Do not choose a thickness solely on the assumption that thicker is automatically better. Thickness affects mattress depth and price, but it is not the same as firmness and does not by itself determine comfort — see our Mattress Thickness Guide for a fuller explanation.
Sizes and Available Thicknesses
Semi-Orthopaedic is listed across 8 standard Nigerian sizes, from Single (3×6ft) to Extra Large (7×7ft). Thickness availability varies by size: smaller sizes such as 3×6ft and 4×6ft are currently listed only at 6″–12″, while 4.5×6ft, 6×6ft and 7×6ft extend up to 24″. Always check the price table above for the exact combinations currently listed, and measure your bed frame's internal dimensions before ordering — our Mattress Size Guide explains how.
How to Choose Size and Thickness
Start with your bed frame, not the mattress name. Measure the inside sleeping area to confirm width and length, then decide on thickness. Mattress thickness can affect depth and how the mattress performs under load, but the appropriate choice also depends on mattress construction, number of sleepers, comfort preference, bed-frame height and budget — not body weight alone. For a full explanation of how thickness works and how to choose it, see our Mattress Thickness Guide in Nigeria.
What Is a Semi-Orthopaedic Foam Mattress?
Semi-Orthopaedic is positioned as a firmer option than Olive Foam's regular comfort ranges (Olive Foam and Olive Damask), with more cushioning than Full Orthopaedic. It carries a 5 Years Factory Warranty and sits in the middle of Olive Foam's warranty tiers, between the 4-year warranty on Olive Foam/Olive Damask and the 10-year warranty on Full Orthopaedic.
“Semi-orthopaedic” is a widely used commercial term in the Nigerian mattress market rather than a regulated medical classification, and it should not be interpreted as a guarantee that a mattress will treat or cure a medical condition.
Semi-Orthopaedic vs Full Orthopaedic
The main difference between the two ranges is firmness, warranty and price rather than one being universally better. Full Orthopaedic is the firmer option, with a 10-year factory warranty and a higher starting price of ₦145,992. Semi-Orthopaedic offers supportive cushioning with more give, a 5-year factory warranty, and starts from ₦85,998. For a full side-by-side comparison, see our Full Orthopaedic vs Semi-Orthopaedic comparison, or compare both ranges directly in our orthopaedic foam mattress buying guide.
Who This Range May Suit
Semi-Orthopaedic tends to suit buyers who want firmer, more durable support than Olive Foam's everyday comfort ranges, but do not want the full rigidity of Full Orthopaedic. In practice this covers many families furnishing a master bedroom, guest rooms that see varied occasional use, and hotels or guesthouses wanting a consistent, durable option across multiple rooms. For a broader look at how it compares against Olive Foam's full range, see our best orthopaedic mattress in Nigeria guide. Mattress firmness alone does not determine whether a mattress is suitable for someone with back pain — see our Best Mattress for Back Pain in Nigeria guide, which explains the evidence behind mattress firmness and back discomfort in more depth.
Warranty
Semi-Orthopaedic carries a 5 Years Factory Warranty, covering verified manufacturing defects in the foam core. If a defect is confirmed, Olive Foam Awka Depot arranges a replacement or repair at no extra cost, according to the applicable warranty terms.
To make a warranty claim, contact Olive Foam Awka Depot on WhatsApp at 08108310088 with clear photos of the defect. Per our published policy, claims are assessed within 3 working days, and approved claims are processed within 7 working days. This is separate from our standard exchange policy, which accepts exchanges for a different size, thickness or collection of equal or greater value within 48 hours of delivery. Full terms are on our refund and exchange policy page.
Mattress lifespan depends on construction, frequency of use, care, bed-base support and other factors. The 5-year factory warranty covers specified manufacturing defects according to its terms and should not be treated as a guaranteed comfort lifespan.
