Purple Mattress deals and sales for May 2025: Up to $400 off Purple's cheapest bed

After a mega Purple mattress sale in May this month's deals aren't quite as all-encompassing — although $400 off the budget-friendly Flex mattress at Purple is possibly the best price drop we've seen in weeks.

The Purple Flex might be the cheapest mattress in the Purple line-up but it still features the unique GelFlex Grid technology that has earned Purple a place among our top-rated mattresses you can buy online.

This GelFlex Grid delivers a mix of cushioning and support our testers have described as "weightless" and it's used in all Purple mattresses. But if you want anything other than the PurpleFlex, you'll have to wait for the next mattress sale, as this is the only bed currently discounted at Purple.

Purple Flex Mattress: twin was $699 now $499 at Purple
The Purple Flex Mattress is the company's most affordable model, although don't worry, you'll still find a layer of GelFlex technology. This unusual hyper-elastic polymer grid conforms to joints to relieve pressure, while the responsive feel is both soft and firm, depending on your needs. But it can take a while to get used to the Grid, which is particularly noticeable in the thinner build of the PurpleFlex. The best deal right now is on the full size, which is $400 off in the sale and is reduced to $799 (was $1,199.) But $300 off a queen is still a good saving, bringing it down to $999 (was $1,299.) You'll also get a 100-night trial and 10-year warranty.

Which Purple mattress should you buy?

Purple has three mattress line-ups: the Essential collection (starting from $699), the Restore collection (starting from $1,999) and the Rejuvenate collection (starting from $4,499). The Essentials collection consists of memory foam mattresses, while the Restore and Rejuvenate collection are both hybrid mattresses.

The Essentials and Restore collection rate among the best mattresses in a box. The thicker, plusher Rejuvenate models are delivered flat and come with bonus free white glove delivery. All three collections feature Purple's patented Purple Grid mattress tech - an innovative hyper-elastic polymer that behaves more like a gel.

The Purple grid is designed to flex under your pressure points and adapt to support your body where it needs it the most. This grid layer is comprised of more than 2,800 open-air channels, so body heat dissipates and you don't feel too hot or too cold while you sleep.

The PurpleFlex Mattress is the cheapest mattress by Purple, yet it still comes with Purple's patented Purple Grid mattress tech. Under this grid sits a base support foam. The Purple Original and Purple Plus mattress have a similar build, but each design increases the level of support and comfort (and foam).

The Purple Restore Mattress is a hybrid collection featuring foams, coils, and the GelFlex Grid. The coils add even more support and response to these mattresses, making it easy for sleepers to change position and adjust.

The Purple Rejuvenate is the company's premier mattress line with a quilted Euro top and enhanced comfort layers. They also contain the upgraded GelFlex Grid Plus (and the luxurious Purple RejuvenatePremier Mattress contains two layers of grid technology).

As a side note, Purple also holds a spot on our best dog bed guide. The Purple Pet Bed is a high-tech mattress for your furry friends. It's hypoallergenic, non-toxic, and vegan. It's backed by a 100-day free trial.

The Purple Mattress uses the Purple Grid to eliminate pressure points and allow airflow so you can sleep cool and comfortable. The Purple Grid is engineered to flex directly under your pressure points while supporting the rest of your body. In other words, it'll cradle your shoulders and hips while fully supporting your back. This means your back will be naturally aligned while you sleep.

Beneath the two-inch Purple Grid, you'll find Purple's dual layered comfort foam. The bottom layer is firm and offers excellent support, whereas the upper layer is soft and responsive. At the very top of the mattress is Purple's SoftFlex cover. The breathable design promotes airflow so you can sleep cool and comfortable.

The Purple Plus is a luxurious mattress and a step up from the Purple Original. It features two extra inches of foam than its predecessor. Overall, it's rated a medium firmness, but Purple also promises an 'adaptive' feel — soft where you want a mattress to feel soft, and firmer where you need extra support.

The Purple Plus is also great at relieving pressure points, and all sleep positions were well-suited on this mattress. It feels soft and cradled under your head, neck, arms, and legs, but is firmer under the shoulders, hips and lumbar spine. In our testing, we rated it one of the best mattresses for back pain.
