Shopping for a mattress this Presidents' Day? Why I recommend checking Amazon's deals first

1. Siena Essential Memory Foam mattress: Twin $149 now from $127.13 at Amazon
Siena is a very reputable budget mattress maker, even taking the top spot in our best cheap mattress guide. The Essential is Siena's most affordable model, with a queen going for just $239 (was $279) at Amazon. If you buy directly from Siena you'll pay full price, so this Amazon deal is the strongest discount we're seeing on this mattress. The medium firm feeling of this mattress will suit most sleep positions but, at 8" tall, heavier bodies will require something with more support, like the Nectar Classic. Your purchase is covered by a 180-night trial and 10-year warranty.

2. FDW 8" Gel Memory Foam mattress: $159.99 now from $98.98 at Amazon
Like the Siena, this budget mattress stands at 8" tall. It features two inches of gel memory foam over six inches of high-density base support foam. While we haven't tested this model, we reckon the high-density foam will create a medium-firm feel, making it a good all-rounder for growing kids or occasional guest beds. Be warned, though, Amazon doesn't offer sleep trials with this mattress so buy at your own risk. But if you're looking for a quick cheap solution, this could be the one for you. A twin size is now 38% off, taking it under the $100 mark.

3. Litespace Hybrid mattress: $289 now from $199.99 at Amazon
This queen size mattress has a huge $90 reduction, offering a hybrid sleep experience for under $200. It stands at 12" tall and has six layers of supportive materials including a breathable cooling surface, comfort memory foam and supportive pocket springs. Unfortunately, it doesn't come with a sleep trial, so buy at your own risk.

1. Tempur-Pedic TEMPUR-Adapt memory foam mattress topper: $299 now from $171 at Amazon
The Tempur-Adapt is our best mattress topper right now, offering superior comfort and support. It can extend the life of your mattress and add a premium feel to any bed. The signature Tempur-material is renowned the world over for its pressure-relieving properties and also reduced motion transfer so its perfect for couples. Right now, you can find this item's cheapest price at Amazon which is more than $40 cheaper than buying directly from Tempur-Pedic in the Tempur-Pedic mattress sale. A queen size costs $198.49 (was $419), which is better than half price.

2. Iululu 3" memory foam mattress topper: $49.59 now from $42.16 at Amazon
At the opposite end of the price spectrum, this best-selling mattress topper is up to 20% off at Amazon right now, with a queen going for $59.67 (was $74.59). Despite its low price point, this comfy topper is crafted with gel-infused memory foam, offering pressure relief and body-contouring comfort. You can also upgrade to a 4" version, which has an even bigger reduction - $94.99 for a queen (was $133.33), which is 29% off.
