Variants In Thickness

Each variant offered by Signature Sleep varies in the thickness of the memory foam and the high-density foam layers. The thicker the layers, the higher the cost and the more expensive the mattress becomes. Strike a fair balance based on the level of comfort you desire and the size of your wallet.

6 inch – This variant consists of a 1.5-inch layer of Memory Form in addition to 4.5 inches of high-density foam. The most affordable of the lot, this is the right choice for those on a tight budget.

8 inch – This variant offers 2 inches of premium Memory Foam over 6 inches of high-density foam and offers markedly improved comfort and durability over its cheaper alternative. While it does come with a price premium, it will certainly pay off in the long run.

10 inch – With a 2-inch layer of Memory Foam atop an 8-inch layer of high-density foam, the 10-inch variant enters the exquisite territory, well outside that of some buyers. Opt for it if the added luxury and ruggedness appeal to you.

12 inch – The 12-inch variant offers an incredible 4 inches of Memory Foam over 8 inches of high-density foam. The most expensive of the lot, it comes with a significant premium. It offers incredible durability and reliability. At a higher cost than the 10-inch variant, we recommend that you perform due diligence before splurging for this one.

Available Sizes

These mattresses come in a variety of sizes that caters to most households. They come in Twin, Twin XL, Full, Queen, and King variants that offer flexibility based on the size of your beds and bed frames.

Signature Sleep Memoir memory foam mattress available thickness and sizes

Twin – This variant of Signature Sleep’s premium mattresses measures 75 inches by 39 inches. Their smallest variant on offer, it is perfect for those who have small rooms. 39 inches is the minimum space one would require for a comfortable snooze.

Twin XL – This variant is longer than the regular Twin variant. It measures 80 inches by 39 inches. This one is for those who stoop to enter rooms, the taller ones among us. This bed can only fit a single individual.

Full Size – A Full mattress is significantly wider than Twin ones, measuring 75 inches by 54 inches. Indulge in a bit of luxury as you gain more space to wiggle in. But be prepared for a trade-off; a compromise in living space.

Queen – The most popular mattress size today, Signature Sleep’s Queen mattresses measure 80 inches by 60 inches. They expand both in length and width from the Full variant. Opt for these if you wish to share your bed with a partner or a pet.

King – Offering the most amount of sleeping space, the King variant is larger than all the other mattresses, at 80 inches in length and 76 inches in width. It’s perfect for those with a partner, be it a person or a pet.

When picking the size of your mattress, there are several factors one must take into account. If living space ranks higher up on your priorities, a smaller mattress may be more suited to your needs. If you wish to share your bed, a bigger one will certainly be necessary. Your sleeping posture also plays a role. If the sleeper is tall, a Twin bed will not be up for the occasion. And you do not have to worry about sizing when it comes to bed frames, these mattresses are compatible with any of the standard-sized bed frames on the market today. Signature Sleep’s Memoir range of Memory Foam Mattresses does not currently provide Narrow Twin and California King variants to customers.


One can consider Signature Sleep’s Memoir range to be moderately priced. At its price, it offers several features that make it a worthy proposition. The cost varies based on two factors, the size of the mattress and its thickness. The thicker or larger the bed, the higher the cost. But sometimes a larger mattress is an absolute necessity, especially when you need to share it with a partner. Thicker mattresses offer more comfort and will last longer, so do keep that in mind as well. Spending more now might make a significant impact on how long the mattress will last. From under a hundred dollars to over four hundred dollars, the range offers something for everyone.

Its rock-solid durability ensures that it will be an investment that will pay off in the years to come. You won’t have to think of replacing your mattress for a while. A 15-year limited warranty also provides peace of mind while ensuring that you can always do something if something goes wrong.

Warranty Offered

Signature Sleep has 50+ years of industry experience and offer up to 15 Year warranty of all the mattress

Signature Sleep offers its customers a 15-year limited warranty on its Memoir range of mattresses. One can claim their replacement if the product they received is either of defective material or inferior workmanship. Keep your original bill of purchase ready in case something of the sort occurs. Additional charges in the form of replacement fees, shipping, and handling fees may apply. Claims may be rejected if they are due to accidental spills or other forms of damage.


Once you’ve got yourself a solid mattress from Signature Sleep’s range, assembling it is no trifle. It ships in a box that is very easy to transport. And at less than 40 pounds, one can easily lift it and take it to their bedroom without much of a hassle. One can bid farewell to those days of perfectly lining up their mattresses to get them through their bedroom doors. Now that you’ve got the box in place, pull the mattress out, cut the outer bag, and roll out the compressed mattress on a flat surface. Once the mattress is in position, cut the outer layer of plastic with a pair of scissors. Give it 72 hours to expand to its full size, you can start using it before that as well. And there you have it, your very own memory foam mattress!


Now that you have your brand-new memory foam mattress, here are some things you need to keep in mind to ensure that it is in its peak form for longer and lasts in your household for years to come. Follow these steps and your mattress will serve you for a long time.

  • Give your mattress sufficient time to air out and expand completely. Don’t assume that your mattress is defective until you wait for the stipulated amount of time for the expansion to occur.
  • Clean your mattress often to ensure that foreign elements don’t cause allergic reactions. Use a slip-on cover to protect your mattress from dust, spills and other mishaps. Don’t be tricked by the fabric cover that the mattress comes with by default, because it can neither be washed nor removed. Buy a new one to customize the visual appearance of your bedroom while ensuring that your mattress is protected as well.
  • Rotate your mattress periodically. This will ensure that all sides of the mattress wear out evenly.
  • Refrain from spilling fluids onto your mattress. They may damage the foam, causing materials to compress which may result in the mattress beginning to sag or break down.
  • On that note, do not attempt to use cleaning fluids on your mattress, for they may have the same consequences as spilling liquids onto it.
  • If you have children in your home, do not let them jump or bend your mattress. Damage caused in such a manner will void your warranty.


With impressive reviews across the board, with customers praising it for the features it offers to provide a delicate and dreamy experience, Signature Sleep’s Memoir range of Memory Foam mattresses is one that we highly recommend. From adapting and offering customized solutions to a variety of ailments to lasting through the rigorous routines that life may throw at it, it has earned its solid reputation among households. This mattress is certainly a welcome addition to your home, with features that will make every night feel like the first one.

The firm high-density foam ensures that the bed provides you with a solid feel, every single time. And with a 15-year limited warranty, you can be sure of keeping it around for a while.
