeling fresh. Sleep Innovations rates the support as medium and says the foam suits any sleep position and resists sagging. A soft-knit cover lets air through and goes in the washing machine, which is unusual at this price. The topper is sold in three sizes, Twin XL, queen and king, priced from $119.99 to $169.99 when we checked, with the king at $169.99. Sleep Innovations backs its toppers with a 10-year warranty. The limits are range and depth: there is only one 2-inch thickness, no twin, full or California king size, and the product page does not state a sleep trial.

Bear's Pro Topper is the copper option among these memory foam picks. It adds 3 inches of copper-infused memory foam that Bear says contours to the body for pressure relief while drawing heat away. Bear pairs the foam with a circular knit cover that it says is breathable and cool on contact, and the cover unzips so it can be laundered. The foam is CertiPUR-US certified, sizes run from twin to California king, and the topper is HSA/FSA eligible. Shipping and returns are free within the contiguous US. When we checked, the topper was $224.25 with the code BF35, down from $345 for the default size shown. Bear notes that a topper will not fix a sagging mattress, which is a fair warning for anyone hoping foam will rescue a worn bed. The product page does not state a topper warranty or trial length, so check those before you rely on a return.

Linenspa is the cheapest way onto this list. Its Gel Memory Foam Mattress Topper is polyurethane memory foam with thousands of tiny gel beads that Linenspa says capture and spread heat, and a green tea version is also sold. It comes in 2, 3 and 4 inch profiles and in nine sizes, from a cot through Full XL and short queen to California king, which is the widest range here. The product page showed $44.99 for a 2-inch cot when we checked, and the variant list priced a 2-inch twin at $39.99 and a 2-inch king at $79.99. The foam is CertiPUR-US certified, ships free in 1 to 3 business days and arrives rolled, needing 24 to 72 hours to expand. The low price comes with limits: the foam is spot clean only, there is no cover, the warranty is 3 years and the page does not list a trial. Linenspa itself recommends putting a mattress protector over the topper.

Nectar's Softer Mattress Topper is a thin, soft layer aimed at side sleepers. It adds 2 inches of open-cell gel memory foam that Nectar says contours to ease pressure on shoulders, hips and back, and it sits under a cover with cooling yarns woven in. Nectar also sells a Firmer topper for people who need more support rather than more give. The foam is CertiPUR-US certified, and the toppers are light, from 10 pounds for a twin to 22 pounds for a king. The product page listed it at $199 when we checked, with free shipping and returns. Nectar offers a 100-night home trial, which gives time to judge the feel, but the warranty on the topper is only 1 year, the shortest stated on this list. At $199 for 2 inches, buyers who want deeper contour can get 3 or 4 inches from ViscoSoft or Subrtex for similar money.
